Abstract
The present disclosure provides an implantable medical device comprising a composite graft material including a first biologic component, such as an acellular tissue matrix, and a second non-biologic component.
Claims24
An implantable medical device comprising:
- a plurality of first elongate non-biologic elements, at least a portion of which are under a tensile or compressive stress prior to implantation;
- at least one biologic component surrounding at least a portion of the plurality of first elongate elements;
- and
- at least one second elongate non-biologic element, wherein the at least one second element secures at least one end portion of the plurality of first elongate non-biologic elements.
1 more element
The implantable medical device of clam 17, wherein the at least one second elongate element forms a pitched portion for engaging an anchoring screw.
A method of making a composite prosthesis comprising:
- providing a plurality of first elongate non-biologic elements;
- applying a load to the plurality of first elongate non-biologic elements;
- covering at least a portion of the plurality of first elongate non-biologic elements with at least one biologic component;
- and
- securing the plurality of first elongate non-biologic elements with at least one second elongate non-biologic element.

22-44. (canceled)
A method of making a composite prosthesis comprising:
- providing at least one non-biologic core;
- applying a tensile load to the non-biologic core;
- and
- disposing at least one biologic element about the at least one non-biologic core, the at least one biologic element comprising a biomatrix;
- wherein
- the at least one non-biologic core bears a greater tensile load at a time of implantation than the at least one biologic element, while transmitting strain to the at least one biologic element;
- and
- after implantation, the at least one non-biologic core gradually weakens, thereby transferring additional tensile load to the at least one biologic element.
