PROSTHETIC VALVE WITH ANTI-PIVOTING MECHANISM

摘要

A prosthetic valve for implanting in a patient's native valve has a self-expanding frame that comprises a first end, a second end opposite the first end, an anterior portion, and a posterior portion. The self-expanding frame has an expanded configuration adapted to engage tissue at a treatment site, and a collapsed configuration adapted to be delivered to the treatment site. The expandable frame also comprises a self-expanding atrial skirt near the second end, a self-expanding ventricular skirt near the first end, a self-expanding annular region disposed between first and second ends, a first self-expanding anterior tab disposed on the anterior portion, and a self-expanding foot coupled to the posterior portion and extending radially outward. The foot has an outer surface for engaging the tissue thereby facilitating anchoring of the prosthetic valve and minimizing or preventing rotation of the prosthetic valve.

1. A prosthetic valve for implanting in a native valve of a patient, said prosthetic valve comprising:
a self-expanding frame having a first end, a second end opposite the first end, an atrial region near the second end, a ventricular region near the first end, an anterior portion, and a posterior portion, wherein the self-expanding frame has an expanded configuration and a collapsed configuration, the expanded configuration adapted to engage tissue at a treatment site, and the collapsed configuration adapted to be delivered to the treatment site, and wherein the expandable frame comprises: a self-expanding atrial skirt disposed in the atrial region; a self-expanding ventricular skirt disposed in the ventricular region; a self-expanding annular region disposed between the atrial region and the ventricular region; a first self-expanding anterior tab disposed on the anterior portion of the self-expanding frame in the ventricular region; and a self-expanding foot coupled to the ventricular region, wherein the foot is disposed in the posterior portion and extends radially outward from the self-expanding frame and has an outer surface for engaging the tissue thereby facilitating anchoring of the prosthetic valve and minimizing or preventing rotation of the prosthetic valve.
