摘要:
A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. Interlocking members or flexible loops are included to limit expansion of the valve to one or two valve sizes, for example, with a 2-mm gap between each valve size. The valve may include an internal structural band with overlapped free ends having structure for limiting expansion, or external loops of suture may be added to the fabric covering which limits expansion.
