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.
