SYSTEMS AND METHODS FOR TREATING A DEFECTIVE CARDIAC VALVE HAVING ANTIMIGRATION FEATURES

Abstract

Apparatus and methods for repairing a cardiac valve, e.g., a tricuspid valve, are provided. The apparatus may include a prosthetic device coupled to an elongated support coupled to a stent configured to be implanted within a vessel, e.g., the superior vena cava, to suspend and maintain the prosthetic device within the cardiac valve. The support may include a proximal, delivery portion detachably coupled, in a delivery state, to a distal, implantable portion coupled to the prosthetic device. The prosthetic device may be formed of biocompatible material coupled to a frame, and may have prosthetic leaflets that allows blood to flow therethrough in one direction during diastole, but prevents blood regurgitation during systole. The stent further may include features configured to resist migration of the stent within the vessel, as well as to prevent in-folding of the stent during deployment.
