APPARATUS, SYSTEM, AND METHOD FOR TREATING A REGURGITANT HEART VALVE
First Claim
1. An apparatus for treating regurgitation of blood through a diseased heart valve having at least two leaflets, said apparatus comprising:
- a lollipop-shaped body member having a proximal end portion, a distal end portion, and an intermediate portion extending between said proximal and distal end portions;
said intermediate portion including an expandable occluding member having an adjustable diameter so that, during at least a portion of the cardiac cycle, at least one of the heart leaflet coapts with a portion of said occluding member to mitigate or prevent regurgitation of blood through the diseased heart valve;
said proximal end portion being physically connected to said occluding member and including a connecting mechanism for operably mating with an adjustment member for adjusting the position and diameter of said occluding member within the diseased heart valve;
said distal end portion including an anchoring member for securing said apparatus in a heart chamber containing the diseased heart valve.

Abstract
An apparatus for treating regurgitation of blood through a diseased heart valve having at least two leaflets includes a lollipop-shaped body member having a proximal end portion, a distal end portion, and an intermediate portion extending between the end portions. The intermediate portion includes an expandable occluding member having an adjustable diameter so that, during at least a portion of the cardiac cycle, at least one of the heart leaflet coapts with a portion of the occluding member to mitigate or prevent regurgitation of blood through the diseased heart valve. The proximal end portion is physically connected to the occluding member and includes a connecting mechanism for operably mating with an adjustment member for adjusting the position and diameter of the occluding member within the diseased heart valve. The distal end portion includes an anchoring member for securing the apparatus in a heart chamber containing the diseased heart valve.

8. A system for treating regurgitation of blood through a diseased heart valve having at least two leaflets, said system comprising:
-
a lollipop-shaped body member having a proximal end portion, a distal end portion, and an intermediate portion extending between said proximal and distal end portions; and an adjustment member including an elongated body having a proximal control end and a distal connecting end for mating with a connecting mechanism of said body member; said intermediate portion including an expandable occluding member having an adjustable diameter so that, during at least a portion of the cardiac cycle, at least one of the heart leaflet coapts with a portion of said occluding member to mitigate or prevent regurgitation of blood through the diseased heart valve; said proximal end portion being physically connected to said occluding member and including said connecting mechanism for operably mating with said adjustment member and for adjusting the position and diameter of said occluding member within the diseased heart valve; said distal end portion including an anchoring member for securing said apparatus in a heart chamber containing the diseased heart valve. - View Dependent Claims (9, 10)

11. A method for treating regurgitation of blood through a diseased heart valve having at least two leaflets, said method comprising the steps of:
-
providing a system comprising an apparatus and an adjustment member, the apparatus including a lollipop-shaped body member having a proximal end portion, a distal end portion, and an intermediate portion extending between the distal end portions, the intermediate portion including an expandable occluding member having an adjustable diameter, the proximal end portion being physically connected to the occluding member and including a connecting mechanism that is operably connected to the adjustment member, and the distal end portion including an anchoring member; securing the anchoring member in a heart chamber containing the heart valve; operating the adjustment member so that at least a portion of the occluding member is securely positioned within the diseased heart valve; and operating the adjustment member to increase or decrease the diameter of the occluding member so that at least one of the diseased heart valve leaflets coapts with the occluding member during the cardiac cycle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
