Abstract
The invention disclosure provides a composite compliant vascular graft for implantation in a host, which graft includes a tubular body having a lumen and a tubular wall surrounding the lumen made of a composite material, which is adapted to permit expansion of the tubular body from a native state to an expanded state and then to return to the native state in response to pressure changes in the lumen, which includes a mechanical component which is adapted to limit the expanded state, and a compliant component which is adapted to bias return of the tubular body to the native state.

A composite compliant vascular graft material for replacement of a portion of a vessel, comprising:
- a tubular body extending between a proximal end and a distal end, the tubular body having a lumen and comprising a composite compliant material adapted to permit expansion of the tubular body from a native state to an expanded state and then to return to the native state in response to pressure changes in the lumen, the composite compliant material comprising:
- a mechanical component adapted to limit the expanded state;
- and
- a compliant component adapted to promote the return of the tubular body to the native state, wherein:
- the composite compliant material has anisotropic mechanical properties configured to facilitate radial and longitudinal expansion of the tubular body to the expanded state and radial and longitudinal expansion recoil to the native state in response to the pressure changes.
