Abstract
This document provides devices and methods for repairing a prolapsing mitral valve leaflet using minimally invasive catheter based approaches. For example, percutaneous procedures that involve folding and securing a segment of a prolapsing leaflet onto or pulling and securing a segment of a prolapsing leaflet through part of the greater mitral valve leaflet are provided. In some cases, artificial chordae are installed to stabilize and maintain desired orientation of the leaflets.
Claims9
A method for treating mitral valve prolapse, wherein said method comprises:
- (a) approaching a prolapsed leaflet using a minimally invasive catheter technique, (b) capturing an edge segment of the prolapsed leaflet using a grasping device, (c) repositioning the edge segment onto an atrial or ventricular surface of a body of the prolapsed leaflet, and (d) securing the edge segment to the atrial or ventricular surface of the body of the prolapsed leaflet using an attachment device, wherein the repositioning creates a fold in the prolapsed leaflet that results in tissue from the body of the prolapsed leaflet becoming a reconfigured edge of the prolapsed leaflet, wherein the reconfigured edge made of tissue from the body of the prolapsed leaflet apposes and coapts with an opposing leaflet to reduce mitral valve regurgitation and a longitudinal axis of the fold is parallel to a line of coaptation between the prolapsed leaflet and the opposing leaflet.
