Release mechanism for over the scope clip
The clipping system allows for low-force decoupling and repositioning of over-the-scope clips, addressing the high-separation force issue in current systems, enhancing procedural control and reducing damage risks.

AI Technical Summary
Technical Problem
Current over-the-scope clips require high forces to separate from the adapter, making repositioning difficult and potentially damaging the clip or adapter, and lack a mechanism to allow reopening and repositioning without breaking a frangible member.
Method used
A clipping system with a release member that withstands internal forces during deployment and reopening, allowing the clip to be decoupled from the adapter using a low release force, enabling repositioning and final deployment.
Benefits of technology
Enables the clip to be reopened and repositioned multiple times without damaging the clip or adapter, improving procedural control and reducing the risk of failure during repositioning.

Abstract
A clipping system includes an adapter, a clip, a coupling, and a release member. The adapter includes a distal portion over which the clip is mounted. Jaws of the clip move between being separated to receive tissue and drawn to grip the tissue. The coupling includes a channel and a recess formed in a side of the coupling. The recess receives a side portion of the clip therewithin and accessible by a window in the side. The member extends partially through the channel and includes a retaining portion positioned within the recess between the window and the side portion. The member moves to a release position to withdraw from the recess to permit the side portion to exit the recess through the window to decouple the clip from the system.
