[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 160,322, filed on March 12, 2021, which is incorporated herein by reference in its entirety. Background Art
[0003] Incontinence, or lack of control over urination or bowel movements, has a variety of causes but often involves damage to or weakness of the pelvic floor muscles and the nerves that innervate these muscles and associated organs. Electrical stimulation has been used to treat incontinence by directly stimulating the muscles or sacral nerves to improve control over urination and bowel movements. Summary of the invention
[0004] Lack of voluntary control over urination, defecation, incontinence, or any combination thereof, is a problem that can affect quality of life and lead to social embarrassment. Urinary incontinence, or loss of bladder control, fecal incontinence, loss of bowel control, or any combination thereof, is often associated with neurological problems.
[0005] Electrical stimulation has been used to treat incontinence by directly stimulating muscles, sacral nerves, or other pelvic nerves to improve control over urination and defecation. However, electrical nerve stimulation methods typically only provide one set of stimulation protocols and cannot be adapted to the subject's condition. This can result in over-stimulation or under-stimulation of the target area, leading to inadequate control over urination or defecation. Therefore, it would be beneficial to provide electrical stimulation that takes into account the subject's condition and adjusts the stimulation level accordingly.
[0006] In addition, traditional methods of treating incontinence ignore that the original human response (i.e., reflex) to prevent incontinence events may be insufficient, rather than non-existent. For some individuals who exhibit incontinence events, the innate mechanisms to prevent incontinence may not be completely absent, but insufficient. For example, some individuals with incontinence may experience insufficient preventive responses (e.g., muscle contraction of at least one pelvic floor muscle) to prevent leakage events in response to increased intra-abdominal pressure. In some cases, the leakage event may be urine, or gas or stool. In addition, some individuals with stress incontinence may show delayed responses to preventing incontinence events in response to stress events. Alternatively, some individuals may suffer from stress incontinence associated with urethral hypermobility (i.e., insufficient support), which may result in increased pressure transmitted to the bladder, followed by incontinence events.
[0007] Aspects of the present disclosure provide a method for preventing the onset of incontinence in an individual in need thereof, the method comprising: (a) implanting a sensor electrode and a stimulator electrode in the individual; (b) sensing a parameter associated with a response of the individual intended to prevent the onset of incontinence with the sensor electrode; and (c) providing electrical stimulation with the stimulator electrode, the electrical stimulation and the response preventing the onset of incontinence together.

[0027] Lack of voluntary control over urination or defecation, known as urinary incontinence and fecal incontinence, respectively, is a problem that can affect quality of life and lead to social embarrassment. Urinary and fecal incontinence can affect individuals of all ages. In some cases, older individuals may present with a greater prevalence of incontinence, with different pathophysiologies. Both urinary and fecal incontinence may involve damage, weakness, or overactivity of the pelvic floor muscles, which include but are not limited to the urethral sphincter and anal sphincter, and the nerves that innervate these muscles and associated organs such as the bladder, rectum, or anus.
[0028] Urinary incontinence can be classified into one of four main types: urge incontinence, stress incontinence, overflow incontinence, and mixed incontinence. Urge incontinence is often due to an overactive bladder. Individuals with urge incontinence have a strong and sudden need to urinate immediately, which often does not allow them enough time to go to the bathroom. Stress incontinence is often due to poor urethral sphincter function or excessive urethral movement or bladder neck movement. Individuals may experience stress incontinence during activities such as coughing, sneezing, laughing, or exercising. Overflow incontinence may often be due to poor bladder contraction or urethral obstruction. Mixed incontinence may include features of stress and urge incontinence. Incontinence often involves neurological problems, including but not limited to impaired nerve conduction between the brain and / or affected muscles, as well as neurological conditions or injuries (such as multiple sclerosis or stroke) or mental confusion. Other causes of incontinence include but are not limited to weakness of the pelvic or urethral muscles and pelvic prolapse.
[0029] Fecal incontinence, also known as bowel incontinence, is a loss of bowel control that causes an individual to accidentally pass stool from the rectum. Fecal incontinence can be divided into two main types: urge incontinence, passive incontinence, or a combination. Urge incontinence is caused by an overactive bowel. Individuals with urge incontinence have a strong and sudden need to pass a bowel movement immediately, which often does not allow them enough time to go to the bathroom. Passive incontinence is when an individual feels no urge to open their bowels despite the rectum being full and ready to pass stool. Individuals with passive incontinence are unable to consciously control their bowel movements, and stool can pass without them knowing it. Incontinence often involves neurological problems, including but not limited to impaired nerve conduction between the brain and / or affected muscles, as well as neurological conditions or injuries (such as multiple sclerosis or stroke) or mental confusion. Causes of fecal incontinence include but are not limited to nerve damage, anal sphincter damage, constipation, diarrhea, hemorrhoids, surgery, loss of rectal storage capacity, rectal prolapse, and rectocele.
[0030] Electro galvanic stimulation has been used to treat incontinence by training the pelvic floor muscles to improve strength and function and / or by stimulating the sacral nerves to improve urinary and fecal control. However, these electro-nerve stimulation methods cannot adapt to the subject's condition and environment and can only provide predefined stimulation protocols. This can result in over-stimulation or under-stimulation of the target area, resulting in insufficient control of the muscles involved in urination or defecation. Therefore, it would be beneficial to be able to provide electro-stimulation that takes into account the subject's condition and adjusts the stimulation level accordingly.
[0031] Provided herein is a device, system and method for preventing and / or reducing the severity of an episode of incontinence in an individual in need thereof. In some cases, an episode of incontinence may include urinary incontinence, fecal incontinence, or any combination thereof. The devices, systems and methods disclosed herein may treat subtypes of incontinence. In some cases, subtypes of incontinence may include urge incontinence, stress incontinence, overflow incontinence, or mixed incontinence.
[0032] In some cases, the devices, systems and methods described herein can increase bladder capacity. Bladder capacity can be measured as the maximum volume of liquid that the bladder can hold without causing pain or urination. In some cases, the bladder capacity of a healthy individual as a baseline value can include a liquid volume of about 400 milliliters (mL) to about 600 milliliters. In some cases, bladder capacity can be measured by ultrasound calculation of a static ultrasound image of the subject's bladder. The volume of the bladder can be measured by multiplying the length, width and height of the bladder measured on the static ultrasound image. Alternatively, or in addition to this, bladder capacity can be measured by cytometry, in which a catheter is inserted into the subject's urethra to fill, and urine volume can be measured. In some cases, the subject's bladder capacity may be reduced due to disease. In some cases, the devices and systems described herein can increase bladder capacity by one percentage point from baseline bladder capacity. In some cases, bladder capacity can be increased by providing electrical stimulation to the patient through the stimulator electrode leads described herein. In some cases, the stimulator can provide electrical stimulation of a frequency or pulse width as described elsewhere herein.
[0033] In some cases, the bladder capacity can be increased using an open loop or closed loop system as described elsewhere herein. In some cases, the bladder capacity can be increased by about 5% to about 75%. In some cases, the bladder capacity can be increased by about 5% to about 10%, about 5% to about 15%, about 5% to about 20%, about 5% to about 25%, about 5% to about 30%, about 5% to about 35%, about 5% to about 40%, about 5% to about 45%, about 5% to about 50%, about 5% to about 70%, about 5% to about 75%, about 10% to about 15%, about 10% to about 20%, about 10% to about 25%, about 10% to about 30%, about 10% to about 35%, about 10% to about 40%, about 5% to about 45%, about 5% to about 50%, about 5% to about 70%, about 5% to about 75%, about 10% to about 15%, about 10% to about 20%, about 10% to about 25%, about 10% to about 30%, about 10% to about 35%, about 10% to about 0% to about 40%, about 10% to about 45%, about 10% to about 50%, about 10% to about 70%, about 10% to about 75%, about 15% to about 20%, about 15% to about 25%, about 15% to about 30%, about 15% to about 35%, about 15% to about 40%, about 15% to about 45%, about 15% to about 50%, about 15% to about 70%, about 15% to about 75%, about 20% to about 25%, about 20% to about 30%, about 20% to about 35 %, about 20% to about 40%, about 20% to about 45%, about 20% to about 50%, about 20% to about 70%, about 20% to about 75%, about 25% to about 30%, about 25% to about 35%, about 25% to about 40%, about 25% to about 45%, about 25% to about 50%, about 25% to about 70%, about 25% to about 75%, about 30% to about 35%, about 30% to about 40%, about 30% to about 45%, about 30% to about 50%, about 30% to about 35%, about 30% to about 40%, about 30% to about 45%, about 30% to about 50%, about 30% to about In some cases, bladder capacity can be increased by about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 70%, about 75%, about 40% to 45%, about 40% to 50%, about 40% to 70%, about 40% to 75%, about 45% to 50%, about 45% to 70%, about 45% to 75%, about 50% to 70%, about 50% to 75%, or about 70% to 75%.

