Valve clip

Abstract

The invention relates to a valve clip. The valve clip includes a first valve clip and a second valve clip; the first valve clip is woven by titanium nickel alloy wires and includes a first clip body in an annular opening structure; the bottom inside the first clip body is connected to a steel cable structure; the second valve clip is made of stainless steel and includes a second clip body, two fixing supports, a fixing ring and a hardening pipe; the fixing ring is in a circular structure and fixedly connected to the bottom of the second clip body; the front ends of the fixing supports are respectively and fixedly connected to the end section of the second clip body, and the tail ends of the fixing supports are fixedly connected to the central position at the bottom of the fixing ring; andthe hardening pipe is arranged in the bottom of the second clip body and between the two fixing supports. The advantages of the valve clip are as follows: interventional therapy can be performed on the patients with mitral, tricuspid and aortic insufficiency in valvular heart diseases; the valve clip is simple in operation, small in trauma, fast in recovery and wide in indication.
