[0053] Wireless power transfer, or wireless power delivery, is used to deliver power from a power source to an electronic device without a mechanical connection. Wireless power transfer systems are used in a variety of applications, such as charging batteries in mobile computing devices, such as smartphones or wearable devices. Wireless power transfer systems are also used to deliver power percutaneously or through the skin to medical devices implanted in a patient's body, to directly power the implanted medical device, or to charge the energy storage system of the implanted medical device. Examples of wireless power transfer systems include inductive charging and radio frequency (RF) charging.

[0054] In some examples, percutaneous charging is performed via inductive power transfer or transmission, as illustrated herein. The energy storage system of an implantable medical device can be charged using an external charger configured to provide inductive power transfer. Inductive power transfer can be performed using inductive coupling between conductors, which can be formed as coils of wire, such as a primary conductor in a charger (which may include a primary coil) and a secondary conductor in the implantable medical device (such as, for example, a secondary coil). Power is transferred from the primary conductor to the secondary conductor using a magnetic field. Alternating current through the primary conductor generates an oscillating magnetic field. This magnetic field passes through the secondary conductor and induces an alternating electromotive force (or EMF), such as a voltage, generating alternating current in the secondary conductor. The induced alternating current can directly drive a load in the implantable medical device, or be rectified to direct current by a rectifier in the implantable medical device, which drives the load. Resonant inductive coupling is a type of inductive coupling in which power is transferred between two resonant circuits via magnetic fields, one in the charger and one in the implantable medical device. Each resonant circuit may include a wire coil connected to a capacitor, or a self-resonant coil or other resonator with internal capacitance. The resonant circuits, or tank circuits, are tuned to resonate at approximately the same resonant frequency. Resonance between the conductors can significantly increase the coupling and power transfer between the charger and the implantable medical device. In this example, the external charger is not mechanically connected to the implantable medical device, and the external charger can be used to charge the implantable medical device from a relatively short distance.

[0055] Figure 1An embodiment of a medical system 20 is illustrated. The medical system 20 includes an implantable medical device 30 that can be fully implanted into a patient 22. The implantable medical device 30 includes a housing 32 that forms a first internal compartment 34 within the implantable medical device 30. The implantable medical device 30 includes a head 36 coupled to the housing 32. The head forms a second internal compartment 38 within the implantable medical device 30. The implantable medical device 30 may include an energy storage system, such as a rechargeable power source 42 and electronic components 44 within the first internal compartment 34. An antenna 46 is disposed within the second internal compartment 38 and electrically coupled to the electronic components 44. The antenna 46 is configured to receive wireless communication signals, and in some embodiments, the antenna is also configured to transmit wireless communication signals. A secondary conductor 48 is disposed within the second internal compartment 38 and electrically coupled to the electronic components 44. The secondary conductor 48 is configured to receive wireless power signals. In some embodiments, the wireless power signal is provided to the electronic component 44 to charge the rechargeable power supply 42. In some embodiments, the housing 32 includes a fluid circuit 50 disposed within a third internal compartment 52. The third internal compartment 52 is hermetically isolated from the first internal compartment 34, such as via a hermetically sealed seal or frame. The electronic component is electrically coupled to the fluid circuit 50, such as via a hermetically sealed interface 54, to operate the fluid circuit 50. In some embodiments, the first internal compartment 34 is hermetically isolated from a second internal compartment 38, and the antenna 46 and the secondary conductor 48 are electrically coupled to the electronic component 44 via a hermetically sealed feedthrough connection 56.

[0056] The implantable medical device 30 shown is coupled to a reservoir 60 filled with fluid 62 (such as a sterile saline solution), which is in fluid communication with a fluidic circuit 50. The implantable medical device 30 is coupled to an inflatable member 64 in fluid communication with both the fluidic circuit 50 and the reservoir 60 to contain the fluid 62. Electronic components 44 provide monitoring and control for various operations of the fluidic circuit 50. The fluidic circuit 50 can provide for the transfer of fluid 62 between the reservoir 60 and the inflatable member 62. In some embodiments, electronic components 44 may include a charging system, a communication system, and a control system. In some embodiments, the fluidic circuit 50 may include a manifold and fluidic components such as a pump assembly, a valve assembly, and a pressure sensor.

