Abstract
A prosthetic heart value assembly comprising a prosthetic heart valve and a fixation band. The fixation band comprises a tubular frame and a tube. The tubular frame comprises longitudinally-extending members having hooks on their distal ends and fixation means on proximal ends, and a stabilizing laterally-extending member. The tube is positioned inside the longitudinally-extending members, a distal end of the tube being everted over the hooks. A sewing cuff is formed in the tube. The prosthetic valve is secured to the fixation band by suturing a prosthetic valve sewing cuff to a fixation band sewing cuff. The prosthetic valve and fixation band are advanced to the valve's seat. The fixation band's hooks are passed through the wall of the everted tube and into surrounding tissue and the fixation band's fixation means are deployed.
