AI Technical Summary

Technical Problem

Current transcatheter valve clipping procedures require the implantation of multiple valve clipping devices to achieve sufficient treatment width, which increases the operation time and risks, especially for elderly patients.

Method used

A valve clamping device is designed, comprising a fixing base, first and second clamping members, and an expansion arm. The expansion arm consists of first and second parts connected to each other, which are used to assist in supporting the valve leaflets and enhance the clamping effect.

Benefits of technology

The design of the expansion arm enables a single clamping device to achieve the treatment width of multiple clamping devices, reducing operation time and risk, and improving the safety and effectiveness of the operation.

Abstract

This invention discloses a valve clamping device, comprising a fixing base; a first clamping member and a second clamping member; and an expansion arm. The first and second clamping members are pivotally connected to the fixing base and can be opened or closed relative to each other. When the first and second clamping members are closed relative to each other, they can clamp the valve. The deformable expansion arm includes a first portion and a second portion. The first portion connects to the first clamping member and / or the second clamping member, and the second portion connects to the first portion. Both the first and second portions extend beyond the first and / or the second clamping member to assist in supporting the valve leaflet. This invention also discloses a valve repair instrument including the valve clamping device.
