First Claim
1. An arteriovenous bypass grafting procedure, which comprises fitting an elongate device around an external surface of a vessel to be grafted, wherein the device is arcuate in cross-section and self-supporting, and wherein the device comprises inner and outer layers that are maintained in contact by their natural elasticity or by bonding, wherein the outer layer is more rigid than the inner layer such that it provides a structural framework for the device, wherein the inner layer stimulates neovascularisation and degrades faster than the outer layer, and wherein the device is fitted around the external surface of the vessel such that there is a space between the device and the vessel.
