Patent number: 9161837Abstract: 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.Type: GrantFiled: July 27, 2012Date of Patent: October 20, 2015Assignee: The Cleveland Clinic FoundationInventor: Samir Kapadia

Patent number: 8597225Abstract: A method is provided for increasing blood flow in or about a cardiac structure to prevent thrombosis. One step of the method includes providing an implantable sprayer having an elongated tubular body with proximal and distal end portions. The distal end portion includes at least one opening and an anchoring mechanism. The distal end portion of the implantable sprayer is inserted into a cardiac chamber that includes the cardiac structure. The anchoring mechanism is then deployed so that the distal end portion of the implantable sprayer is secured in or about the cardiac structure. Next, the proximal end portion is anastomosed with an artery so that blood flows through the elongated tubular body of the implantable sprayer and is sprayed out of the at least one opening to continuously circulate blood in or about the cardiac structure.Type: GrantFiled: July 26, 2011Date of Patent: December 3, 2013Assignee: The Cleveland Clinic FoundationInventor: Samir Kapadia
