Apparatus, system, and method for treating a regurgitant heart valve
First Claim
1. 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 the anchoring member is securely positioned within heart tissue associated with 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;
wherein after the anchoring member is secured in the heart chamber, blood is permitted to flow through at least a portion of the occluding member.

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.
