Repositionable Over-the-Scope Clip for Visual Tissue Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic closure devices, particularly over-the-scope clips, are difficult to use, time-consuming, and often insufficient for certain perforations or anatomies, as they require deployment without direct visualization and cannot be easily repositioned.
Innovation Solution
A clipping system with a clip that can be mounted over an endoscope adapter, featuring a base portion and movable arms, allowing for an insertion, initial deployed, and review configurations, enabling visual confirmation and repositioning before final deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current over-the-scope clips are deployed without direct visualization, then the deployment process is simplified, but the precision of clip placement deteriorates
Solution Approach 1:
The clip is designed with dynamic repositioning capability, allowing it to be moved between deployed and retracted positions. The clip can be retracted proximally over the adapter and then redeployed distally to the target tissue, enabling the operator to visualize the clip placement and adjust position as needed while maintaining operational simplicity.
Solution Approach 2:
The clip is retracted to a review configuration where it can be visualized before final deployment. This preliminary visualization allows the operator to confirm proper positioning and tissue engagement before the clip is released from the adapter, ensuring precision without complicating the overall deployment process.
2Device complexity
If current over-the-scope clips are deployed without repositioning capability, then the device structure is simplified, but the adaptability to different anatomies and perforations deteriorates
Solution Approach 1:
The clip incorporates dynamic repositioning through its connection to the adapter and control member. The clip can be retracted proximally over the adapter and then deployed distally to different positions along the GI tract, providing adaptability to various anatomies and perforation locations without significantly increasing device complexity.
Solution Approach 2:
The device is segmented into distinct functional components: the adapter mounted on the endoscope, the clip with movable arms, and the control member. This segmentation allows the clip to be independently repositioned relative to the adapter, enabling adaptation to different tissue locations while keeping each component's structure relatively simple.
3Ease of operation
If the clip is held in a fixed deployed position, then the operation is simplified, but the ability to visualize and confirm proper placement deteriorates
Solution Approach 1:
The clip is designed with dynamic positioning capability, allowing it to be retracted proximally over the adapter to a review configuration where it can be directly visualized through the endoscope. This dynamic movement enables the operator to confirm proper placement while maintaining operational simplicity, as the same control mechanism used for deployment also enables retraction for visualization.

AI summary
A system includes a clip, a first control member, and an adapter including a channel extending from a proximal end to a distal end. The clip includes a base portion mounted over a periphery of the adapter and arms extending distally from the portion. The arms are movable relative to one another between insertion and initial deployed configurations. The first member is releasably coupled to the portion and is movably connected to the adapter so that a longitudinal movement of the first member relative to the adapter moves the clip between the insertion configuration, the initial deployed configuration, and a review configuration. The first member is operable to retract the clip proximally over the adapter toward the insertion configuration so that the arms is forced open as the clip is retracted over the adapter freeing the clip from tissue on which it had been clipped.
