AI Technical Summary

Technical Problem

Wounds, such as those resulting from endoscopic procedures, are difficult to close naturally and can lead to infection risks due to their size and location, especially when larger than the working area of the endoscope, making it challenging to use devices through the endoscope's channel.

Method used

A medical device with a closure element that can be deployed around the endoscope's end cap, utilizing shape-memory configurations like coils or knots, activated by photo, thermal, or electrical stimuli, to close wounds by being inserted and activated to contract around the wound, assisted by suction to displace tissue into the end cap.

Benefits of technology

Effectively closes wounds by approximating tissue edges, reducing the wound area, and promoting healing, while being adaptable to larger wounds and avoiding obstruction of the endoscope's working channel.

Abstract

To provide devices for closing a wound, such as a tissue defect resulting from an endoscopic mucosal resection or endoscopic submucosal dissection procedure.SOLUTION: A device for closing a wound includes a closure element 100 having a delivery configuration and a deployed configuration, the closure element configured to be disposed about an endcap 120 of an endoscope in the delivery configuration. A release filament 102 may have a distal end 102d releasably coupled to the closure element, and a proximal end extending within the endcap. The closure element may be configured to substantially close about the wound in the deployed configuration.SELECTED DRAWING: Figure 1B