[0057] The implantable medical system 20 also includes a charger 70, also referred to as a wireless charger, located outside the patient 22 or across the percutaneous boundary 24 (such as near the surface of the patient's skin close to the implantable medical device 30) to provide a power signal to the medical device 30 and, in some examples, to provide telemetry. In some embodiments, percutaneous charging is performed via radio frequency power transfer or transmission or inductive power transfer or transmission. The charger 70 is not mechanically connected to the implantable medical device 30, and the charger 70 can be used to charge the implantable medical device 30 from a relatively short distance. For example, the charger 70 is placed against the patient 22 and close to the implantable medical device 30 to inductively transfer energy and replenish the rechargeable power supply 42.

[0058] In embodiments of charger 70, inductive power transfer can be performed using inductive coupling between conductors, which can be formed as wire coils, such as a primary coil in charger 70 and a secondary conductor 48 in implantable medical device 30. Power is transferred from charger 70 to secondary conductor 48 using a magnetic field. Alternating current through the primary coil generates an oscillating magnetic field. This magnetic field passes through secondary conductor 48 and induces an alternating electromotive force (or EMF), such as a voltage, generating alternating current in secondary conductor 48. The induced alternating current can directly drive a load in implantable medical device 30, or be rectified into direct current by a rectifier in implantable medical device 30 (such as part of electronic component 44), which drives the load. In some embodiments, the induced current is applied to supplement rechargeable power supply 42 via electronic circuitry 44, and in some embodiments, the induced current is used to drive fluid circuitry 50 via electronic component 44. Resonant inductive coupling is a type of inductive coupling in which power is transferred between two resonant circuits, one in charger 70 and one in implantable medical device 30, via a magnetic field. Each resonant circuit may include a wire coil connected to a capacitor, or a self-resonant coil or other resonator with internal capacitance. The resonant circuits or energy storage circuits are tuned to resonate at approximately the same resonant frequency. Resonance between the conductors can significantly increase the coupling and power transfer between the charger 70 and the implantable medical device 30.

[0059] In the example, charger 70 delivers magnetic energy to the corresponding implantable device 30 at a preselected frequency using a resonant inductor-capacitor (LC) energy storage circuit to generate an H-field. This energy storage circuit includes a charging coil connected in series with a charging capacitor. Various configurations of charger 70 can share a common coil design, and the preselected charging frequency is determined by the selected energy storage capacitance of the charging capacitor. The energy storage circuit can oscillate at the resonant frequency. The phase-locked loop in the energy storage circuit is generated by pulsed the applied energy storage voltage in phase with the energy storage current. During resonance, the energy storage current approximately or substantially sinusoidal over time. The energy storage circuit achieves maximum energy storage power when the energy storage voltage pulse is time-aligned with the energy storage current. The charging power can be adjusted by changing the amplitude and duty cycle of the energy storage voltage pulse input to the energy storage circuit.

[0060] The charger 70 is available in different configurations depending on the charging frequency and communication scheme used in conjunction with the implantable medical device 30. For example, a first configuration of the charger 70 may support a two-way inductive telemetry communication scheme and a first charging frequency; a second configuration of the charger 70 may support both radio frequency telemetry and downlink inductive telemetry communication schemes and a second charging frequency; and a third configuration of the charger may support a two-way inductive telemetry communication scheme and a third charging frequency. Inductive charging is presented in this disclosure for illustrative purposes, and the charger 70 may also use other forms of wireless charging to supplement the rechargeable power supply.

[0061] System 20 may also include a handheld programmer 80 configured to wirelessly dock and communicate with the implantable medical device 30 or the charger 70, the handheld programmer also being located outside or external to the patient 22. In one example, the handheld programmer 80 may be implemented as a general-purpose computing device or mobile computing device hosting software applications. For example, the handheld programmer 80 may include a set of controls for percutaneous communication with or operation of the implantable medical device 30 via a communication system, or for communication with or operation of the charger 70. The medical device 30 includes an antenna 46 for receiving and transmitting communication signals with the handheld programmer 80. For example, the handheld programmer 80 and the medical device 30 may communicate via radio frequency signals in the 2.400–2.4835 GHz range, such as in Bluetooth Low Energy communication in a wireless personal network. Alternatively or alternatively, the handheld programmer 80 or the charger 70 may employ other forms of wireless communication, which may include other forms of radio frequency communication or inductive communication. The handheld programmer 80 can be configured with a user interface (such as a graphical user interface) to wirelessly operate the medical device 30, such as receiving commands via soft buttons, receiving feedback or parameters from the medical device 30, updating the control system on the medical device, and interfacing with a computer network to provide telemetry or allow control of the medical device 30 by a system connected to a remote computer network. For example, a user can use the handheld programmer 80 to actuate the medical device 30 such that fluid 62 is pumped from the reservoir 60 into the inflatable member 64, or fluid 62 is released from the inflatable member 64 back to the reservoir 60.

