Abstract
A tubular prosthesis that includes a scaffolding formed by at least one scaffolding filament; a cover; and at least one controlled ingrowth feature constructed and arranged to abut an inner surface of a lumen wall when the prosthesis is implanted in the body lumen. The controlled ingrowth feature may extend inwards or outwards from the prosthesis outer surface. The controlled ingrowth feature may be formed by a scaffolding filament; by a separate filament; by the cover; and combinations thereof.
Claims20
A prosthesis for controlled tissue ingrowth when implanted in a body lumen comprises:
- a scaffolding extending from a first prosthesis end to a second prosthesis end, the scaffolding comprising;
- a cover;
- a controlled ingrowth feature constructed and arranged to abut an inner surface of a lumen wall when the prosthesis is implanted in the body lumen, the controlled ingrowth feature selected from the group consisting of protruding elements and dimples;
- wherein the controlled ingrowth feature is formed by a scaffolding filament;
- by a separate filament;
- by the cover;
- and combinations thereof.
A prosthesis constructed and arranged for controlled tissue ingrowth when implanted, the prosthesis comprising:
- a scaffolding;
- a cover extending over an outer surface of the scaffolding;
- and
- a controlled ingrowth feature forming a maximum of about 30% of an outer surface area of the prosthesis;
A prosthesis comprising:
- a mesh scaffolding, the mesh scaffolding having a scaffolding outer surface;
- a cover engaged to the scaffolding outer surface, the cover comprising a non-dimple cover section and a dimple cover section, the dimple cover section entirely surrounded by the non-dimple cover section.