In some cases, bladder capacity can be increased by at least about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, or about 70%. In some cases, bladder capacity can be increased by at most about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 70%, or about 75%.
[0034] In some cases, the devices, systems and methods described herein can increase urethral closure pressure. In some cases, urethral closure pressure can be represented by a pressure curve. In some cases, urethral closure pressure can be described as an integrated pressure curve measured from the entire length of the subject's urethra. In some cases, urethral closure pressure can be measured by slowly withdrawing a pressure measurement catheter from the subject's urethra at a constant rate. In some cases, urethral closure pressure can be measured by a transurethral pressure curve (profile) catheter. In some cases, transurethral pressure can be measured in centimeters of water (cm H2O). In some cases, the devices and systems described herein can increase urethral closure pressure by stimulating one or more nerves of the subject. In some cases, one or more nerves can include pudendal nerves, sacral nerves or any combination thereof or their branches.

[0035] The equipment and system described herein may include one or more sensor electrodes, one or more stimulator electrodes, processors, power supplies or any combination thereof. In some cases, one or more stimulator electrodes, one or more sensor electrodes, processors, power supplies or any combination thereof may be implanted in an individual body. In some cases, one or more stimulator electrodes, one or more sensor electrodes, processors, power supplies or any combination thereof may be placed superficially on the body of an individual. In some cases, processors, power supplies or any combination thereof may be implanted in an individual body. In some cases, the equipment may include a wireless transmission module that can be wirelessly transmitted and receive wireless data between a remote device (e.g., a mobile phone, a tablet computer, a computer, etc.) and an incontinence prevention device described herein. In some cases, the equipment may be implanted in an individual. Alternatively, the equipment may include a sealed connector that is placed on the skin surface of an individual and may be electrically connected to a remote device by a cable. In some cases, an individual may manually modify or change one or more sensor electrodes or one or more stimulator electrode parameters by a graphical user interface. In some cases, the equipment may automatically modify or change one or more sensor electrodes or one or more stimulator electrode parameters.
[0036] In some cases, the implanted sensor electrodes of the device may be configured to sense one or more parameters that may be associated with a reaction to an onset of incontinence or an attempt by an individual to prevent an onset of incontinence. In some cases, the parameters may include an electromyographic (EMG) signal that can predict the onset of incontinence. In some cases, the EMG signal may include the electrical activity of the muscle, particularly the action potential from the muscle fiber. In some cases, the parameters may include an electroneurogram (ENG). In some cases, the electroneurogram may include electrical activity from one or more neurons, and generally refers to the recordings made by bundled axons in peripheral nerves. In some cases, the parameters may include changes in electrical impedance caused by physical deformation of the sensor electrode material. In some cases, the physical deformation may include stretching, compression, or any combination thereof. Alternatively, the parameters may include changes in pressure, velocity, acceleration, or three-dimensional spatial direction. In some cases, the three-dimensional spatial direction may be determined by a GPS signal. In some cases, the GPS signal may indicate and identify when an individual is close to a location (e.g., an individual's home). In some cases, the GPS signal may be configured to modulate a stimulator as described elsewhere herein based on the GPS coordinates and / or GPS location of the subject. In some cases, modulating the stimulator can include adjusting the detection parameters (e.g., signal strength threshold) of the classifier as described elsewhere herein. In some cases, the GPS signal and / or GPS coordinates of the location can indicate the location and / or area to which the subject is directed, which may cause a higher risk of incontinence events. In some cases, the three-dimensional spatial direction can measure the posture of the individual. In some cases, the change in pressure can be measured by a pressure sensor. In some cases, the pressure sensor can include a differential pressure sensor, an absolute pressure sensor, or any combination thereof. In some cases, the change in speed, acceleration, or the change in three-dimensional spatial direction can be measured by an accelerometer, a gyroscope, a magnetometer, or any combination thereof. In some cases, the device can provide electrical stimulation using one or more implanted stimulator electrodes, which together with the individual's preventive response can prevent the onset of incontinence.
[0037] The devices, systems, and methods described herein can prevent and / or reduce the severity of incontinence events by detecting individual incontinence prevention parameters and adjusting the electrical stimulation of one or more stimulator electrodes based on the characteristics of the incontinence prevention parameters. In some cases, the incontinence prevention parameter characteristics may include changes in amplitude, frequency, phase, or any combination thereof, changes in one or more EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor signals, or any combination thereof. In some cases, the incontinence prevention parameters may include individual body movements, one or more EMG signals, or any combination thereof. By providing adaptive electrical stimulation in conjunction with individual responses, the devices, systems, and methods described herein can prevent the onset of incontinence.
[0038] This article describes a device, system and method for preventing and / or reducing the severity of an individual's incontinence episode by providing adaptive electrical stimulation based on an individual's incontinence prevention parameters. The device can be implanted in an individual near the pudendal nerve, sacral nerve or their branches. In some cases, one or more stimulator electrodes of the device can be placed at or near the pudendal nerve or sacral nerve. In some cases, one or more stimulator electrodes or one or more sensor electrodes can be implanted near the pudendal nerve unilaterally or bilaterally. In some cases, one or more stimulator electrodes can be implanted to stimulate motor nerve fibers (e.g., to the pelvic floor and sphincter). Alternatively, one or more stimulator electrodes can be implanted in, near or adjacent to a muscle (e.g., the pelvic floor and sphincter). The sensor electrodes of the implanted device can sense a signal indicating that an individual may exhibit an episode of incontinence or attempt to prevent an episode of incontinence. The device can analyze the signal and classify the signal as a real-time or expected episode of incontinence. The device can generate modulated electrical stimulation based on the classified episode of incontinence, and the modulated electrical stimulation can be delivered to the target nerve using one or more stimulator electrodes. In some cases, modulation of the electrical stimulation of one or more stimulator electrodes may include changing the frequency of the electrical stimulation, changing the amplitude of the electrical stimulation, changing the electrical stimulation pulse width, changing the electrode configuration of the stimulator, or any combination thereof. In some cases, one or more electrodes may include one or more stimulator electrodes and one or more sensing electrodes. One or more stimulator electrodes and one or more sensing electrodes may be configured to switch between stimulation and sensing operations as needed, by programming, user control, medical individual control, or any combination thereof. Electrical stimulation may be modulated to improve muscle and / or nerve response to prevent the onset of incontinence. Modulated electrical stimulation may lead to improved muscle response, which is measured by reaction time, muscle function, or other markers of incontinence prevention to prevent the onset of potential incontinence. Electrical stimulation may be modulated to reduce the severity and / or duration of the onset of incontinence. For example, a subject exhibiting an urgency incontinence event (e.g., cough) may receive electrical stimulation provided by the device, system, and method provided herein in response to an incontinence attack. In some cases, electrical stimulation may reduce uncontrolled urination and / or defecation volume. In some cases, electrical stimulation can reduce the amount of uncontrolled urination and / or defecation, without completely preventing the onset of incontinence. In some cases, electrical stimulation can reduce the duration of an incontinence episode that would have occurred without electrical stimulation. In some cases, electrical stimulation can be configured to suppress reflex incontinence. In some cases, electrical stimulation can suppress bladder detrusor contractions experienced during reflex incontinence.
[0039] The electrical stimulation may include electrical stimulation provided over a period of time. In some cases, the period of time may include a period of time during which the subject may provide an intentional or purposeful muscle contraction to trigger an EMG threshold detection.
