Linear Tissue Clipping Device for Parallel Access and Defect Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tissue recruitment and hemostatic devices are difficult to position and operate effectively when accessing target tissue from a non-perpendicular approach, leading to inefficiencies in tissue recruitment and closure.
Innovation Solution
A linear tissue clipping device with a distal and proximal arm assembly, actuated by a drive element, allows for tissue clipping in a parallel direction, enabling effective closure of defects and recruitment of tissue, even in hard-to-reach locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional tissue recruitment devices are operated from a perpendicular approach, then the device structure can be simple, but the device cannot access hard-to-reach locations and procedural efficiency decreases
Solution Approach 1:
The patent transitions from perpendicular (vertical) tissue recruitment to parallel (lateral) tissue recruitment by reorienting the arms to move along the luminal wall surface rather than from above, enabling access to previously unreachable locations while maintaining structural feasibility
2Productivity
If conventional hemostatic devices are used for tissue closure, then the device design can be simple, but multiple devices are required for larger defects increasing procedural time
Solution Approach 1:
The patent combines multiple tissue recruitment and closure functions into a single integrated device with coordinated arms that can recruit and close tissue in one procedure, eliminating the need for multiple separate devices and reducing procedural time
3Reliability
If conventional perpendicular approach is used for tissue recruitment, then positioning is straightforward, but tissue recruitment effectiveness decreases for certain anatomical locations
Solution Approach 1:
The patent employs dynamic, articulated arms that can flex and adjust their orientation to follow the contours of the luminal wall, allowing the device to adapt to various anatomical geometries while maintaining effective tissue contact and recruitment

AI summary
A tissue clipping device for clipping tissue and methods of using the same. The device includes a tissue clipping assembly for clipping tissue and a drive assembly operable to control the operation of the tissue clipping assembly. The tissue clipping assembly includes a distal arm that is linearly extendable and retractable to clip tissue. The tissue clipping assembly may be decoupled from the drive assembly after tissue is clipped. Additional clipping assemblies may be deployed with the drive assembly to close larger defects.
