The present invention provides a vascular prosthesis which comprises a braided tubular fabric comprising a plurality of braid layers wherein each layer includes at least one interlocking yarn which extends from that layer into another layer to form an interlock therewith. In one aspect of the invention, the plurality of braid layers may include a substantially non-absorbable first surface layer and a substantially resorbable second surface layer. |

DETAILED DESCRIPTION We claim: 1.
A prosthetic device, comprising: an implantable three-dimensional braided tubular structure having a plurality of braided layers including an inner surface substantially formed of resorbable yarn and an outer surface substantially formed of non-absorbable yarn wherein each layer includes at least one interlocking yarn which extends into another layer to form an interlock therewith whereby said device maintains its structural integrity as said resorbable yarn is resorbed.
2.
The prosthetic device according to claim 1, wherein said resorbable material comprises biologically resorbable yarns.
3.
The prosthetic device according to claim 2, wherein said yarns are selected from the group consisting of catgut, reconstituted collagen, polyglycolic acid, polydioxanone and poly(glycolide-trimethylene carbonate).
4.
The prosthetic device according to claim 1, wherein said structure further includes at least one intermediate layer between said surface layers.
5.
The prosthetic device according to claim 1, further comprising non-absorbable external support means surrounding said structure.
6.
The prosthetic device according to claim 5, wherein said support means includes at least one wrap forming a helical path around the exterior of said structure.
7.
The prosthetic device according to claim 6, wherein said wrap is formed of an elongate textile structure having a substantially high bending modulus.
8.
The prosthetic device according to claim 6, wherein said wrap is formed of monofilament yarns having a substantially high denier.
9.
The prosthetic device according to claim 6, wherein said wrap is formed of multifilament yarns having a composite denier and linear density greater than that of said braided structure.
10.
The prosthetic device according to claim 6, wherein said wrap is externally attached to said structure by an adhesive.
11.
The prosthetic device according to claim 6, wherein said wrap is incorporated into a layer of said braided structure.
12.
The prosthetic device according to claim 11, wherein said wrap is incorporated into an outer surface layer of said structure and forms a helical path therein
