Sensor Implant Device Anchoring for Left Atrial Pressure Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring cardiac pressure, particularly in the left atrium, are inadequate for early detection of congestive heart failure, as they often rely on invasive procedures or indirect measurements that are unreliable and may not accurately predict fluid buildup or heart failure symptoms until symptoms become severe.
Innovation Solution
The development of sensor implant devices with integrated pressure sensors that can be implanted in the heart to directly monitor left atrial pressure, providing real-time data for early detection of heart failure and guiding medication administration to prevent hospitalization and morbidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive procedures or indirect measurements are used to monitor cardiac pressure, then the monitoring can be performed with existing technology, but the measurement precision and reliability are inadequate for early detection of heart failure
Solution Approach 1:
The patent combines the sensor device with a delivery catheter into an integrated system. The sensor is delivered through the catheter to the target location in the heart, eliminating the need for separate implantation procedures and reducing overall system complexity while maintaining high measurement precision through direct contact sensing
Solution Approach 2:
The delivery catheter serves as an intermediary tool that facilitates the minimally invasive insertion of the sensor device into the heart. This mediator enables precise positioning of the sensor at the target location (left atrium or ventricle) while keeping the procedure less invasive than direct surgical implantation
2Reliability
If direct left atrial pressure monitoring is implemented, then early detection of heart failure is enabled, but the device complexity and implantation procedure become more complex
Solution Approach 1:
The sensor device is designed to monitor pressure in multiple cardiac chambers (left atrium and left ventricle) and can detect multiple physiological parameters. This multi-functionality increases reliability for comprehensive heart failure detection while avoiding the need for multiple separate devices, thereby not proportionally increasing device complexity
Solution Approach 2:
The sensor device is nested within the delivery catheter during the implantation procedure. This nesting allows the sensor to be transported through the vasculature to the target location and then deployed, simplifying the implantation process despite the sophisticated functionality of the sensor itself
3Productivity
If sensor implant devices are used for real-time monitoring, then proactive intervention is enabled, but the ease of operation and implantation procedure are reduced
Solution Approach 1:
The sensor device is pre-loaded into the delivery catheter in a compressed or collapsed state before the procedure. This preliminary preparation allows for smooth navigation through the vasculature and simplifies the implantation process, as the sensor is already positioned and ready for deployment at the target location
Solution Approach 2:
The sensor device transitions from a compressed state during delivery to an expanded functional state after implantation. This dynamic transformation allows the device to navigate through narrow vasculature in a compact form and then expand to its full functional configuration at the implantation site, facilitating easier implantation while maintaining high monitoring efficiency

AI summary
A sensor implant device comprises a sensor body, at least a first sensor component, and one or more anchoring features coupled to the sensor device and configured to anchor within a tissue wall. The one or more anchoring features are configured to assume an unexpanded form during delivery and configured to expand into the tissue wall.
