Abstract: A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the user. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the pump assembly from unintended fluid flow. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This is accomplished by incorporating appropriate mechanisms within the pump itself.

Abstract: Method and apparatus for applying a thermal conductive medium (TCM) to the inside of a disposable sheath. A uniform amount of TCM is applied in an automated manner to the conductive portion of a disposable sheath to increase conductivity. Application is by way of a rotating tip having a plurality of nozzles through which TCM is pumped under control of a timing circuit. The duration of TCM application and the rotation of the tip is carefully controlled to insure uniform application of a precise amount of TCM. TCM application is avoided at portions of the sheath where thermal conductivity is not desired and at the tip of the sheath which will be coated by TCM as a result of probe insertion into the sheath. By automating the TCM application process, TCM can be applied in precise amounts and in a uniform manner without accidentally coating areas of the sheath where TCM is not desired. In addition the process can be conducted in far less time than is required to manually apply TCM.
