Some patients lack the strength and dexterity to operate such pumps, and they are not anatomically comfortable when placed in incontinent females. Replacing manual pumps with electric pumps solves these problems. This study’s objective was to design a system to inflate penile cylinders from a nonferrous, reservoir-submerged package containing electronics, motor, pump and valves to replace the manual pump. The package is transdermally powered and controlled from a TV remote like controller. A Physician’s App programs the controller. Submerging the package in the reservoir provides heat transfer and allows abdominal implanting of only one part. Initial system requirements include pumping 60ml of normal saline at 25 psi in 45 seconds; MRI and SAR safety; minimum surgical impact, 2-inches separation between controller and implant; treat any and all of the above conditions; and no internal energy storage. METHODS: A survey of existing technology was conducted; innovative nonferrous motor and pump designs were considered; a baseline was selected; pump and motor performance was modeled; the motor stator was wound and tested; and a prototype transdermal power source, ferrous dc motor, and screw pump inflating penile cylinders was built and tested using commercially available parts. RESULTS: Modeling shows that the baseline system meets requirements. An added piezoelectric valve manifold prevents pump backflow and provides multi-implant inflation with one pump. The prototype system inflated the penile cylinders in 23-seconds using 3.6 watts source power with a 1-inch airgap between source and receiver. CONCLUSIONS: A nonferrous pump in reservoir system is feasible. Implantation of this transdermally powered pump in reservoir system can simultaneously treat three conditions in one patient while eliminating the need for manual pumps.
