Abstract
A system configured to detach an interventional implant from a cardiac valve includes a guide catheter and a capture mechanism routable through the guide catheter. The capture mechanism comprises a capture hypotube with a container portion/space configured to receive an interventional implant connected to cardiac valve tissue. The capture mechanism also includes a cutting arm axially moveable relative to the capture hypotube. The capture hypotube and the cutting arm each include cutting elements that are brought together upon actuation of the cutting arm to thereby cut the cardiac valve tissue surrounding the interventional implant to free the implant from the cardiac valve.
