ABSTRACT:
A ureteral prosthesis comprises a generally tubular member (9) of a urine-resistant and physiologically acceptable flexible material. The tubular member (9) has at least one permanent distortion (7) along its length, and has at least one anti-reflux valve (5) at its downstream end. The permanent distortion (7) is formed so that it co-operates with valve (5) in use of the prosthesis so as to vary the internal volume of the aforesaid prosthesis under the influence of physiological movement of a body part of a patient in which the prosthesis is implanted, which movement results in deformation of the flexible tubular member (9), whereby a pump-action is obtained in the prosthesis.
