Artificial urinary sphincter and penile prosthesis using a shape memoryalloy. The artificial sphincter is constructed of Nitinol wite or plate core, Ni-Cr heating wire, and silicone-rubber. The erectile penile prosthesis consists of a pair of silicone rubber cylinder which are both implanted into the corpora cavernosa to achieve penile erection. Each silicone cylinder has a shape memory alloy wire core coiled with heating wire. Transformation speed was regulated by electric power and the force of transformation was controlled by the contents of the shape memory alloy. The results of animal experiments revealed that the bladder neck was occluded perfectly in the closing phase and urine was voided from the bladder durring the opening phase.

应用形状记忆合金的人造尿道括约肌和阴茎假体。人工括约肌由镍钛合金芯或板芯、镍铬电热丝和硅橡胶制成。阴茎勃起假体由一对硅橡胶圆柱体组成，均植入阴茎海绵体内实现阴茎勃起。每个硅胶圆筒都有一个形状记忆合金线芯，缠绕着加热丝。相变速度由电功率调节，相变力由形状记忆合金的含量控制。动物实验结果表明，在闭合期膀胱颈完全闭合，在开放期尿液从膀胱排出。