[0062] The system disclosed herein may optionally include additional components. System 20 may include a charging dock that can be plugged into a wall outlet and configured to charge the internal battery of charger 70. Charger 70 may also be used in conjunction with a fixation product of system 20 to hold charger 70 in proximity to implantable medical device 30 during a charging session. The fixation product may include a fixation strap worn around a portion of patient 22, such as a waist belt for implantable medical device 30 located in the abdomen, back, hip, or flank of patient 22, or a fixation shawl worn around the neck with counterweights to balance charger 70 for implantable medical device 30 located in the chest region of patient 22. The fixation product receives charger 70 to hold charger 70 in place relative to the fixation product such that, in one example, charger 70 does not rotate during a charging session and generally does not move relative to implantable medical device 30, and secures charger 70 to prevent it from falling off unless intentionally removed from the fixation product.

[0063] The implantable medical device 30 can be subcutaneously implanted in an implantation site or pocket within the patient 22. In some examples, another component of the implantable medical device 30 may occupy the same or additional location within the patient 22. The implantable medical device 30 can be configured to deliver therapy to the patient, monitor parameters within the patient's body, and receive and deliver signals to the patient, such as at regular intervals, continuously, or in response to detected events (such as events detected by sensors, events received from another implantable device (not shown), or events received from components of the implantable medical system 20, such as charger 70 or handheld programmer 80). The implantable medical device 30 can be configured to detect various physiological signals that can be used in conjunction with various diagnostic, therapeutic, and other monitoring implementations. The implantable medical device 30 can be used in urology, neurology, cardiology, and other applicable fields where implantable medical devices with power systems or for receiving and transmitting signals are used.

[0064] In some embodiments, the implantable medical device 32 is configured as a urological therapy device to deliver selective stimulation, for example, to the sacral nerve, for the treatment of urological disorders such as bladder control or erectile dysfunction. In other examples, the implantable medical device is configured as a gastrointestinal device to treat, for example, gastroesophageal reflux disease (GERD). In other examples, the implantable medical device 32 may be configured as a neurostimulation therapy device for pain management, etc. In still other examples, the implantable medical device 32 may be a cardiac rhythm management device for sensing and stimulating cardiac tissue to treat cardiac arrhythmias (e.g., bradycardia, tachycardia) and for cardiac resynchronization therapy. In still other embodiments, the implantable medical device 32 may be configured as a monitoring-only device without therapeutic function to monitor a patient's physiological parameters. In summary, this disclosure is not limited to any clinical application and is not limited to any implantable device that requires electricity to operate as intended.

[0065] Figure 2 An example implantable medical device 200 is shown, such as an implantable urinary device connected to an inflatable penile prosthesis, which may correspond to implantable medical device 30. In the example, implantable medical device 200 includes, within a closed system, inflatable components (such as a pair of inflatable cylinders 202); a reservoir 204 that can be filled with fluid (such as a sterile saline solution 206); and an electromechanical actuator 208. The reservoir 204 is fluidly coupled to the actuator 208 via conduit 210, and the actuator 208 is fluidly coupled to the cylinders 202 via conduit 212. For example, conduits 210, 212 may be kink-resistant conduits made of silicone elastomer.

[0066] Actuation device 208 includes a hermetically sealed housing 220 formed of a biocompatible material, such as titanium or steel. In one example, housing 220 is formed via multiple walls welded together. Actuation device 208 includes an internal fluid loop to fluidly couple reservoir 204 to column 202 via conduits 210, 212. Internal electronics powered by a rechargeable power source can provide monitoring and control for various operations of the fluid loop, such as the transfer of fluid 206 between reservoir 204 and column 202. In one example, electromechanical actuation device 208 can be coupled with… Figure 1 Corresponding to the implantable medical device 30, the reservoir 204 and the fluid 206 can be respectively connected to Figure 1 The reservoir 60 and the fluid 62 correspond to each other, and the column 202 can be with Figure 1 The inflatable component 64 corresponds to this.

[0067] In one embodiment, housing 220 is configured to house a rechargeable energy storage system, electronic components, and a fluidic circuit. In some embodiments, the housing includes multiple compartments that can be separated by a frame and are hermetically sealed to each other. The electronic components can be implemented using various components, including resistors, capacitors, transistors, and integrated circuits disposed on one or more printed circuit boards in a first internal compartment. The fluidic circuit can be implemented via a titanium manifold in another internal compartment and an electromagnetic or piezoelectric pump. In one example, housing 220 may include attachment devices, such as loops 222, 224 formed on the walls to receive sutures that can be applied to anchor the actuator 208 to the patient's body.

