| titleOfInvention | Coated vascular prosthesis and methods of manufacture and use. |
| abstract | A method for forming a kink resistant, blood impermeable graft comprises the steps of: providing a crimped substrate of polymer fabric; coating the outer surface of the substrate with a first solution comprising a first polymer and a particulate in a first solvent; allowing the first solution to dry, thereby forming a first coat on the substrate; coating the first coat with a second solution comprising a second polymer in a second solvent; and immersing the coated substrate in a third solvent to precipitate the second polymer from solution, thereby forming a porous second coat. The third solvent also dissolves the salt in the first coat to form pores in the first coat. The first and second polymer solutions do not penetrate to the interior surface of the substrate of the graft. Vascular prostheses made by this method are blood impermeable and kink resistant and are particularly useful as outflow cannulas for ventricular assist devices. |
