Abstract

A method of implanting a universal heart valve prosthetic anchor device for receipt of a mating occluder. The anchor device includes a pair of rings axially shiftable from a retracted to a deployed position. The anchor device further formed with a plurality of flexible retaining elements received within the anchor rings and which are capable of laterally downwardly outward movement upon deployment of the rings. The deployment tool includes an elongated tubular housing mounted at its distal end with radially outwardly diverging tines for reversible engagement with the anchoring rings. A wire is telescoped through the tines for actuation of the fork thereby causing deployment of the anchoring rings. Once placed at the desired location within the heart muscle, the deployment tool is actuated causing the anchor device to shift axially thereby causing the retainers to deploy outwardly and upwardly to secure the valve anchor in place at the heart valve annulus shelf.

Claims

1. A method for implanting a heart valve anchor in a heart annulus comprising the steps of:

selecting an anchor device for receipt through said annulus including spaced apart ring elements shiftable axially relative to one another from recessed to deployed positions and a retainer retained between said ring elements operable upon said ring elements being shifted from a retainer recessed position to a retainer deployed position projecting radially outwardly;

accessing an artery of said patient and inserting said anchor device therethrough to position it in said annulus; and

shifting said ring elements axially relative to one another to said deployed position by rotating them relative to one another to shift said retainer to said retainer deployed position.

3. The method for implanting a heart valve anchor as set forth in claim 1 or 2, wherein:

said step of selecting said anchor device includes selecting said anchor device to include a radially outwardly projecting stop ring on a proximal end thereof, and

said step of inserting said anchor device includes inserting it sufficiently far to position said stop ring on a proximal side of said annulus.

4. The method for implanting a heart valve anchor as set forth in claim 1 or 2, that further includes the steps of:

after shifting said retainer to said retainer deployed position, shifting said ring elements to said recessed position to shift said retainer from said retainer deployed position to said retainer recessed position.

5. The method for implanting a heart valve anchor as set forth in claim 1 or 2, that further includes the step of:

imbedding said retainer in said annulus.

6. The method for implanting a heart valve anchor as set forth in claim 1 or 2, wherein:

said step of inserting said device includes selecting an elongated introduction tool having a semi-rigid tubular tool housing and an elongated deployment rod projecting therethrough and coupling the distal end of said tool housing with one of said ring elements and the distal extremity of the other ring element with the other of said ring elements.

2. A method for implanting a heart valve anchor in a heart annulus comprising the steps of:

selecting an anchor device for receipt through said annulus including spaced apart ring elements threaded to one another and shiftable axially relative to one another from recessed to deployed positions and a retainer retained between said ring elements operable upon said ring elements being shifted from a retainer recessed position to a retainer deployed position projecting radially outwardly;

accessing an artery of said patient and inserting said anchor device therethrough to position it in said annulus; and

shifting said ring elements axially relative to one another to said deployed position by rotating said ring elements relative to one another to shift them axially relative to one another to shift said retainer to said retainer deployed position.
