초록

The reinforced tubular graft structure is particularly adapted for cardiovascular use and is made of collagenous tissue with a reinforcing fibrous structure surrounding the lumen. The fibrous structure comprises a coiled monofilament which can have a textured surface defined by randomly disposed strands of polymer on the outer surface of the monofilament. The coil can be embedded within the collagen or positioned about the collagen to form the graft structure.

대표
청구항

A method of forming a reinforced cardiovascular graft comprising the steps of: extending a segment of a monofilament between the chucks of a lathe; rotating the lathe chucks to rotate the monofilament; spraying the rotating monofilament with a continuous fluid polymer strand in a predetermined manner to form a fibrous layer that provides a textured surface to the monofilament; winding the textured surface monofilament around a mandrel to form a coil with predetermined pitch and inner diameter; placing the coil around a silicone rubber rod; inserting the ...
