Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to an early warning system, method and device based on left atrial appendage pressure monitoring. Background Technology

[0002] Heart failure (HF) is a severe manifestation or late stage of various heart diseases, with high mortality and readmission rates. When HF occurs, the heart's pumping ability is significantly weakened, and the earliest indicator of this change is an increase in intra-atrial fluid pressure—atrial pressure changes. Early warning of HF can be achieved through non-invasive measurements such as vital signs, oxygenation index, and thoracic conductivity. These methods are mainly divided into non-invasive monitoring and atrial pressure monitoring. Currently, non-invasive measurement devices primarily rely on algorithm design, which has limited sensitivity and specificity in diagnosing HF and results in relatively large pressure errors. Most devices use the second method, measuring atrial pressure for precise monitoring. Traditional left atrial pressure measurement requires creating an incision and inserting a catheter into the atrium to obtain pressure values. While this method is accurate and sensitive, it is not suitable for long-term monitoring and early warning applications in HF patients.

[0003] Existing patents disclose wired implantable pressure sensors. For example, publication number CN113677277A discloses a device for implantation in the left atrial appendage of the heart, which can effectively monitor atrial pressure. However, its wired and power supply design is not suitable for long-term monitoring and early warning applications, limiting its widespread use. Cordella and CardioMEMS are pressure sensors implanted in the pulmonary artery, which can effectively monitor pulmonary artery pressure and provide early warning of heart failure. However, they measure pulmonary artery pressure and cannot directly measure atrial pressure, and there is a risk of pulmonary embolism at the implantation site. Patent publication number US11026590B2 provides a pressure sensor placed in the atrial septum, which can monitor the pressure level of the left atrium in real time and provide early warning of heart failure. However, its placement in the atrial septum makes it impossible for patients to undergo interventional procedures into the left atrium again in the future, limiting the treatment of various left ventricular diseases.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Reference Figure 1The present invention provides an embodiment of an early warning system based on left atrial appendage pressure monitoring, comprising: a first module; placed inside the target area to monitor the pressure data signal of the target area; the first module sends the pressure data signal to a second module for external monitoring and data management, and generates a pressure waveform data signal; the second module sends the pressure waveform data signal to a cloud module for data synchronization.

[0044] In this embodiment, the target area is the left atrial appendage. The first module monitors the pressure in the target area, generates a pressure data signal, and sends it to the second module. The first and second modules transmit data wirelessly. After receiving the pressure data signal externally, the second module generates a pressure waveform data signal, which is then displayed on a display unit. This allows for real-time monitoring of the pressure inside the atrium and data interconnection and early warning monitoring via a cloud platform. This enables real-time measurement of the patient's atrial pressure, data recording and uploading, threshold interpretation, and timely early warning of heart failure, thus achieving remote closed-loop management of heart failure.

[0045] The first module includes a monitoring unit that monitors the pressure in the target area and generates pressure data signals; the first module also includes an external measurement unit that monitors and obtains pressure reference signals; the pressure data signals and pressure reference signals are transmitted through the first transmission unit.

[0046] In this embodiment, the pressure signal is calibrated by an external measurement unit to obtain a pressure reference signal. After calibration, the pressure in the target area is monitored by a monitoring unit to obtain a pressure data signal. The pressure reference signal and the pressure data signal are sent to the second module by a first transmission unit. Auxiliary calibration is performed based on the pressure reference signal, and deviation calculation is performed on the pressure data signal to improve the accuracy of monitoring.

[0047] The second module includes a second transmission unit, which receives the pressure data signal sent by the first module and then processes the data through the processing unit; it also includes a calibration unit, which receives the pressure reference signal sent by the external measurement unit for calibration, generates a pressure waveform data signal, and sends it to the storage unit and the display unit for output storage and display.

[0048] In this embodiment, the second module receives the pressure data signal sent by the first transmission unit through the second transmission unit, receives the pressure reference signal through the calibration unit, amplifies the pressure data signal through an amplifier, filters redundant signals through a filtering circuit to remove interference from extraneous signals, and performs analog-to-digital conversion through an A / D module to convert the received pressure data signal into a corresponding digital signal, which is then temporarily stored in the storage unit. The data is displayed through the display unit for easy reading of pressure monitoring data. After the storage unit temporarily stores the data, it sends the data to the cloud server for cloud storage, which not only backs up the data but also allows external devices to view the monitored data.

[0049] The second transmission unit sends an activation signal to the first transmission unit, controlling the monitoring unit to start pressure detection.

[0050] In this embodiment, the first module is in a dormant state when no pressure monitoring is being performed. An activation signal is sent to the first transmission unit through the second transmission unit to control the first module to switch from the dormant state to the working state and to monitor and collect pressure at the left atrial appendage.

[0051] The first transmission unit and the second transmission unit transmit data through an LC resonant circuit.

[0052] In this embodiment, the first transmission unit and the second transmission unit are coils. Through an LC resonant circuit, the coils on both sides are mutually inductively coupled to achieve signal coupling and transmission.

