Abstract
A prosthetic heart valve comprising a frame which includes outer and inner bands and a plurality of wire-like members interlocked with the bands and forming the tip portions of commissure supports. The bands are covered with outer and inner jackets, and valve leaflets are attached to the frame and extend over a distal edge of the bands. The ends of the jackets form flexible, resilient fingers which extend between the distal edge and the valve leaflets to shield the valve leaflets from the distal edge.