[0040] In some cases, the time period of electrical stimulation may include about 1 second to about 30 seconds. In some cases, the time period of electrical stimulation may include about 1 second to about 5 seconds, about 1 second to about 10 seconds, about 1 second to about 15 seconds, about 1 second to about 20 seconds, about 1 second to about 25 seconds, about 1 second to about 30 seconds, about 5 seconds to about 10 seconds, about 5 seconds to about 15 seconds, about 5 seconds to about 20 seconds, about 5 seconds to about 25 seconds, about 5 seconds to about 30 seconds, about 10 seconds to about 15 seconds, about 10 seconds to about 20 seconds, about 10 seconds to about 25 seconds, about 10 seconds to about 30 seconds, about 15 seconds to about 20 seconds, about 15 seconds to about 25 seconds, about 15 seconds to about 30 seconds, about 20 seconds to about 25 seconds, about 20 seconds to about 30 seconds, or about 25 seconds to about 30 seconds. In some cases, the time period may include about 1 second, about 5 seconds, about 10 seconds, about 15 seconds, about 20 seconds, about 25 seconds, or about 30 seconds. In some cases, the time period of electrical stimulation can include at least about 1 second, about 5 seconds, about 10 seconds, about 15 seconds, about 20 seconds, or about 25 seconds. In some cases, the time period of electrical stimulation can include up to about 5 seconds, about 10 seconds, about 15 seconds, about 20 seconds, about 25 seconds, or about 30 seconds.

[0042] The present disclosure describes a device for preventing the onset of incontinence, which includes one or more sensor electrodes, one or more stimulator electrodes, an electrical stimulator, or any combination thereof. In some cases, the electrical stimulator may include a processor, a memory, a user interface, a power supply, or any combination thereof for preventing the onset of incontinence. The device may be implantable. The surgical procedure for implanting the device may be performed under conscious sedation, general anesthesia, local anesthesia, morning twilight anesthesia, or any combination thereof. The device may be implanted in whole or in part in the pelvic region of an individual. In some cases, the device may be implanted by one or more surgical instruments. In some cases, the surgical instrument may include an introducer, a sheath, a directable probe, a wire, a needle, or any combination thereof.
[0043] In some cases, the device may further include a transmitter electrically connected to the processor, and the processor may be capable of wirelessly sending and receiving data from a remote device (such as a mobile phone, a tablet computer, or a computer). In some cases, the device may be configured for an open loop configuration. In some cases, the device may be configured as a closed loop configuration or a feedback control configuration. The device described herein may be used to prevent the onset of urinary incontinence. In some cases, urinary incontinence may include urge incontinence, stress incontinence, overflow incontinence, mixed incontinence, or any combination thereof. In some embodiments, the onset of incontinence is urinary incontinence and is an urge incontinence type. In some cases, the device described herein may be used to prevent the onset of fecal incontinence.
[0044] Open loop configuration
[0045] Figure 1 An open-loop configuration of the device described herein is shown for preventing the onset of incontinence in an individual 110. The device in the open-loop configuration may include an implantable pulse generator 102 and a power source, the implantable pulse generator 102 including one or more stimulator electrodes 106. In some cases, the implantable pulse generator 102 may include a processor and a wireless transmission module, the wireless transmission module being configured to execute software to manage the electrical stimulation pattern 104. In some cases, the power source may include a battery. In some cases, the battery may be a lithium polymer ion battery, lithium iodine, lithium manganese dioxide, lithium carbon monofluoride, or any combination thereof. In some cases, the battery may be wirelessly charged via an inductive charger. Alternatively, the battery power source may be disposable.
[0046] The implantable pulse generator 102 can provide a predefined electrical stimulation pattern 104 set by a healthcare provider on a remote device 100 (e.g., a mobile phone, tablet computer, etc.) and wirelessly transmitted 105 to the implantable pulse generator 102. Alternatively, the implantable pulse generator 102 can provide a predefined electrical stimulation pattern 104 set by a healthcare provider on a remote computer device 100 (e.g., a mobile phone, tablet computer, etc.) and transmitted to the implantable pulse generator 102 via wired communication 101. In some cases, the healthcare provider can set the predefined electrical stimulation parameters through a graphical user interface on the remote device. In some cases, the individual 110 with the implantable pulse generator 102 can modify or set the electrical stimulation parameters via an external input device 103 (e.g., a mobile phone, tablet computer, etc.) via wireless communication 105 of the implantable pulse generator 102. Alternatively, the individual 110 with the implantable pulse generator 102 can modify or set the electrical stimulation parameters via an external input device 103 via wired communication 107 of the implantable pulse generator 102. In some cases, individual 110 with implanted pulse generator 102 can adjust electrical stimulation pattern 104 using a graphical user interface on external input device 103. In some cases, electrical stimulation pattern 104 parameters that can be adjusted include frequency, amplitude, pulse width, or any combination thereof.
[0047] Closed loop configuration
[0048] Figure 2A closed-loop configuration of a device described herein configured to prevent the onset of incontinence of an individual 126 is shown. The device in the closed-loop configuration may include an implantable pulse generator 118, one or more stimulator electrodes 122, one or more sensor electrodes 120, and a power source. In some cases, the implantable pulse generator 118 may include a processor and a wireless transmission module, and the wireless transmission module is configured to execute software to detect, analyze myoelectric (EMG) signals and manage electrical stimulation patterns 124 via one or more sensor electrodes 120. In some cases, the power source may include a battery. The battery may be rechargeable or disposable. In some cases, the battery may be charged by inductive charging. In some cases, a device configured as a closed-loop configuration may measure EMG signals via one or more sensor electrodes 120 to detect the onset of a stress incontinence event or the level of innate myoelectric activity. In some cases, a device configured as a closed-loop configuration may measure inertial signals (e.g., rapid acceleration, shock, posture orientation, or any combination thereof) via one or more sensor electrodes 120 to detect the onset of a stress incontinence event or the level of innate myoelectric activity. In some cases, stress incontinence events may include actions such as coughing, sneezing, laughing, or exercising. Once detected, implantable pulse generator 118 may provide electrical stimulation pattern 124 to prevent urination or uncontrolled bowel movements. In some cases, the threshold level for detecting stress incontinence events may be modified and adjusted by individual 126 via a graphical user interface on external input device 114 or via wireless communication 113 or wired connection 115.
[0049] In some embodiments, a closed-loop configuration of the systems and methods described herein may include a fully synchronized system, such as Fig. 9 As shown. In some cases, electrodes 902 including sensor and / or stimulator electrodes can detect EMG, ENG, and / or pressure signals through circuit 904 (e.g., analog-to-digital circuit), and the detected signals can then be passed to a classifier algorithm 906. Once the classifier algorithm 906 has classified the detected EMG, ENG, and / or pressure signals as an incontinence event, the classifier can enable electrical stimulation 908 to be delivered to the patient. Fig. 9 As shown, electrical stimulation may be provided by the same electrodes 902 from which the EMG and / or ENG signals were initially sensed.
[0050] In some embodiments, the closed-loop configuration of the device described herein can be configured to detect the efforts made by an individual in an attempt to prevent the onset of incontinence. In some cases, the methods and systems described herein can supplement the patient's efforts with an electrical stimulation pattern sufficient to prevent urination or defecation via one or more stimulator electrodes 122. In some cases, the individual's efforts can include signals of EMG, ENG, pressure, acceleration, gyroscope, magnetometer, three-dimensional space, or any combination thereof at a threshold. In some cases, the threshold electromyographic signal can be detected by one or more sensor electrodes 120. In some cases, supplementary stimulation can include a stimulation signal provided by a stimulator electrode as described elsewhere herein, the stimulation signal having parameters (e.g., frequency, pulse width, and / or amplitude) so as to combine with the individual's efforts detected to prevent the onset of incontinence (e.g., urination and / or defecation). In some cases, supplementary stimulation can include a stimulation signal provided by a stimulator electrode, the stimulation signal having parameters (e.g., frequency, pulse width, and / or amplitude) to prevent the onset of incontinence in response to detecting a stress incontinence event. In some cases, a stress incontinence event may include an action (e.g., coughing, sneezing, laughing, or exercising) that may be detected by, for example, a gyroscope, accelerometer, and / or magnetometer as described elsewhere herein. In some cases, one or more parameters of the supplemental stimulation may be determined on an individual subject basis and / or on a large population of subjects with similar incontinence presentations. For example, given a subject's supplemental stimulation, one or more parameters may be adjusted and / or determined by a user interface of a device and system as described elsewhere herein based on whether such a supplemental stimulation signal prevents the onset of incontinence in real time or after an incontinence event. In some cases, given a subject's supplemental stimulation, one or more parameters may be adjusted to values and / or parameters found in subjects with similar clinical presentations to prevent incontinence events (e.g., age, type of incontinence, frequency of incontinence events, other subject clinical metadata, etc.).