[0053] Reference Figure 2 The present invention also provides an embodiment of an early warning method based on left atrial appendage pressure monitoring, the method being applicable to any of the systems described above, comprising:

[0054] S1: The pressure reference signal is calibrated for the monitoring component. After the monitoring component is delivered to the target area, it is monitored and pressure data signals are generated.

[0055] S2: Set a pressure threshold through the external monitoring device, receive pressure data signals, compare them with the pressure threshold, if the pressure data signal is lower than the pressure threshold, it is judged as normal and saved to the cloud; if the pressure data signal is higher than the pressure threshold, it is judged as high pressure, the external monitoring device will issue a warning through the display screen, and after saving the pressure data to the cloud, it will provide a real-time warning.

[0056] S3: When the pressure data signal drops to the pressure threshold, the external monitoring device recalibrates the monitoring components and returns to step S1.

[0057] In this embodiment, after the monitoring component is delivered to the target area, it needs to be calibrated according to the current pressure situation of the target area. After calibration, the pressure threshold of the external monitoring device is set, and the corresponding pressure data signal is generated by the monitoring component and sent to the external monitoring device. The external monitoring device compares the pressure data signal with the set pressure threshold to determine the magnitude between the pressure data signal and the pressure threshold. If the pressure data signal is less than the pressure threshold, it is determined that the pressure is normal, and the measured pressure data is sent to the cloud for storage. If the pressure data signal is greater than the pressure threshold, an early warning reminder can be issued through the display unit. Specifically, the display unit issues an early warning reminder by setting a color change or flashing, and sends the pressure data to the cloud for storage. After the measured pressure data is sent to the cloud, it can be queried through software or a mini-program, and reminders can be sent by phone or text message to facilitate timely intervention and treatment.

[0058] Reference Figures 3-9 The present invention also provides an embodiment of a pressure monitoring device, which is applicable to any of the systems and methods described above, comprising:

[0059] The monitoring component 3 is connected to the conveying steel cable 2 by a thread and is conveyed along the setting direction of the conveying conduit 1 along the conveying steel cable 2;

[0060] The inside of the delivery conduit 1 is equipped with a working channel, and the delivery steel cable 2 passes through the delivery conduit 1 to deliver the monitoring components to the target area;

[0061] An anchoring component 4 is provided on the outside of the monitoring component 3. The anchoring component 4 is in the first state inside the delivery conduit 1. Under the push of the delivery steel cable 2, it is delivered out of the delivery conduit 1 and changes from the first state to the second state, so that the monitoring component 3 is fixed in the target area. The delivery steel cable 2 is removed so that the monitoring component 3 can monitor the pressure of the target area and send it to the external monitoring device 5.

[0062] In this embodiment, wireless signal transmission is achieved through an LC resonant circuit and an external monitoring device 5. One side of the monitoring component 3 has an external thread, and one side of the delivery cable 2 has a matching internal thread. The monitoring component 3 is connected to the delivery cable 2 via the threaded connection. During delivery, the monitoring component is transported to the target area through the delivery conduit 1. It should be noted that during delivery, the pressure in the target area is first monitored through the delivery conduit 1 to obtain a pressure reference signal, which facilitates subsequent calibration of the monitoring component 3. After monitoring is completed, the monitoring component 3 is transported along the delivery conduit 1... The device is transported in the specified direction. At this time, the monitoring component 3 is in the first state and deforms under force, located inside the delivery conduit 1. The anchoring component 4 is pressed and adhered to the outside of the monitoring component 3. When the output end of the delivery conduit 1 is located in the target area, the delivery cable 2 is pushed to release it, causing the monitoring component 3 to change from the first state to the second state. In the second state, the monitoring component 3 leaves the working channel of the delivery conduit 1. At this time, the anchoring component 4 extends in the radial direction and returns to its natural state. The anchoring component 4 anchors and limits the inner wall of the left atrial appendage, so that the monitoring component 3 adheres to the inner wall of the left atrial appendage.

[0063] The external monitoring device 5 is an active device that integrates a coil coupled to the implanted monitoring component, as well as a control chip for signal reception, amplification, filtering, data storage, and network transmission. Pressure signal monitoring utilizes the LC inductive coupling principle to achieve near-field wireless transmission of pressure. The external monitoring device 5 has a switch and display screen on its exterior, capable of displaying pressure readings. An internal early warning system continuously monitors the pressure; if an abnormally high pressure is detected, the external monitoring device 5 will trigger an alarm. All recorded pressure data signals are transmitted via the network from the external monitoring device 5 to a cloud server, which then shares the data with doctors and patients. Doctors can simultaneously interpret the pressure level and provide timely medical advice to patients.

[0064] The monitoring component 3 includes a housing 31, at least one end face of which is in communication with the outside. A pressure sensor 32 is provided on one side of the housing 31 to monitor pressure signals through the housing 31.

