Sensor Implant Anchoring for Cardiac Pressure Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical technologies face challenges in accurately monitoring cardiac pressure, particularly in the left atrium, which is crucial for early detection and prevention of congestive heart failure, as existing methods are invasive, unreliable, or provide delayed signals for potential heart complications.
Innovation Solution
The development of sensor implant devices with integrated pressure sensors that can be anchored within the heart using various anchoring features such as stent-like, clip, coil, or hook structures, allowing for direct and continuous monitoring of left atrial pressure, enabling proactive intervention in heart failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor implant devices are anchored within the heart using stent-like, clip, coil, or hook structures, then measurement precision of cardiac pressure is improved, but device complexity increases
Solution Approach 1:
The patent combines the sensor device with multiple types of anchoring features (stent-like structures, clips, coils, hooks) into a single integrated implantable device. This merging allows the device to provide both accurate pressure measurement and secure anchoring within the heart, resolving the contradiction between measurement precision and device complexity by unifying these functions in one device.
Solution Approach 2:
The sensor implant device is designed with multi-functionality, serving both as a pressure sensor and as an anchoring device through its integrated stent-like, clip, coil, or hook structures. This universal design allows a single device to perform multiple functions (measurement and anchoring), thereby improving measurement precision without proportionally increasing overall device complexity.
2Reliability
If sensor implant devices are anchored within the heart, then reliability of cardiac pressure monitoring is improved, but ease of operation during implantation deteriorates
Solution Approach 1:
The anchoring features of the sensor device are designed to be dynamic, allowing the device to be delivered in a compressed or collapsed state through catheters and then expanded or deployed at the target site within the heart. This dynamic design enables easier implantation (improving ease of operation) while ensuring reliable anchoring and continuous monitoring (improving reliability) once deployed.
Solution Approach 2:
The sensor device with its anchoring features is designed to be nested within a delivery catheter system during implantation. The device can be compressed or folded within the catheter for easy delivery, then expanded at the target site to provide reliable anchoring. This nesting approach simplifies the implantation procedure while ensuring reliable long-term monitoring.
3Loss of time
If sensor implant devices are used for direct monitoring, then loss of time for detecting heart failure symptoms is reduced, but object-generated harmful factors (risk of implantation) increase
Solution Approach 1:
The sensor implant device is designed to be self-contained and self-sustaining, with integrated sensors, power sources, and transmission capabilities that allow it to autonomously monitor cardiac pressure continuously without requiring external intervention. This self-service capability eliminates detection delays (reducing loss of time) while the minimally invasive implantation approach keeps risks manageable.
Solution Approach 2:
The patent replaces traditional mechanical or invasive monitoring methods with an implanted electronic sensor system that uses electrical and electronic mechanisms for continuous pressure monitoring. This substitution enables timely detection of heart failure symptoms (reducing loss of time) while the minimally invasive nature of the electronic implant reduces the harmful factors associated with more aggressive surgical approaches.
