Patent number: 8276591Abstract: A method of preventing inadvertent inflation of an implantable prosthetic includes biasing a valve assembly such that an outlet is substantially closed and using inadvertent pressure increases from the inlet to supplement the biasing of the valve assembly. It may further include the step of preventing fluid flow through the outlet by selectively varying fluid pressure within a bypass passageway having a first end which is in fluid communication with an inlet and a second end which is in fluid communication with a chamber. And, may also additionally include the step of displacing a flexible abutting wall disposed between the chamber and the valve assembly so that the abutting wall is caused to contact the valve assembly and urge the valve assembly into a closed position when the fluid pressure within the chamber exceeds a predetermined amount.Type: GrantFiled: October 14, 2008Date of Patent: October 2, 2012Assignee: AMS Research CorporationInventors: Gregory J. Henkel, Larry E. Waldack, Charles C. Kuyava, Randy L. Morningstar, John G. Almli

Patent number: 8109870Abstract: An inflatable penile prosthesis includes an implantable pump having a bypass valve. The bypass valve includes a cavity having a valve seat at a port, a poppet and a spring. The poppet includes a valve member and a stem extending from the valve member. In operation, the poppet includes a sealing position, where the valve member seals the port through contact with the valve seat, and a deflating position, where the valve member is displaced from the valve seat. The spring is configured to bias the valve member toward the valve seat, wherein the spring engages a portion of the stem while the poppet is in the deflating position.Type: GrantFiled: November 12, 2007Date of Patent: February 7, 2012Assignee: AMS Research CorporationInventors: Charles C.

Patent number: 7438682Abstract: A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the patient. The pump assembly has an actuating bar with ribs to enhance the spring force applied to a flow valve, a support structure to support and appropriately position the actuating bar, and a check valve made of metal with a segment covered with a plastic material. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the cylinders 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.Type: GrantFiled: April 8, 2004Date of Patent: October 21, 2008Assignee: AMS Research CorporationInventors: Gregory J.