[0068] The actuation device 208 includes a head 226 to form a second internal compartment, which includes power interface and communication interface structures, such as a secondary conductor 228 and an antenna 230. The head 226 is configured to allow the transmission of power signals and communication signals between the secondary conductor 228 and the charger 70, and between the antenna 230 and the handheld programmer 80 or the charger 70. The secondary conductor 228 and the antenna 230 are electrically coupled to electronic components within a first compartment. In embodiments where the first and second internal compartments are hermetically sealed, the secondary conductor 228 and the antenna 230 are coupled to the electronic components via a hermetically sealed feedthrough connection.

[0069] The column 202 is typically implanted in the corpora cavernosa of the penis, and the reservoir 204 is usually implanted in the retropubic space or Retzius space, or between the transversus abdominis and rectus abdominis muscles. An electromechanical actuator 208 can be implanted in the abdomen at a location determined by a clinician. A sterile saline solution 206 can be pumped from the reservoir 204 into the chamber of the column 202 via tubing 210, 212 under the action of the actuator 208. For example, the actuator 208 may include an electromechanical pump and valve within a fluidic circuit. The column 202 replaces dysfunctional or limited erectile tissue in the penis, and an erection is achieved by filling the column 202 with the saline solution 206. After intercourse, the actuator 208 releases the saline solution 206 from the column 202, and the fluid returns to the reservoir 204 via tubing and a fluidic circuit within the actuator 208.

[0070] In another example of an implantable medical device incorporating features of an electromechanical actuator (which incorporates features of medical device 30), an inflatable member 64 may correspond to an inflatable cuff, which may be implemented as an artificial urethral sphincter. In some embodiments, the inflatable cuff is positioned around the urethra near the bladder. The actuator is applied to pump fluid from a reservoir, causing the cuff to inflate and close the urethra. The cuff is then deflated to allow the patient to empty the bladder. This disclosure describes features of medical device 30 with reference to penile prostheses (such as medical device 200) for illustrative purposes, and the features of medical device 30 may be applied to other embodiments and components.

[0071] Figure 3 It shows Figure 2 An exploded view of the example actuation device 208, wherein like parts are labeled with the same reference numerals. The housing 220 includes a first sidewall 232, a second opposing sidewall 234, a peripheral wall 236, and a frame 240. In the example actuation device 208, the first sidewall 232, the second sidewall 234, and the peripheral wall 236 are hermetically sealed together. The frame 240 is disposed within the housing 220 to form a first internal compartment 252 and a third internal compartment 254, such that the first internal compartment 252 and the third internal compartment 254 are hermetically sealed together. In the example, the frame 240 may be integrally formed with the peripheral wall 236 or the first sidewall 232 or the second sidewall 234. In another example, the frame 240 is welded to the peripheral wall 236 or to the first sidewall 232 or the second sidewall 234. In the example shown, the first sidewall 232, the peripheral wall 236, and the frame 240 form the first internal compartment 252. The second side wall 234, the peripheral wall 236, and the frame 240 form the internal compartment 254.

[0072] The actuation device 208 may include a head 226 attached to a housing 220 to form a second internal compartment 258 between an inner surface of the head 226 and an outer surface of the housing 220. This second internal compartment 258 includes power and communication interface structures, such as a secondary conductor 228 and an antenna 230. In one embodiment, the second internal compartment 258 is located outside a first internal compartment 252 of the hermetically sealed housing 220. The head 226 is configured with a dielectric or insulating material (such as a radome) to allow the transmission of power and communication signals between the antenna 230 and a handheld programmer or charger, and between the secondary coil 228 and the charger. For example, the head 226 may be composed of an overmolded polymer fixed to the housing 220 and includes the secondary coil 228 and the antenna within an internal region 258. In this example, the secondary conductor 228 and the antenna 230 are made of a biocompatible material.

[0073] The actuation device 208 includes an energy storage system (such as a rechargeable power supply 260 or a rechargeable battery) and electronic components 262 within a first internal compartment 252. Electronic components 262 may be disposed on a circuit board 264 (such as multiple circuit boards) within the first internal compartment 252. The rechargeable battery 260 may take various forms suitable for providing power for generating a desired electrical signal and storing the power supplied from the electronic components 262. For example, the battery 260 may incorporate lithium-ion (Li+) chemistry, i.e., a lithium-ion battery, to operate the electronic components 262. In one example, the electronic components 262 may be implemented by various components, including resistors, capacitors, transistors, and integrated circuits disposed on the circuit board 264. Secondary coil 228 and antenna 230 are electrically coupled to the electronic components 262 within the first compartment 252, such as via a hermetically sealed feedthrough connection.

