Abstract
The present invention provides a soft tissue prosthesis which is formed from a three-dimensional braided structure. The three-dimensional braided structure preferably may be made in the form of a solid three-dimensional braid, a three-dimensional braid having at least one interlocking yarn coupling contiguous layers or in the form of a plurality of two-dimensional braided layers adhesively laminated, separately sewn or otherwise connected together to form the three-dimensional braided prosthesis.
Claims15
An implantable tubular prosthesis, comprising:
- a continuous elongate hollow three-dimensional braided structure having a plurality of layers in which at least one yarn of each layer extends into an adjacent layer to interlock said layers, said structure having an intraluminal fluid contacting surface and an outer tissue contacting surface along its length thereof;
- and
- wherein at least one of said layers includes a fusible component which upon melting integrally bonds said layers for enhanced resistance to ravelling and fraying.
An implantable tubular prosthesis, comprising:
- a three-dimensional braided structure having a plurality of layers in which at least one yarn of each layer extends into an adjacent layer to interlock said layers, said structure having an intraluminal surface and an outer surface;
- and
- wherein both said intraluminal surface and said outer surface include pores, and wherein said pores on said outer surface have an average pore size greater than said pores on said intraluminal surface, and wherein the average pore size changes progressively from said outer surface to said intraluminal surface.
