Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to effectively anchor sensing devices to gastrointestinal tissue for extended physiological signal measurement, as they lack integrated sensing capabilities and reliable tissue attachment mechanisms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical tissue attachment device is used, then tissue anchoring is achieved, but physiological signal sensing capability is lost
Solution Approach 1:
The patent combines a mechanical tissue anchoring device with physiological signal sensing capabilities into a single integrated system. The clamp assembly that provides mechanical attachment to tissue also incorporates sensors that contact the tissue to detect physiological signals, thereby simultaneously achieving both reliable anchoring and signal sensing functions.
Solution Approach 2:
The device is designed to perform multiple functions: it mechanically anchors to tissue through the clamp assembly while simultaneously sensing physiological signals through integrated sensors. This multi-functional design allows a single device to serve both as an attachment mechanism and a diagnostic tool.
2Measurement precision
If a sensor is integrated into the tissue clip, then physiological signal measurement is enabled, but device complexity increases
Solution Approach 1:
The device is divided into distinct functional modules: a clamp assembly for mechanical attachment and a sensor assembly for physiological signal detection. This segmentation allows each component to be optimized independently while maintaining overall system integration, managing complexity through modular design.
3Ease of operation
If the clamp is made detachable at the frangible section, then device retrieval is simplified, but structural integrity is reduced
Solution Approach 1:
The cable is pre-designed with a frangible section that is intentionally weaker than other parts of the cable. This preliminary weakness is strategically placed to allow controlled detachment at a specific point, enabling easy device retrieval while maintaining sufficient structural integrity during normal operation and deployment.

AI summary
An integrated physiological monitoring and tissue anchoring device is provided. The device includes a detachable clamp at the distal portion that includes a sensor configured to sense a physiological parameter from the gastrointestinal tract. A handle at the proximal portion of the device is configured to actuate the clamp into a closed configuration in which gastrointestinal tissue is grasped by the clamp. A cable connects the handle to the clamp and has a frangible section near the clamp such that the clamp is detachable from the cable at the frangible section.