[0051] In some cases, the systems and methods described herein may include systems and methods configured to provide electrical stimulation based on purposeful muscle contraction and / or movement of a subject and / or patient to prevent an incontinence event, such as Figure 8As shown. In some cases, the subject and / or patient 814, upon realizing that they may exhibit an incontinence event, may induce movement and / or contraction of one or more muscles or muscle groups to trigger a signal 818 of EMG, ENG, pressure, acceleration, gyroscope, magnetometer, three-dimensional space, or any combination thereof. In some cases, the induced movement and / or contraction of one or more muscle groups may be amplified 808, classified (by a classifier) 806, by a control logic algorithm 804, and used as a trigger 820 to enable treatment and corresponding stimulation pattern parameters of the basic 802 and / or active 801 as described elsewhere herein to flow through the stimulator 810 and the neural interface 812 to prevent incontinence events. In some cases, the classifier may include a machine learning classifier. In some cases, the classifier may include an intensity threshold classifier as described elsewhere herein. In some cases, the patient and / or subject 814 may manually 816 enable electrical stimulation to be provided via a button on the patient controller module 156 as described elsewhere herein.
[0052] In some cases, the detection threshold of the implantable pulse generator 118 (i.e., stimulator) can be modified and adjusted via a graphical user interface on the external input device 114. The external input device 114 is capable of modifying and adjusting the threshold of the implantable pulse generator 118 via wireless communication 113 or wired connection 115. In some cases, the threshold of the implantable pulse generator can be adjusted via a healthcare provider on a remote computing device 112 (e.g., a mobile phone, tablet, computer, etc.) and transmitted to the implantable pulse generator 118 via wired communication 116. Alternatively, the threshold of the implantable pulse generator can be adjusted via a healthcare provider on a remote computing device 112 (e.g., a mobile phone, tablet, computer, etc.) and transmitted to the implantable pulse generator 118 via wireless communication 113. In some cases, the threshold of the implantable pulse generator can be adjusted via the individual 110 on a remote computing device 112 (e.g., a mobile phone, tablet, computer, etc.) and transmitted to the implantable pulse generator 118 via wired communication 116. Alternatively, the threshold of the implantable pulse generator may be adjusted by the individual 110 on a remote computing device 112 (eg, a mobile phone, tablet, computer, etc.) and transmitted to the implantable pulse generator 118 via wireless communication 113 .
[0053] In some cases, the electrical stimulation pattern 124 provided via one or more stimulator electrodes 122 can be adjusted and adjusted by the detected threshold level to supplement the individual's efforts to prevent the onset of incontinence. In some cases, the adjusted electrical stimulation pattern 124 can be determined by mapping the detectable physiological signal representing the effort and the provided electrical stimulation pattern 124 through a piecewise linear mapping, a linear mapping, an S-shaped mapping, or any variation thereof. The electrical stimulation pattern 124 can be adjusted by modifying or changing the electrical stimulation pattern parameters including frequency, pulse width, and amplitude. In some cases, the electrical stimulation pattern parameters of the implantable pulse generator 118 can be modified and adjusted via a graphical user interface on an external input device 114. The external input device 114 is capable of modifying and adjusting the electrical stimulation pattern parameters of the implantable pulse generator 118 via wireless communication 113 or a wired connection 115. In some cases, the electrical stimulation pattern parameters of the implantable pulse generator 118 can be adjusted by a healthcare provider on a remote computing device 112 (e.g., a mobile phone, a tablet computer, a computer, etc.) and transmitted to the implantable pulse generator 118 via wired communication 116. In some cases, the electrical stimulation pattern parameters of the implantable pulse generator 118 can be adjusted via a healthcare provider on a remote computing device 112 (e.g., a mobile phone, tablet, computer, etc.) and transmitted to the implantable pulse generator 118 via wireless communication 113. In some cases, the electrical stimulation pattern parameters of the implantable pulse generator 118 can be adjusted based on input from the individual 126 by a machine learning model executed by a processor of the implantable pulse generator 118. In some cases, the machine learning model can be configured to determine whether the subject is at risk of unwanted urination and / or defecation based on muscle EMG signals detected by one or more sensor electrodes. In some cases, the machine learning model can be trained to determine whether the individual's efforts exist, as described elsewhere herein. For example, the machine learning model can be trained with one or more EMG signal features of the subject's muscle contraction (particularly EMG signals that cause unwanted urination and / or defecation).
[0054] In some embodiments, electrical stimulation pattern parameters (e.g., frequency, amplitude, etc.) as described elsewhere herein may be set or determined by a stimulation machine learning model. In some cases, the stimulation machine learning model may include a Bayesian optimization model. In some cases, the stimulation machine learning model may be trained with a stimulation pattern that is indicated by a user of the device and system described elsewhere herein as suppressing incontinence events of a particular type and / or subtype of incontinence. In some cases, the stimulation machine learning model may be trained with a patient incontinence type. The stimulation machine learning algorithm may be trained in a cloud computing network and / or server that communicates with an implanted device and a user device, as described elsewhere herein, and redistributed or downloaded to one or more users and / or patients. In fact, users and / or patients may update and / or download new updates to the software of the device and system described herein. This aspect of the invention described herein provides the unexpected result of patient-specific and optimized electrical stimulation signals that cannot be achieved with conventional stimulators.
[0055] One or more machine learning algorithms can be used to construct a machine learning model, such as a support vector machine that deploys stepwise backward parameter selection and / or a graphical model, both of which can have the advantage of inferring the interaction between parameters. For example, a machine learning algorithm or other statistical algorithm can be used, such as alternating decision trees (ADTree), decision trees, functional trees (FT), logistic model trees (LMT), logistic regression, random forests (RF), receiver operating characteristic curves (ROC), linear regression, extreme gradient boosting (XGB), classification and regression trees, support vector machines (SVM), generalized additive models using spline functions (e.g., gamSpline), glmnet, multivariate adaptive regression splines (splint) (earth), neural networks, k-means clustering, or any machine learning algorithm or statistical algorithm known in the art. One or more algorithms may be used together to generate an ensemble method, wherein the ensemble method may be optimized using a machine learning ensemble meta-algorithm, such as a boosting method (e.g., AdaBoost, LPBoost, TotalBoost, BrownBoost, MadaBoost, and LogitBoost, etc.) to reduce bias and / or variance.
[0056] In some embodiments, the machine learning algorithm may include a restricted machine learning algorithm configured to run on a microprocessor. In some cases, the machine learning algorithm may include a machine learning algorithm operating within a TinyML framework. In some cases, the machine learning algorithm described elsewhere herein may be trained offline. Offline training may be completed on a server, cloud, or other dedicated computing cluster. In some cases, the offline trained machine learning algorithm may then be downloaded, deployed, and / or imported into the device to iteratively improve the performance of the device and system in preventing incontinence events.
[0057] A person of ordinary skill will appreciate that such an offline training structure is feasible and implemented in related but different implementations. For example, this machine learning architecture can be used to perform "wake-up word" text classification commonly found in smartphone devices (e.g., "Hey, Siri", "OK, Google", etc.). In some cases, the machine learning algorithms described herein can operate within a framework similar to a "wake-up word" voice machine learning classifier. In some cases, the machine learning algorithms described herein can operate based on processing power and storage allocations determined to be sufficient to "wake up" a voice machine learning classifier.
[0058] In some cases, the software described elsewhere herein can be executed by a processor located on an implanted stimulator. In some cases, the software located on the implanted stimulator can utilize the TinyML constraint machine learning model to adapt the processing and memory parameters of the implanted stimulator. In some cases, the software can be executed offline on cloud-based computing and / or dedicated computing clusters. In some cases, the offline processing workflow can include high-speed (Bluetooth, Wi-Fi, medical implant communication system, etc.) data transmission between the implanted stimulator and a local individual computing device (smart phone, tablet computer, laptop computer, etc.). Then, the individual processing device can transfer the implanted stimulator data to one or more clouds and / or computer clusters, and then the result output, command and / or notification are sent back to the device. In some cases, commands and / or notifications can include warnings, alarms, the start of electrical stimulation, or any combination thereof. In some cases, a command can include the output of a machine learning classifier configured to determine the threshold intensity of an EMG and / or ENG signal indicating an incontinence event.
