Patent ID: 7833263

Claim:
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 first flowable reinforcing material applied to one of said outer or inner tube structures such that, subsequent to said application, said first reinforcing material rigidifies and has a configuration of an elongate rib having a serpentine configuration; a second flowable reinforcing material applied to the other of said outer or inner tube structures such that subsequent to said application, said second reinforcing material rigidifies and has a configuration of an elongate rib having a saw-tooth configuration; a filament material stitched to at least one of said reinforcing materials and to said outer or inner tube structure for securing the at least one of said reinforcing materials thereto such that the at least one of said reinforcing materials extends through a limited section of a circumference of said outer or inner tube structure wherein the at least one of said reinforcing materials has opposite ends between which a circumferential portion of said outer or inner tube structure is located; and a bonding material having a first state and a second state, in said first state said bonding material comprises a plurality of filaments woven through said outer tube structure, wherein in said first state, said inner tube structure is moveable relative to said outer tube structure; in said second state, said bonding material securingly bonds said outer tube structure to said inner tube structure.
