Abstract
The invention relates to a transcatheter heart valve replacement (A61F2/2412), and in particular a device and method for percutaneous annular plication and heart valve deployment for mounting a pressure actuated flow control sleeve, a pinch valve, as a replacement device for a heart valve, whereby the prosthesis has an atrial annular flange or cuff having one or more integral plication tissue anchors for engaging the valve annulus, wherein the is a reciprocating mechanical member that is compressed by pressurized working fluid within the heart during ventricular systole.
Claims13
A transcatheter heart valve replacement comprising:
- an asymmetric wire frame with an upper angled collar of scalloped diamond-shape cells forming an atrial flange;
- a middle ring defining a lumen connected to the atrial flange, the middle ring comprised of a plurality of diamond-shape cells;
- a reciprocating flow control member mounted on the middle ring and disposed within the lumen;
- and
- a plurality of tissue anchors, each tissue anchor mounted on the wire frame for engaging annular tissue;
- wherein the atrial flange has a steep angle of inclination at a septal region of the wire frame, and a shallower angle of inclination around anterior and posterior annular regions of the wire frame;
- wherein the wire frame has an inner covering of pericardial tissue, and an outer covering of a polyester material.