[0059] The machine learning model can be trained on one or more data sets. In some cases, the one or more data sets may include data generated by users and / or subjects, or data generated by a group or a fragment thereof. In some cases, the subject-generated data and / or the group-generated data may include effort signals, stimulation signals indicating incontinence events and preventing incontinence events, respectively. In some cases, the devices, systems, and corresponding methods described herein may record user data and / or user input when interacting with the systems and devices described elsewhere herein. In some cases, the data may include sensors such as EMG, ENG, accelerometer, gyroscope, or any combination thereof that are user-marked as described elsewhere herein that lead to incontinence events. In some cases, these signals can be obtained from the device 1302 and used to characterize 1304 and train the machine learning classifier 1306, such as Fig.13 As shown. In some cases, a trained machine learning classifier trained on one or more data sets can then be downloaded to each patient's device 1308 to further improve the accuracy of the machine learning classifier. In some cases, the machine learning model can be configured to sense the subject's efforts and / or provide sufficient stimulation based on the parameters of frequency, amplitude and / or pulse width, as described elsewhere herein. In some cases, one or more individual data sets can be pooled together as a training data set, in which the subject shows features of similarities between the parameters of clinical manifestations and excitement / sensory input. In some cases, clinical manifestations can include clinical incontinence types, subject clinical metadata (e.g., sex, age, past medical history, current medications, past surgical interventions, etc.). In some cases, during the initial stage of training the device implanted in the subject, a pooled training data set can be used for the individual.
[0060] In some cases, one or more machine learning models as described elsewhere herein can be trained based on raw and / or processed signals measured by the devices, sensors, and systems described elsewhere herein. In some cases, the processed signal can include the raw signal that has been filtered to optimize the signal-to-noise ratio of the raw signal. In some cases, the filter can include a high pass, low pass, band pass, notch, or any combination thereof. In some cases, one or more machine learning models can alternatively or additionally be trained based on user feedback about previous stimulation signal parameters and whether such stimulation signal parameters prevented incontinence events.

[0064] In some cases, the amplified signal can then be passed to filter 1004. In some cases, the filter can include a low pass, high pass, band pass, notch, or any combination thereof.
[0065] In some cases, the filter can be configured to filter a frequency band of about 1 Hz to about 70 Hz. In some cases, the filter can be configured to filter a frequency band of about 1 Hz to about 5 Hz, about 1 Hz to about 10 Hz, about 1 Hz to about 15 Hz, about 1 Hz to about 20 Hz, about 1 Hz to about 25 Hz, about 1 Hz to about 40 Hz, about 1 Hz to about 50 Hz, about 1 Hz to about 60 Hz, about 1 Hz to about 70 Hz, about 5 Hz to about 10 Hz, about 5 Hz to about 15 Hz, about 5 Hz to about 20 Hz, about 5 Hz to about 25 Hz, about 5 Hz to about 40 Hz, about 5 Hz to about 50 Hz, about 5 Hz to about 60 Hz, about 5 Hz to about 70 Hz, about 10 Hz to about 15 Hz, about 10 Hz to about 20 Hz, about 10 Hz to about 25 Hz, about 10 Hz to about 40 Hz, about 10 Hz to about 50 Hz, about 10 Hz to about 60 Hz , about 10 Hz to about 70 Hz, about 15 Hz to about 20 Hz, about 15 Hz to about 25 Hz, about 15 Hz to about 40 Hz, about 15 Hz to about 50 Hz, about 15 Hz to about 60 Hz, about 15 Hz to about 70 Hz, about 20 Hz to about 25 Hz, about 20 Hz to about 40 Hz, about 20 Hz to about 50 Hz, about 20 Hz to about 60 Hz, about 20 Hz to about 70 Hz, about 25 Hz to about 40 Hz, about 25 Hz to about 50 Hz, about 25 Hz to about 60 Hz, about 25 Hz to about 70 Hz, about 40 Hz to about 50 Hz, about 40 Hz to about 60 Hz, about 40 Hz to about 70 Hz, about 50 Hz to about 60 Hz, about 50 Hz to about 70 Hz, or about 60 Hz to about 70 Hz. In some cases, the filter can be configured to filter a frequency band of about 1 Hz, about 5 Hz, about 10 Hz, about 15 Hz, about 20 Hz, about 25 Hz, about 40 Hz, about 50 Hz, about 60 Hz, or about 70 Hz. In some cases, the filter can be configured to filter a frequency band of at least about 1 Hz, about 5 Hz, about 10 Hz, about 15 Hz, about 20 Hz, about 25 Hz, about 40 Hz, about 50 Hz, or about 60 Hz.

[0066] After passing the signal through the filter, the systems and methods described herein can rectify the filtered signal 1006. In the process of rectifying the signal, as will be understood by one of ordinary skill in the art, the signal will convert the AC detection signal into a DC signal. The rectified signal can be additionally filtered with a low pass filter 1007 that can smooth the rectified signal. The signal can be subjected to a threshold detector 1008, where the threshold detector 1008 determines the onset of an incontinence event based on a threshold intensity value of the rectified and smoothed signal 1000 of the EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor signal, or any combination thereof. If an incontinence event is determined by the threshold detector 1008, the system can effectuate the delivery of electrical stimulation 1010, as described elsewhere herein.
[0067] In some cases, the training may be supervised training. Alternatively, the training may be unsupervised training. In some cases, the data set may be a retrospective data set. Alternatively, the data set may be a prospectively developed data set, and the machine learning model may be iteratively improved over time.
[0068] In some aspects, the disclosure provided herein may include a method for training a machine learning model with a data set including sensed signal profiles of prevented and unprevented incontinence events and stimulation signals. The method may include the following steps: preprocessing, training, and prediction.
[0069] The method can extract training data from a database, or introduce new data, as described elsewhere in this article. The preprocessing step can apply one or more transformations to standardize the training data or new data used for the training step or prediction step. The preprocessed training data can be passed to a training step that can build a machine learning model based on the training data. The training step can further include a validation step, which is configured to use any suitable validation algorithm (e.g., stratified K-fold cross validation) to validate the trained machine learning model. In some cases, K-fold cross validation can include at least 1 fold, 2 fold, 3 fold, 4 fold, 5 fold, 6 fold, 7 fold, 8 fold, 9 fold or 10 fold. In some cases, k-fold cross validation can include up to 1 fold, 2 fold, 3 fold, 4 fold, 5 fold, 6 fold, 7 fold, 8 fold, 9 fold or 10 fold.
[0070] The preprocessing step may apply one or more transformations to the training data to clean and normalize the data. The preprocessing step may be configured to discard parameters that contain spurious data or contain very few observations. The preprocessing module may further be configured to standardize the encoding of parameter values. The preprocessing step may identify encoding variations for the same value and normalize the data set to have a uniform encoding for a given parameter value. Thus, the processing step may reduce irregularities in the input data for the training and prediction steps, thereby improving the robustness of the training and prediction stages.
[0071] The training step can utilize a machine learning algorithm or other algorithm to construct and train a machine learning model for stimulation stimulus, sensed signal profile, and the presence or absence of an incontinence event. The machine learning model can be constructed to capture the statistical relationship (if any) between the stimulation stimulus parameters, the sensed signal profile, and the presence or absence of an incontinence event based on the training data.
[0072] The accuracy of the machine learning algorithm can be greater than about 60%, 70%, 80%, 85%, 90%, 95%, or 99%. The positive prediction value of the machine learning algorithm can be greater than about 60%, 70%, 75%, 80%, 85%, 90%, 95%, or 99%. The negative prediction value of the machine learning algorithm can be greater than about 60%, 70%, 80%, 90%, 95%, or 99%.
[0073] Machine learning data analysis, machine learning model training, or any combination thereof can be performed using one or more of many programming languages and platforms known in the art, such as R, Weka, Python, and / or MATLAB.
[0074] The use of such a closed-loop bioelectronic system can potentially provide an improved electrical stimulation device to prevent or reduce stress incontinence. In some cases, the use of such a closed-loop bioelectronic system can provide a more accurate method to prevent or reduce or treat urge incontinence and mixed incontinence (a combination of urge and stress incontinence). In some cases, an individual with an implanted device can provide feedback on the positive results, negative results, or neutral results provided by the parameters. In some cases, a positive result may include preventing an incontinence event. In some cases, a negative result may include not preventing an incontinence event, producing pain, or any combination thereof. In some cases, a neutral result may include not preventing an incontinence event, not producing pain, or any combination thereof. In some cases, positive results, negative results, neutral results, sensor data, or any combination thereof from multiple individuals with an implanted device can be used to adjust the algorithm to suggest changes in sensor electrode thresholds and electrical stimulation patterns 124.