[0074] Electronic component 262 may include a charging system, a communication system, and a controller. The charging system includes hardware configured to interface with secondary coil 228 to receive and provide power signals in a manner suitable for charging battery 260, and may include circuitry to reduce the possibility of overcharging battery 260. The communication system includes hardware configured to interface with antenna 230 to receive electrical communication signals. For example, the communication system may be configured to communicate via wireless personal area network (PAN) technologies such as Bluetooth Low Energy, which are compatible with multiple operating systems that can be applied to a mobile device configured as a handheld programmer. The communication system may include integrated circuits to implement applied communication technologies. In some examples, the communication system may be used to transmit communication signals to other devices, such as chargers or handheld programmers, and the communication system may be implemented to generate and provide communication signals to antenna 230 for transmission. In some examples, the communication system may be configured to receive and transmit radio frequency signals via antenna 230. The controller may include a microcontroller for operating the charging system and for receiving and responding to communication signals, or for generating communication signals from the communication system.

[0075] The actuation device 208 also includes a fluidic circuit 270 located within a third internal compartment 254 and within a frame 240, opposite the battery 260 and the electronic component 262. In an example, the frame 240 may include an opening 242 including a hermetically sealed interface 244, such as a feedthrough hermetically secured to the frame. The electronic component 262 is operatively coupled to the fluidic circuit 270 across the frame 240 via the hermetically sealed interface 244. For example, a controller of the electronic component 262, powered by the battery 260, may cause operation of the fluidic circuit 270, such as controlling and monitoring the fluidic circuit 270. The fluidic circuit 270 includes a manifold 272 and a fluidic component 274 operatively coupled to the manifold 272. In the example shown, the manifold 272 is a structure integrated into the frame 240 such that the manifold 272 and the frame 240 together form a hermetically sealed barrier between the first internal compartment 252 and the second internal compartment 254. For example, battery 260, circuit board 264 or electronic component 262 may be coupled to a first main surface of manifold 272 in first internal compartment 252, and fluid component 274 may be operatively coupled to a second and opposite main surface of manifold 272 in second internal compartment 254.

[0076] A fluidic circuit 270 provides for the transfer of fluid 206 between a reservoir 204 and an inflatable member, such as a column 202. A manifold 272 (which may be an airtight manifold) divides and contains fluid from a first internal compartment 252 to reduce the chance of fluid exchange and directs fluid from a first port 276 to a second port 278 via an internal fluid passage or channel. In the example shown, a fluidic component 274 includes multiple fluid pumps (such as pumps 280, 282) and a valve 284 mounted in the manifold 272, fluidly communicating with the manifold passage to transfer fluid from the first port 276 to the second port 278. In an exemplary fluidic architecture, the pumps and valves are fluidly communicating with a single fluid passage between ports 276, 278. The fluidic component 274 also includes a pressure sensor 286 operatively coupled to and fluidly communicating with the manifold 272 to detect the pressure of the fluid within the manifold 272. As indicated, the fluid component 274 is included in a planar configuration on the manifold 272, wherein pumps 280, 282, valve 284, and pressure sensor 286 are mounted in the manifold 272 on a single plane to achieve a slim profile within the second internal compartment 254. The manifold 272 may include chambers 288 formed into the second main surface, wherein these chambers are fluidly coupled to a single channel within the manifold 272. These chambers are configured to accommodate pumps 280, 282, valve 284, and pressure sensor 286. The manifold 272 may accommodate a piezoelectric pump. The manifold 272 may accommodate a cap 290 above the fluid component 274, which can be hermetically sealed to the second main surface.

[0077] Example actuator 208 may include an anti-kink conduit 292 that may extend through head 226 and be attached to ports 276, 278 via components such as barbs 294 and O-rings. Anti-kink conduit 292 may be attached to conduits 210, 212 to fluidly couple actuator 208 to reservoir 204 and inflatable member (such as column 202).

Actuator 408a includes a head 426 to form a second internal compartment 438, which includes power and communication interface structures, such as secondary conductor 428a and antenna 430a.

[0080] The head 426 is configured to allow the transmission of electrical and communication signals between the antenna 430a and a handheld programmer or charger, and between the secondary conductor 428a and the charger.
