Abstract
The present invention relates to medical devices and in particular to frameless grafting prostheses and methods of making and using such devices. The frameless grafting prostheses include a stiffening member useful in the attachment of the frameless grafting prostheses to a wall of a body lumen.
Claims20
A frameless grafting prosthesis for implantation in a body lumen having a lumen wall, the frameless grafting prosthesis comprising at least one shaped valve cusp comprising:
- a valve body having a top edge, a base edge, and side edges extending from the base edge to the top edge,
- at least one anchoring element attached to the base edge, and
- a stiffening member positioned within the valve body and having first and second ends, the first end directly contacting the anchoring element and the second end comprising a pushing surface, the stiffening member extending from the anchoring element to the top edge of the valve body,
- wherein the stiffening member is less flexible than the valve body and is adapted to allow a force sufficient to attach the anchoring element to the lumen wall to be transmitted from the pushing surface to the anchoring element.
