FIXATION BAND FOR AFFIXING A PROSTHETIC HEART VALVE TO TISSUE

摘要

A fixation band (155) for affixing a prosthetic heart valve to tissue, the fixation band (155) comprising: a structure having a proximal end and a distal end in opposition to one another, and a lateral region between the proximal end and the distal end, wherein the prosthetic heart valve is attached to one of the proximal end and the distal end of the structure; a plurality of barbs (165) selectively configurable between a first position and a second position, the barbs (165) being contained within a peripheral boundary of the lateral region of the structure in the first position, and the barbs (165) being extended from the peripheral boundary of the lateral region of the structure in the second position; and an actuator for selectively moving the plurality of barbs (165) between the first position and the second position.
