Patent Images
1. A reinforced graft assembly, comprising:
- (a) a compliant graft component, said graft component having an inner surface and an outer surface, said graft component being made from synthetic, biologic, or biosynthetic materials; and
(b) a sleeve component, said sleeve component being made from synthetic, biologic, or biosynthetic materials, said sleeve component being cylindrically shaped and having an inner diameter suitably sized so the sleeve component may be fitted over the graft component, whereby said sleeve component provides compliant reinforcement to said graft component, said sleeve component including layers which provide said reinforcement to said graft component, said layers including an internal layer, an intermediate layer, and an external layer, and wherein said intermediate layer includes fibers in the form of a ribbon or filament having a diameter in the range of 300 to 3,000 microns.

Abstract
A reinforced graft assembly made from a vascular graft component and a reinforcing sleeve component. The reinforcing sleeve component may include one or more layers. The diameter of the inner surface of the most internal layer of the reinforcing sleeve component is approximately equal to or larger than the diameter of the vascular graft component thereby allowing the former to be fitted over the latter. The compliance of the sleeve component is adjustable depending on the application needs, for example, by varying the angle at which the fibers used to form the sleeve component are laid down and by the method used to join the two components.
