Abstract
A suture member having first and second ends longitudinally separated by a suture midsection is provided. The suture member is fastened to the prosthetic structure with at least one of the first and second ends being located adjacent a tissue-contacting surface of the prosthetic structure. At least one terminal feature is formed on at least one of the first and second ends located adjacent the tissue-contacting surface of the prosthetic structure. The body tissue is engaged with at least one terminal feature to anchor the prosthetic structure to the body tissue. An apparatus for anchoring a prosthetic structure to a body tissue is also provided.

A method of anchoring a prosthetic structure to a body tissue, the method comprising the steps of:
- providing a suture member having first and second ends longitudinally separated by a suture midsection;
- fastening the suture member to the prosthetic structure with at least one of the first and second ends being located adjacent a tissue-contacting surface of the prosthetic structure;
- forming at least one terminal feature on at least one of the first and second ends located adjacent the tissue-contacting surface of the prosthetic structure;
- and
- engaging the body tissue with at least one terminal feature to anchor the prosthetic structure to the body tissue.
An apparatus for anchoring a prosthetic structure to a body tissue, the apparatus comprising:
- a suture member having first and second ends longitudinally separated by a suture midsection;
- the suture member being connected to the prosthetic structure;
- at least one of the first and second ends being located adjacent a tissue-contacting surface of the prosthetic structure;
- and
- at least one terminal feature associated with at least one of the first and second ends and adapted to engage the body tissue for anchoring the prosthetic structure to the body tissue.