[0075] Electrical stimulation mode
[0076] In some cases, the electrical stimulation pattern provided by the implantable pulse generator and one or more stimulator electrodes can be modified or changed to adapt to the needs of individuals in need, thereby preventing the onset of incontinence. In some cases, one or more stimulator electrodes 122 can output an electrical stimulation pattern 124 in response to the content detected by one or more sensor electrodes 120. In some cases, the electrical stimulation pattern 124 may include one or more electrical signals. For example, the electrical stimulation pattern 124 may include a continuous wave signal (e.g., an electrical stimulation signal with a constant frequency in time) and a burst or beating signal superimposed on the continuous wave signal. In some cases, the burst or beating signal can be enabled only in a short duration compared to the continuous time aspect of the continuous wave signal. In some cases, the combination of a continuous wave signal and / or a burst or beating signal can increase the pain threshold of the subject to allow the stimulator to provide a higher amplitude electrical stimulation burst pattern to prevent incontinence events. In some cases, the frequency of the electrical stimulation pattern can be modified or changed. The frequency pattern may include a constant profile, a sweep profile, a beating profile, a burst profile, a chirped profile, a single-phase profile, a biphasic profile, or any combination thereof. In some cases, the constant profile is composed of an excitation value of a constant amplitude with a frequency value of 0Hz. In some cases, the sweep profile may include a signal with a time-varying excitation frequency. In some cases, the beating profile may include a combination of one or more excitation signals of varying frequencies. In some cases, the burst profile may include a signal with a constant frequency enveloped by an envelope function of square, delta, sine or any combination thereof. In some cases, the single-phase profile may include an excitation signal (e.g., a signal with a value from 0 to -5V or only from 0 to 5V) with a constant frequency that has only positive or negative amplitude. In some cases, the beating or burst profile may include an electrical simulation mode that is provided to a patient and / or subject during the on state of a first time period, and is not provided to a patient and / or subject during the off state of a second time period. In some cases, the beating or burst profile may provide an excitation signal that can provide longer muscle stimulation without suffering muscle fatigue. In some cases, the on state and / or the off state may include about 0.1 seconds to about 6.5 seconds.In some cases, the on state and / or the off state may include about 0.1 seconds to about 0.5 seconds, about 0.1 seconds to about 1 second, about 0.1 seconds to about 1.2 seconds, about 0.1 seconds to about 1.5 seconds, about 0.1 seconds to about 2 seconds, about 0.1 seconds to about 2.5 seconds, about 0.1 seconds to about 3 seconds, about 0.1 seconds to about 3.5 seconds, about 0.1 seconds to about 4 seconds, about 0.1 seconds to about 5 seconds, about 0.1 seconds to about 6.5 seconds, about 0.5 seconds to about 1 second, about 0.5 seconds to about 1.2 seconds, about 0.5 seconds to about 1.5 seconds. seconds, about 0.5 seconds to about 2 seconds, about 0.5 seconds to about 2.5 seconds, about 0.5 seconds to about 3 seconds, about 0.5 seconds to about 3.5 seconds, about 0.5 seconds to about 4 seconds, about 0.5 seconds to about 5 seconds, about 0.5 seconds to about 6.5 seconds, about 1 second to about 1.2 seconds, about 1 second to about 1.5 seconds, about 1 second to about 2 seconds, about 1 second to about 2.5 seconds, about 1 second to about 3 seconds, about 1 second to about 3.5 seconds, about 1 second to about 4 seconds, about 1 second to about 5 seconds, about 1 second to about 6.5 seconds, about 1.2 seconds to about 1 .... 1.2 seconds to about 2 seconds, about 1.2 seconds to about 2.5 seconds, about 1.2 seconds to about 3 seconds, about 1.2 seconds to about 3.5 seconds, about 1.2 seconds to about 4 seconds, about 1.2 seconds to about 5 seconds, about 1.2 seconds to about 6.5 seconds, about 1.5 seconds to about 2 seconds, about 1.5 seconds to about 2.5 seconds, about 1.5 seconds to about 3 seconds, about 1.5 seconds to about 3.5 seconds, about 1.5 seconds to about 4 seconds, about 1.5 seconds to about 5 seconds, about 1.5 seconds to about 6.5 seconds, about 2 seconds to about 2.5 seconds, about 2 seconds to about 3 seconds, about 2 seconds to about 3.5 seconds, In some cases, the on state and / or the off state can include about 0.1 seconds, about 0.5 seconds, about 1 second, about 1.2 seconds, about 1.5 seconds, about 2 seconds, about 2.5 seconds, about 3 seconds, about 3.5 seconds, about 4 seconds, about 2.5 seconds to about 5 seconds, about 2.5 seconds to about 6.5 seconds, about 3 seconds to about 3.5 seconds, about 3 seconds to about 4 seconds, about 3 seconds to about 5 seconds, about 3 seconds to about 6.5 seconds, about 3.5 seconds to about 4 seconds, about 3.5 seconds to about 5 seconds, about 3.5 seconds to about 6.5 seconds, about 4 seconds to about 5 seconds, about 4 seconds to about 6.5 seconds, about 5 seconds to about 6.5 seconds. In some cases, the on state and / or the off state can include about 0.1 seconds, about 0.5 seconds, about 1 second, about 1.2 seconds, about 1.5 seconds, about 2 seconds, about 2.5 seconds, about 3 seconds, about 3.5 seconds, about 4 seconds, about 5 seconds or about 6.5 seconds. In some cases, the on state and / or the off state may include at least about 0.1 seconds, about 0.5 seconds, about 1 second, about 1.2 seconds, about 1.5 seconds, about 2 seconds, about 2.5 seconds, about 3 seconds, about 3.5 seconds, about 4 seconds, or about 5 seconds. In some cases, the on state and / or the off state may include at most about 0.5 seconds, about 1 second, about 1.2 seconds, about 1.5 seconds, about 2 seconds, about 2.5 seconds, about 3 seconds, about 3.5 seconds, about 4 seconds, about 5 seconds, or about 6.5 seconds.
[0077] In some cases, the electrical stimulation pattern provided during the on state may include an oscillating electrical stimulation pattern. In some cases, the oscillating electrical stimulation pattern may include one or more frequencies. In some cases, the frequency of the oscillating electrical stimulation can be selected based on a priori knowledge of how similar subjects react to a specific frequency or frequency range of the oscillating electrical stimulation pattern. In some cases, low frequencies (e.g., 2 Hz to 15 Hz) can cause a decrease in bladder contractility, thereby preventing urination or potential incontinence events. In some cases, higher frequencies (e.g., 20 Hz to 50 Hz) can result in enhanced bladder contraction and urination.

In some cases, one or more leads described elsewhere herein may be sterilized with conventional sterilization methods used in the medical field (e.g., gas sterilization, steam sterilization, ultraviolet sterilization, etc.).
[0093] In some cases, one or more leads described elsewhere herein can be electrically connected to an electrical stimulator described elsewhere herein. In some cases, one or more leads can be connected to a stimulator and can be disconnected from the stimulator at a later point in time. In some cases, one or more leads can be connected to an electrical stimulator with a quick release electrical connection. In some cases, one or more leads can be connected to an electrical stimulator by a set screw fastener, thereby inserting the lead into a hollow cylindrical geometry that is electrically connected to the internal circuit of the electrical stimulator. The lead can then be fixed to the conductive hollow cylindrical geometry with a non-conductive machine set screw, that is, the lead is pressed against the inner wall of the hollow cylindrical geometry. One or more leads can be placed in the electrical stimulator before or during a surgical implantation procedure.
[0094] In some cases, the sensor electrodes and stimulator electrodes are operably connected to a processor and a non-transitory computer readable medium including software. In some cases, the sensor electrodes can be calibrated by an individual using an external input device that interfaces with the software. In some cases, the software can be configured to record signals from the sensor electrodes. In some cases, the software can be configured to adjust the sensor electrodes in response to the signals.
