Abstract
An implantable vascular graft includes an outer tube structure formed of a textile material, and an inner tube structure formed of a non-textile material. The inner tube structure is within the outer tube structure in coaxial relation therewith. One or both of the outer and inner tube structures have deformable reinforced portions incorporated therein. The deformable reinforced portions provide for conformance of the associated one or both of the outer and inner tube structures to a vessel of a patient. An implantable laminate prosthesis includes a first layer structure formed of textile material, and a second layer structure formed of non-textile material. The first and second layer structures are secured together in laminating relation. The first or second layer structure has a reinforced portion.
Claims73
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material;
- an inner tube structure formed of a non-textile material, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith, said outer or inner tube structure having a deformable reinforced portion incorporated into said structure which provides for conformance thereof to a vessel of a patient.
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material, said textile being weaved, knitted or braided;
- and
- an inner tube structure formed of a non-textile material, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith, said outer or inner tube structure having a reinforced portion incorporated into at least one of said structures.
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material and having an outer surface;
- and
- an inner tube structure formed of a non-textile material and having an inner surface, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith, said outer or inner surface having a reinforced portion.
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material, said outer tube structure having an outer surface;
- an inner tube structure formed of a non-textile material and having an inner surface, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith;
- a channel extending from said outer or inner surface, said channel having a pair of sides which are generally perpendicular to the adjoining one of said outer or inner surfaces;
- and
- a reinforcing material located within and secured to said channel.
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material;
- an inner tube structure formed of a non-textile material, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith;
- a flowable reinforcing material applied to said outer or inner tube structure such that, subsequent to said application, said reinforcing material rigidifies;
- and
- a filament material stitched to said reinforcing material and to said outer or inner tube structure for securing said reinforcing material thereto.
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material;
- and
- an inner tube structure formed of a non-textile material, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith, at least a portion of said outer or inner tube structure being crimped.
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material;
- an inner tube structure formed of a non-textile material, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith;
- and
- a highly absorbent material secured to said outer or inner tube structure.
An implantable vascular graft comprising:
- an outer tube structure formed of a textile material;
- an inner tube structure formed of a non-textile material, said inner tube structure being secured to said outer tube structure such that said inner tube structure is within said outer tube structure in coaxial relation therewith;
- and
- a stiffening rib formed of a PTFE or adhesive material, said stiffening rib being secured to said outer or inner tube structure.
An implantable laminate prosthesis comprising:
- a first layer structure formed of a textile material;
- and
- a second layer structure formed of a non-textile material, said first and second layer structures being secured together in laminating relation to one another, said first or second layer structure having a reinforced portion.
