Heart valve treatment device and method
First Claim
1. A heart valve therapeutic device for implantation in a patient having a heart and a native heart valve, the heart valve therapeutic device comprising:
- a prosthetic valve element comprising leaflets arranged so that in use blood flows through the prosthetic valve element, anda support comprising an elongated anchor having an elongated body with a length, a proximal region, and a distal region, the distal region coupled to the prosthetic valve element to maintain the prosthetic valve element within the native heart valve, the length of the elongated body selected to extend from the distal region out of the heart and percutaneously through a blood vessel coupled to the heart, the elongated anchor having a variable and lockable shape and exhibiting a stiffness sufficient to hold the lockable shape to suspend and maintain the prosthetic valve element within the native heart valve without contacting either an atrial wall or a ventricular wall of the heart,wherein the support is configured to allow adjustment of axial position and of orientation of the prosthetic valve element and wherein the prosthetic valve element comprises a ring, and said ring is on chords extending from a coupler on the elongated anchor.

Abstract
A heart valve therapeutic device has an elongate anchor wherein the anchor has a stiffness to hold its shape and location to support the valve element. The anchor may have a stylet or a shaped or stiff collar arranged to provide a desired shape to the anchor and it may be lockable. A prosthetic valve element has leaflets and is supported on the anchor by coupler at a desired location. There is an actuator for changing relative axial position of the proximal and distal couplers on the anchor. The anchor stiffness may be sufficient to provide sufficient support to resist axial forces from the ventricle in use without necessarily having a fixing element engaging heart tissue. The prosthetic leaflets may extend proximally and radially outwardly, so that there is excellent co-apting of the native leaflets (NL) against the prosthetic leaflets.