[0095] In some cases, the stimulator electrode may provide electrical stimulation to the pudendal nerve. In some cases, the stimulator electrode may provide electrical stimulation to the sacral nerve. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the pelvic muscles. In some cases, the electrode may include one or more electrodes or leads, such as a first and a second electrode. In some cases, the electrode may include one or more stimulator electrodes. In some cases, the electrode may include a first stimulator electrode and a second stimulator electrode, the first stimulator electrode being configured to stimulate a pudendal nerve, and the second stimulator electrode being configured to stimulate another spatially independent region of the same pudendal nerve. In some cases, the first stimulator electrode may stimulate the trunk of the pudendal nerve, and the second stimulator electrode may stimulate the distal nerve of the pudendal nerve. In some cases, the distal nerve of the pudendal nerve includes a branch of the distal pudendal nerve. In some cases, the first stimulator electrode may stimulate the trunk of the pudendal nerve, and the second stimulator electrode may stimulate the main branch of the pudendal nerve (e.g., the dorsal genital nerve). In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the urethral sphincter. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the urethra. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the bladder. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the ureter. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the anal sphincter. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the anus. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the rectum. In some cases, the stimulator electrode may provide electrical stimulation to one or more nerves that innervate the bowel. In some cases, the device described herein may include multiple stimulator electrodes. In some cases, the device described herein may include one or more stimulator electrodes. In some cases, the device described herein may include different stimulator electrodes or a second stimulator electrode. In some cases, the stimulator electrode may stimulate a first pudendal nerve, while a different stimulator electrode or a second stimulator electrode stimulates a second pudendal nerve. In some cases, the stimulator electrode may stimulate a first sacral nerve, while a different stimulator electrode or a second stimulator electrode stimulates a second sacral nerve.
[0096] In some cases, the stimulator electrodes of the device can provide constant electrical stimulation. In some cases, the stimulator electrodes of the device can provide constant electrical stimulation at a lower intensity level than the electrical stimulation provided to prevent the onset of incontinence. In some cases, the constant electrical stimulation may include a constant frequency, amplitude, current, or any combination thereof. In some cases, the intensity or duration of the electrical stimulation provided can prevent the onset of incontinence, which varies according to the individual's response to the onset of possible incontinence sensed by the sensor electrodes. In some cases, the individual's response to prevent possible incontinence attacks sensed by the sensor electrodes may not be sufficient to prevent the onset of incontinence, and the electrical stimulation provided by the stimulator electrodes of the device provides sufficient stimulation, together with the response, to prevent the onset of incontinence. In some cases, the individual's response to prevent possible incontinence attacks sensed by the sensor electrodes is combined with the electrical stimulation provided by the stimulator electrodes of the device, providing sufficient stimulation to trigger the action potential of the muscle that causes incontinence, resulting in muscle contraction. In some cases, the combined stimulation from the individual and the device can cause muscle contraction. In some cases, the muscle may include the urethral sphincter. In some cases, the muscle may include the anal sphincter. In some cases, the muscle may include one or more pelvic floor muscles.
[0097] In some cases, the sensor electrode can include a housing and leads. In some cases, the housing can be made of titanium or a titanium alloy. In some cases, the leads can be made of a metal alloy.
[0098] Device Anchors
[0099] In some cases, when implanted by one or more surgical instruments, the device can be anchored. In some cases, the anchoring of the device can be achieved by sliding the device on the lead, as described elsewhere in this article, and then using a bandage (ligatures) to squeeze it onto the lead so that it is fixed. These bandages can be used to fix the anchoring device to native adjacent tissue (native adjacent tissue) (such as ligaments or periosteum). In some cases, the device can include a groove for aligning the extrusion bandage. In some cases, the anchoring device may include a torque system to squeeze the device onto the lead so that it is fixed. In some cases, the device can be squeezed on the lead at a single point. In some cases, the device is squeezed on the lead at two or more points. The electrical stimulator may include a radiopaque marker, which may allow the electrical stimulator to be visualized under x-rays (such as fluoroscopy) during and / or after implantation. In some cases, fluoroscopy can be used alone or in combination with the EMG sensor electrode readings of the pelvic floor muscles to verify or adjust the placement of the sensor electrode lead, stimulator electrode lead and / or stimulator.
[0100] electric signal
[0101] Figure 4 Sensed myoelectric EMG signals and corresponding electrical stimulation ("biostimulators") provided by the devices disclosed herein are described. In some cases, the myoelectric EMG signals ("biosignals") 140 may include electrical fluctuations 142 corresponding to contraction activity of muscles near the sensor electrodes. In some cases, the electrical fluctuations 142 may represent coughs, sudden movements, inertia changes, or any combination thereof from electromyogram (EMG) readings. In some cases, the biosignals captured by the sensor electrodes may be analyzed and classified 144 to identify any stress events (e.g., coughs or sudden movements) based on the EMG readings. In some cases, the identified stress event may initiate a process 146, through which an implantable electrical stimulator may provide an electrical stimulation pattern 148 to one or more pudendal nerves via one or more stimulator electrodes to prevent the onset of incontinence. In some cases, the stimulator electrode may deliver electrical stimulation via one or more stimulator electrodes 122, which is configured to supplement the innate reflexes detected by one or more sensor electrodes 120 to explain stress events that otherwise cause incontinence events.

[0109] In some cases, the electrical stimulator can be sterilized using conventional sterilization methods used in the medical field (e.g., gas sterilization, steam sterilization, ultraviolet sterilization, etc.).
[0110] In some cases, one or more stimulator electrodes can provide constant electrical stimulation, or basal stimulation 146 and 150, to individuals experiencing urge incontinence. In some cases, the constant electrical stimulation can include a constant frequency, amplitude, current, or any combination thereof. In some cases, the stimulator electrodes can provide temporary electrical stimulation for the duration of an episode of stress incontinence 148 to individuals experiencing stress incontinence. In some cases, the stimulator electrodes can provide constant electrical stimulation (i.e., basal stimulation mode) with temporary activation stimulation (i.e., activation stimulation mode) for the duration of an episode of stress incontinence to individuals experiencing mixed incontinence.
[0111] In some cases, the device disclosed herein may include a non-transitory computer-readable medium including software. In some cases, the software may be configured to record a signal from one or more sensor electrodes. In some cases, the software may be configured to process a recorded signal from one or more sensor electrodes to determine whether it is necessary to provide an electrical stimulation pattern to one or more stimulator electrodes that dominate one or more pudendal nerves. In some cases, the software may be configured to adjust the parameters of the sensor electrodes in response to the observed signal. In some cases, the recorded signal of the sensor electrode by the software can observe a signal that saturates the dynamic range of the sensor electrode. In some cases, the gain of the sensor electrode can be adjusted by software to allow the myoelectric EMG signal of an individual to be fully monitored and thresholded.
[0112] Using a device for neurostimulation
[0113] Figure 3 An exemplary embodiment of the devices and methods described herein implanted in an individual is shown. In some cases, the implanted device can target the pudendal nerve 133 by placing sensor electrodes 134 and 136 and stimulation electrodes near the pudendal nerves 130 and 132. The sensor electrodes 134 and 136 can capture biosignals to classify any stress events, and the stimulator electrodes 130 and 132 can provide pressure electrical stimulation ("biosimulator") to act on the target sphincter, which is adjusted according to the basal stimulation to respond to the stress event.
[0114] In some cases, providing electrical stimulation to the pudendal nerve rather than the sacral nerves may provide greater precision because the pudendal nerve or its branches are inferior to the sacral nerves and closer to organs and tissues involved in incontinence than the sacral nerves. The device's sensor electrodes capture biosignals to classify any stressful events, and the device's stimulator electrodes provide pressure electrical stimulation ("biosimulator") to act on the target sphincter, which is adjusted based on the basal stimulation to respond to the stressful event.
[0115] Neurostimulation systems for managing incontinence
[0116] Figure 5 An exemplary embodiment of a system block diagram for the apparatus and methods described herein utilizing slow and fast adaptive algorithms is shown.

The method may include the following steps: (a) implanting sensor electrodes and stimulator electrodes 218 in the body of the individual; (b) sensing parameters associated with a response from the individual for preventing an onset of incontinence 220 with the sensor electrodes; and (c) providing electrical stimulation with the stimulator electrodes, which together with the response prevents an onset of incontinence 222. Typically, the methods described herein prevent the onset of urinary incontinence.

