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.
Claims16
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 comprising a biomatrix surrounding at least a portion of the plurality of first elongate non-biologic 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;
- wherein the plurality of first elongate non-biologic elements have a higher load capacity than the at least one biologic component at the time of implantation;
- and
- wherein the at least one biologic component has a higher load capacity than the plurality of first elongate non-biologic elements after implantation and following growth of native cells within the biomatrix.
