A method for producing a prothesis for implanting in a human patient so as to form a bypass or arteries such as aorto-coronary bypass, said prothesis comprising a living vein which is taken from the patient and a multi-perforated flexible sheath surrounding the vein, said method comprising taking a vein from the patient, surrounding said vein with a multi-perforated flexible sheath, said sheath having an inside diameter which is so chosen that, after implantation, said vein is constrained by said sheath so that its outside diameter is maintained by said sheath at a value less than the maximum possible diameter of said vein and that its inside diameter is substantially or very close to the receiver artery diameter.
