Percutaneously deliverable heart valve
First Claim
1. A foldable heart valve prosthesis to replace a diseased valve of a patient comprising:
- a support structure with a diameter, wherein the support structure is foldable to a smaller diameter, the support structure comprising a plurality of crossbar frames, wherein each crossbar frame has a plurality of crossbars connected at an end of each crossbar;
a flexible tissue heart valve with a plurality of valvular leaflets attached to said support structure; and
a plurality of slidable ring connectors, wherein at least a slidable ring connector encircles a first crossbar from a first crossbar frame and a second crossbar from a second crossbar frame configured to coupling the first and the second crossbars.

23. A method for minimally invasively delivering a foldable heart valve prosthesis into a patient, the foldable heart valve prosthesis comprising a support structure with a diameter, wherein the support structure is foldable to a smaller diameter, the support structure comprising a plurality of crossbar frames, wherein each crossbar frame has a plurality of crossbars;
- a flexible tissue heart valve with a plurality of valvular leaflets attached to said support structure; and
a plurality of slidable ring connectors, wherein at least a slidable ring connector encircles a first crossbar from a first crossbar frame and a second crossbar from a second crossbar frame configured to coupling the first and the second crossbars;
said method comprising;
folding said support structure with the attached flexible tissue heart valve inside a lumen of a delivery apparatus;
delivering said delivery apparatus to a target valvular annulus of the patient;
unfolding said support structure to deploy said foldable heart valve prosthesis in place; and
coupling the crossbars by sliding the slidable ring connector to an appropriate location of the crossbars. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
- a flexible tissue heart valve with a plurality of valvular leaflets attached to said support structure; and
-
47. A method for minimally invasively delivering a foldable heart valve into a patient, the foldable heart valve comprising a support structure having a plurality of crossbars and a plurality of slidable ring connectors;
- said method comprising;
folding said valve within a lumen of delivery means for delivering said valve to a target valvular annulus of the patient;
unfolding said valve in place by a balloon catheter, wherein a differentially expandable balloon of the balloon catheter is configured to expand the folded heart valve into an oval unfolded valve; and
coupling the crossbars by sliding the slidable ring connector to an appropriate location of the crossbars. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54)
