Percutaneously delivered heart valve and delivery means thereof
First Claim
1. A method for minimally invasively delivering a foldable heart valve prosthesis into a patient, the foldable heart valve prosthesis comprising a twistedly foldable support element and a heart valve releasably secured to said support element, said method comprising:
- twistedly folding said support element with the secured heart valve within a lumen of a delivery apparatus by twisting and folding said support element by compressing an expanding metallic frame with intercrossing linear bars;
delivering said delivery apparatus to a target valvular annulus of the patient; and
un-twisting said support element to unfold and deploy said heart valve in place.

Abstract
This invention discloses a percutaneous delivered heart valve and delivery means thereof, wherein the percutaneous delivered heart valve is a twistedly foldable heart valve prosthesis comprising a generally cylindrical support element with a diameter, wherein the support element is twistedly foldable to a smaller diameter, a flexible heart valve with a plurality of valvular leaflets releasably attached to said support element, and a receptacle having a plurality of connecting members secured to the cylindrical support element, wherein the receptacle is releasably matched to an expanding element capable of untwisting the receptacle adapted for un-twisting and unfolding said heart valve.

24. A twistedly foldable heart valve system to replace a diseased valve of a patient comprising:
-
a generally cylindrical support element with a diameter, wherein the support element is twistedly foldable and compressible to a smaller diameter; a flexible heart valve with a plurality of valvular leaflets releasably attached to said support element; and a receptacle having a plurality of connecting members secured to the cylindrical support element, wherein the receptacle is releasably attached and matched to an expanding element, the expanding element further being capable of matching and untwisting the receptacle adapted for un-twisting and unfolding said heart valve; wherein the flexible heart valve is made of tissue material; wherein said flexible heart valve is an atrioventricular valve comprising a plurality of cusps, each cusp having a semicircular tip edge and two generally straight side edges that are joined at said semicircular tip edge, wherein each of said straight side edges is trimmed and configured at an angle of about less than 20 degrees from a reference central longitudinal line of said cusp.
