System and method for percutaneous mitral valve repair

摘要

A system for minimally invasive repair of a mitral valve including a catheter, a capture body and a surgical fastener. The capture body includes legs extending from a center portion, and is self-transitionable from a collapsed arrangement to a normal arrangement in which the legs extend in a common wind direction. The fastener has a self-closing clip forming a loop in an undeflected arrangement. In a delivery state, the capture body and fastener are disposed within the catheter and forced to the collapsed and deflected arrangements, respectively. In a capture state, the capture body legs are distal the catheter and self-assume the normal arrangement for capturing chordae. In a release state, the fastener is released from the catheter and the clip self-transitions toward the undeflected arrangement for securing the mitral valve leaflets.