[0065] In this embodiment, the housing 31 is made of a biocompatible material, and a pressure sensor 32 is provided on one side. The surface of the pressure sensor 32 that contacts the blood is the bottom or side, or it can be the side of the housing 31, but the position cannot be higher than 1 / 3 of the overall height of the housing 31. By communicating with the outside, the pressure in the atrium is monitored.

[0066] The anchoring component 4 includes a first anchoring part 41 and a second anchoring part 42. In the second state, the area of ​​the first anchoring part 41 is smaller than that of the second anchoring part 42, which is adapted to the shape of the target area. The first anchoring part 41 extends along the axial direction of the monitoring component 3 to form a plurality of third anchoring parts 43.

[0067] In this embodiment, the first anchoring part 41 and the second anchoring part 42 are occlusion discs made of shape memory alloys such as nickel-titanium alloy. After being delivered to the left atrial appendage via the delivery catheter 1, they automatically deploy. The bottom of the occlusion disc is covered with a flow-blocking membrane to prevent blood from entering the left atrial appendage. The flow-blocking membrane is a biocompatible polymer material that can block large atrial appendages and prevent thrombosis after implantation. The area of ​​the first anchoring part 41 is smaller than that of the second anchoring part 42. Since the left atrial appendage is funnel-shaped with a larger outer diameter than the inner diameter, the first anchoring part 41 extends into the inner side of the left atrial appendage to ensure the occlusion effect. The second anchoring part 42 is located on the outer side of the left atrial appendage for better occlusion and fixation. A third anchoring part 43 is provided on the outer side of the first anchoring part 41. The third anchoring part 43 is made of shape memory alloys such as nickel-titanium alloy. After being delivered to the left atrial appendage via the delivery catheter 1, it automatically deploys and anchors to the pectinate muscle of the left atrial appendage, fixing the entire device.

[0068] A handle 11 is provided on one side of the delivery conduit 1, a liquid channel 12 is provided on one side of the handle 11, and a developing belt 13 is provided on the side away from the handle 11.

[0069] In this embodiment, the delivery conduit 1 is a single-bend delivery conduit, and the developing belt 13 is a fluoroscopic developing belt coated with a fluoroscopic developing coating for development under fluoroscopic light. A pre-reserved channel within the handle 11 allows for the release of the delivery cable 2, and a liquid channel 12 is connected to the same side as the curvature of the delivery conduit 1, allowing the injection of medication to the front end of the delivery conduit 1 via the liquid channel 12.

[0070] In a specific embodiment:

[0071] First, an atrial septal pathway is established via femoral vein puncture. After puncturing into the left atrium, the structure, size, and morphology of the left atrial appendage are displayed by angiography. Angiographic fluid is injected through the fluid channel 12 at the handle 11. Based on the morphology, the distance between the first anchoring part 41 and the second anchoring part 42 on the monitoring component 3 is pre-adjusted in vitro to adjust the depth of insertion into the inner side of the left atrial appendage. Different depth positions can adapt to different depths of the left atrial appendage structure. After being inserted into the left atrial appendage, the pressure and waveform at the left atrial appendage can be directly measured by an external detection device connected to the delivery catheter 1 (existing technology, not described in detail), and a pressure reference signal is obtained. The monitoring component 3 is connected to the delivery cable 2 through the delivery catheter 1 and pushed to the left atrial appendage. The third anchoring part 43 is attached to the pectinate muscle deep in the left atrial appendage. The delivery cable 2 is rotated to fix the monitoring device 3 deep in the left atrial appendage. Then, the delivery catheter 1 is slowly withdrawn to allow the first anchoring part 41 and the second anchoring part 42 to fully unfold and complete the fixation. The first anchoring part 41 and the second anchoring part 42 are observed to see if they are fully unfolded by angiography or ultrasound equipment, thus completing the adjustment of the anchoring component 4.

[0072] After fixation, the liquid channel 12 on the handle 11 is brought into contact with the atrial blood. The atrial fluid pressure will reach the pressure sensor 32 through the connection of the housing 1, generating a pressure data signal. This signal is coupled to an external signal receiver via an LC resonant circuit. The signal monitoring strength of the sensor can be tested before release. An activation signal is sent through the external monitoring device 5 to control the pressure sensor 32 to start pressure monitoring, test the signal strength, and compare it with the pressure reference signal to ensure monitoring accuracy, thus completing the adjustment of the monitoring components.

[0073] The delivery catheter 1 is slowly withdrawn, and the monitoring component 3 is released. The pressure and waveform of the left atrial appendage are monitored again through the delivery catheter 1 to obtain the pressure reference signal after completion. The pressure is monitored again through the external monitoring device 5 to obtain the pressure reference signal, and the implantation is completed.

[0074] After implantation, a pressure threshold is set through external monitoring device 5, and the pressure data signals sent by the monitoring component are compared to realize heart failure early warning. The warning is also sent to external communication devices via the cloud. Specifically, the data information can be sent to the doctor so that medication can be adjusted in time or the pressure threshold can be adjusted according to the patient's condition.

[0075] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
