Abstract
A graft (1) having a band of fibrous material (13) on an outer surface thereof adjacent its proximal end (9). The band of fibrous material extends circumferentially around the graft to promote adhesion. The band can be continuous around the proximal end of the graft. The band can be formed from a patch of fibrous material, cut or loop pile velour, by fibres woven or knitted into the material of the graft or by brushing of material of the graft to raise fibres of the material of the graft. The band of fibrous material has a length of from 5 mm to 15 mm along the length of the graft.
Claims15
A stent graft comprising:
- a tubular graft having a distal end, a proximal end, and an outer surface;
- at least one expandable stent disposed on said tubular graft;
- and
- a band of fibrous material on said outer surface and adjacent at least one of said distal end and said proximal end of said tubular graft, said band of fibrous material extending circumferentially around said graft.
A stent graft comprising:
- a tubular graft having an outer surface and a proximal end;
- at least one expandable stent disposed on said tubular graft;
- and
- a continuous band of velour material adjacent said proximal end of said tubular graft, said continuous band of velour material extending circumferentially around said graft.
A stent graft adapted for insertion into an internal lumen of a patient to be incorporated therein, the stent graft comprising a substantially tubular body providing a fluid flow path and having a periphery defined by a biocompatible relatively impervious material wall, the wall having a proximal portion including a continuous external circumferential band of a fibrous biocompatible material.