The constant electrical stimulation provided at a lower intensity may help individuals with urge incontinence. In some cases, the intensity or duration of the electrical stimulation provided in step (c) may vary according to the response sensed in step (b). In step (c), the response may vary due to stressful events (e.g., coughing, laughing, or exercising) that may require increased electrical stimulation to prevent the onset of incontinence. In some cases, the time period between sensing parameter 224 and providing electrical stimulation 226 may be described as response time 228, such as Figure 6B In some cases, stimulation may be provided for a duration 227 of stimulation.

By developing an iteratively trained machine learning classifier, reaction time can be minimized and improved incontinence prevention can be achieved.
[0136] Figures 12A-12B A workflow of a method 1200 for preventing an episode of incontinence in an individual patient is shown. The method may include the following steps: (a) implanting sensor electrodes and stimulator electrodes into the body of the individual 1202; (b) sensing a parameter associated with a response from the individual, wherein the response is user-induced stimulation 1204; and (c) providing electrical stimulation with the stimulator electrodes to prevent an incontinence event 1206. In some cases, user-induced stimulation may be used to prevent an episode of incontinence. Fig. 12BAs shown, the detected EMG signal 1208 can be analyzed by a classifier 1210 described elsewhere herein to determine when a signal of an EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor signal, or any combination thereof has exceeded a predetermined threshold value described elsewhere herein. Once the classifier 1210 has determined that the signal 1208 does represent an incontinence event, the processor described elsewhere herein can enable stimulation 1212 to prevent the occurrence of the incontinence event. In some cases, the stimulation 1212 can include an extended period of stimulation 1211, which can extend beyond the time that the classifier 1210 determines that an incontinence event exists. In some cases, the extended period of stimulation 1211 can include a duration equal to the duration that the subject continues to purposefully or intentionally produce a muscle contraction.
[0137] In some cases, the extended period of stimulation 1211 may include about 1s to about 30s. In some cases, the extended period of stimulation 1211 may include about 1s to about 3s, about 1s to about 5s, about 1s to about 8s, about 1s to about 10s, about 1s to about 12s, about 1s to about 15s, about 1s to about 18s, about 1s to about 20s, about 1s to about 22s, about 1s to about 24s, about 1s to about 30s, about 3s to about 5s, about 3s to about 8s, about 3s to about 10s, about 3s to about 12s, about 3s to about 15s , about 3s to about 18s, about 3s to about 20s, about 3s to about 22s, about 3s to about 24s, about 3s to about 30s, about 5s to about 8s, about 5s to about 10s, about 5s to about 12s, about 5s to about 15s, about 5s to about 18s, about 5s to about 20s, about 5s to about 22s, about 5s to about 24s, about 5s to about 30s, about 8s to about 10s, about 8s to about 12s, about 8s to about 15s, about 8s to about 18 s, about 8s to about 20s, about 8s to about 22s, about 8s to about 24s, about 8s to about 30s, about 10s to about 12s, about 10s to about 15s, about 10s to about 18s, about 10s to about 20s, about 10s to about 22s, about 10s to about 24s, about 10s to about 30s, about 12s to about 15s, about 12s to about 18s, about 12s to about 20s, about 12s to about 22s, about 12s to about 24s, about In some cases, the extended period 1211 of stimulation may include about 1 s, about 3 s, about 5 s, about 8 s, about 10 s, about 12 s, about 15 s, about 18 s, about 20 s, about 15 s to about 22 s, about 15 s to about 24 s, about 15 s to about 30 s, about 18 s to about 20 s, about 18 s to about 22 s, about 18 s to about 24 s, about 18 s to about 30 s, about 20 s to about 22 s, about 20 s to about 24 s, about 20 s to about 30 s, about 22 s to about 24 s, about 22 s to about 30 s, or about 24 s to about 30 s. In some cases, the extended period 1211 of stimulation may include about 1 s, about 3 s, about 5 s, about 8 s, about 10 s, about 12 s, about 15 s, about 18 s, about 20 s, about 22 s, about 24 s, or about 30 s. In some cases, the extended period of stimulation 1211 may include at least about 1 s, about 3 s, about 5 s, about 8 s, about 10 s, about 12 s, about 15 s, about 18 s, about 20 s, about 22 s, or about 24 s. In some cases, the extended period of stimulation 1211 may include at most about 3 s, about 5 s, about 8 s, about 10 s, about 12 s, about 15 s, about 18 s, about 20 s, about 22 s, about 24 s, or about 30 s.
[0138] In some cases, there may be a delay between the onset of an incontinence event in the raw EMG, ENG, accelerometer, gyroscope, magnetometer, pressure sensor, or any combination thereof signal data and the start of electrical stimulation 1209. Once the classifier is trained 1210 on a sufficiently large and varied data set, such delays can be minimized, thereby further improving the performance of the device in preventing incontinence events. In some cases, sensing can include determining the individual's global positioning system (GPS) location, which is combined with parameters associated with responses from the individual for use in preventing the onset of incontinence.
[0139] Various aspects of the disclosure provided herein may include a data processing method. In some cases, the data processing method may include: (i) receiving a measurement of a parameter previously measured by a sensor electrode, the parameter predicting the onset of incontinence of an individual; (ii) analyzing the parameter; and (iii) synthesizing an electrical stimulation signal for an individual so that when the electrical stimulation signal is provided to the individual by the stimulator electrode, the electrical stimulation signal prevents the onset of incontinence together with the effort from the individual to prevent the onset of incontinence. In some cases, the parameter may be associated with a reaction from the individual to prevent the onset of incontinence. In some cases, the parameter may be associated with the effort of the individual to try to prevent the onset of incontinence, and wherein the electrical stimulation signal is synthesized to supplement the effort of the individual with an electrical stimulation pattern, which together with the effort of the individual will be sufficient to prevent the onset of incontinence. In some cases, the reaction from the individual may not be sufficient to prevent the onset of incontinence by itself, and the electrical stimulation signal is sufficient to prevent the onset of incontinence when applied, plus the reaction.
[0140] In some cases, the onset of incontinence may include urinary incontinence. In some cases, the onset of incontinence may include fecal incontinence. In some cases, the onset of incontinence may include urinary stress incontinence. In some cases, the onset of incontinence is urinary incontinence and is an urge incontinence type.
[0141] In some cases, the parameter may include a signal from a sensor electrode configured to sense a contraction of an individual muscle associated with a partial contraction of a sphincter controlling bladder or bowel discharge. In some cases, the electrical stimulation signal may include electrical stimulation of the pudendal nerve. In some cases, the electrical stimulation signal may be synthesized to include a constant electrical stimulation component and a component specific to the measurement parameter. In some cases, the intensity or duration of the electrical stimulation provided by the electrical stimulation signal may vary according to the value of the received parameter. In some cases, the parameter may include an EMG signal. In some cases, the EMG signal may determine that a contraction of at least one pelvic muscle has occurred. In some cases, the intensity of the EMG signal may be proportional to the intensity of the contraction of at least one pelvic muscle. In some cases, the electrical stimulation signal may include a first signal and a second signal for stimulating a first pudendal nerve and a second pudendal nerve, respectively. In some cases, the method may further include recording a signal previously measured by the sensor electrode. In some cases, the method may further include synthesizing an adjustment signal to adjust the sensor electrode in response to the recorded signal.
[0142] Evaluation of incontinence treatment
[0143] Postoperative ambulatory assessment
[0144] In some embodiments, various dynamic assessments can be performed to determine the effectiveness of the implantation procedure. In some embodiments, the implanted IPG allows the downloading of telemetry data (input, output, and event classification). In some embodiments, the participant can be in a conscious dynamic setting, and a series of resting and stimulating electrophysiological data can be recorded. In some embodiments, at the beginning of treatment (24-48 hours after implantation), sensory and motor responses can be determined from different sensor electrodes on the implanted leads. In some embodiments, based on the response, the electrode with the most adequate response can be selected to start treatment.
[0145] In some embodiments, the patient may experience different physiological events to program the IPG. In some embodiments, these events may include coughing, Valsalva maneuvers, lifting 5kg weights, or any combination thereof. In some embodiments, pelvic floor EMG can be measured using transvaginal and / or anal probes. In some embodiments, urethral pressure can be measured. In some embodiments, a continuous "still" recording of 1 hour can be performed for input and output (downloaded via telemetry).
