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.
Claims20
Total or partial ureteral prosthesis for an organism characterized in that it comprises a generally tubular device with pump effect having an upstream end and a vesical end, compatible with urine and with the organism, made from flexible plastic material which is compatible with the surrounding tissues, which device presents a permanent set distortion on at least one point of its course which modifies the aforesaid course, and is provided with an anti-reflux valve at least on its vesical end, which valve cooperates with the aforesaid set distortion to vary the volume of the aforesaid prosthesis under the action of the physiological movements of the organism, thus creating the desired pump effect.
