ABSTRACT:
A pressure relief valve system for a prosthetic penile implant device where the penile implant device basically includes bladder means, a reservoir, and a pump and valve assembly. The bladder means is implanted in the penis while the reservoir, and the pump and valve assembly are implanted at a remote location thereto. The pump and valve assembly provide means for pumping water from the reservoir into the bladders to obtain a simulated erection and for pumping water from the bladders to the reservoir to obtain a flaccid penis. The pressure relief valve system of the instant invention is used in combination with the pump and valve assembly to prevent excessive pressure from developing within the bladder means so as to cause injury. The pressure relief valve system comprises a primary valve and a secondary valve. The primary valve enables water to pass from the pump means to the reservoir, bypassing the bladder means whenever the water pressure adjacent the pump means exceeds a predetermined threshold amount, while the secondary valve enables water to pass from the bladder means to the reservoir whenever the water pressure adjacent the bladder means exceeds a second, generally higher amount.
