Abstract

Urinary incontinence is a prevalent urological problem that can cause major negative impacts on patient"s quality of life and their relatives. The use of artifical urinaty sphincter (AUS) is the most effective way on therapy of some neurological defect, low active sphincter and after prostatectomy. The most popular A US is AMS 800, which is expensive and has limited usage in Iran. In this article the designation and fabrication of the experimental AUS made up of MEMORY SHAPE ALLOY (MSA) were introduced. This prosthesis can open and close the duct under the pressure equal to the human urinary bladder via the effect of electrical cwrent. Because this prosthesis ultimately used for implantation on animal study and ultimately human, the activator outside the body provides electrical current for receiver and amplifier inside the body through magnetic filed cuppling method. The mechanical part of prosthesis is cylindrical sphincter, which open and close the duct (similar to human urinary duct) following change in the length of MSA wire. Results indicated that by turning on the instrument 50 mm away from receiver the magnetic field current is produced in the receiver and using 3W amplifier electrical current produced which is able to warm the MSA wire and shorten its length The force produced following shorten the wire length will overcome the sphincter spring source (that already close the sphincter) and open sphincter. Followed by turning off the activator, the MSA wire became cool and spring force get the sphincrer to it"s original shape. In conclusion, the electromechanical artifical urethral sphincter designed in this study as a portable prosthesis working by 12V small battery may be cnnsidered as new model of artificial urethral sphincter for experimental animal study.
