US 12,611,303 B2 · Transcatheter mitral valve prosthesis

Abstract

A prosthetic cardiac valve comprises an anchor having an atrial skirt, an annular region, and a ventricular skirt. The prosthetic valve also has a plurality of prosthetic valve leaflets each having a first end and a free end. The first end is coupled with the anchor and the free end is opposite the first end. The prosthetic cardiac valve has an open configuration in which the free ends of the prosthetic valve leaflets are disposed away from one another to allow antegrade blood flow therepast, and a closed configuration in which the free ends of the prosthetic valve leaflets engage one another and substantially prevent retrograde blood flow therepast. The anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring the prosthetic cardiac valve to a patient's heart.

Claims21

Dependent claims

A delivery system for a prosthetic heart valve, the system comprising:

a stationary inner guidewire shaft having a lumen extending therethrough;
a stationary hub shaft over the inner guidewire shaft and having a plurality of prosthesis engagement slots in an outer surface of and adjacent to a distal end of the hub shaft;
a movable bell shaft over the hub shaft and configured to cover the plurality of slots on condition that the bell shaft is disposed thereover;
a movable sheath over the bell shaft and configured to hold one or more portions of the prosthetic valve in a collapsed configuration between the sheath and the bell shaft on condition that the sheath is disposed thereover;
a handle adjacent a proximal end of the delivery system and having an actuator configured to move the bell shaft and the sheath to modulate engagement of the prosthetic valve with the delivery system;
and
a pin lock coupled to the handle and configured to prevent proximal retraction of the sheath.
