Abstract
A composite stent-graft tubular prosthesis includes a non-continuous tubular body formed of polytetrafluoroethylene components, providing axial and circumferential compliance to said prosthesis and a circumferentially distensible stent.
Claims20
An implantable composite intraluminal prosthesis comprising,
- a circumferentially distensible tubular support structure having opposed inner and outer surfaces;
- and
- a longitudinally;
- non-continuous tubular body on at least one surface of the support structure, comprising PTFE components, each having a length and a width, said length being greater than said width;
- said components being spirally wound, and positioned on said at least one surface.

A method of making an implantable composite intraluminal prosthesis, comprising:
- a) providing a circumferentially distensible tubular support structure having opposed inner and outer surfaces;
- b) providing at least two ePTFE components, each having a length greater than its width;
- and,
- c) spirally winding the components to form a non-continuous tubular body on at least one surface of the tubular support structure to make a composite with a support structure side and an ePTFE side.
