Novel Two Piece Replacement Heart Valve Delivered via Transcatheter
Children's Hospital Boston
posted on 06/26/2010
Drs. Lock and Nugent have modeled a two piece replacement heart valve apparatus that is administered via a catheter. The heart valve apparatus includes a stent and a valve frame having a substantially cylindrical body defining a lumen. The valve frame includes a plurality of curved wire pairs attached to a cylindrical body. Each curved wire pair includes an inner curved wire and an outer curved wire. Also, the wire frame has a plurality of leaflets. Each leaflet is attached to a respective inner curved wire and extends over an outer curved wire to position the body of the leaflet within the lumen of the valve frame (CMCC 801).|| In addition to the apparatus above, Drs. Drs. Lock and McElhinney have added a docking station for positioning within the lumen. The docking station includes a diaphragm adapted to have an open and a closed position, which provides a temporary control mechanism for preventing free regurgitation during the time period between the deployment of the docking station and the deployment of the valve frame, and a sealing mechanism for preventing paravalvar leakage (CMCC1468)
