1. A bypass valve of an implantable pump of an inflatable penile prosthesis comprising:
- a bypass cavity having a valve seat at a port;
a poppet comprising a valve member and a stem extending from the valve member, the poppet including a sealing position, in which the valve member seals the port through contact with the valve seat and a deflating position, in which the valve member is displaced from the valve seat; and
a spring 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.

Abstract
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.

14. A method of reducing noise produced by a bypass valve of an implantable pump of an inflatable penile prosthesis during deflation of cylinders of the penile prosthesis, the bypass valve comprising a bypass cavity having a valve seat at a port, a poppet comprising a valve member and a stem extending from the valve member, and a spring, the method comprising steps of:
-
biasing the poppet with the spring into a sealing position, in which the valve member seals the port through contact with the valve seat; introducing a flow of fluid to the port; moving the poppet from the sealing position to a deflating position in response to the flow of fluid, wherein the valve member is displaced from the valve seat and the flow of fluid travels through the bypass cavity; and inhibiting vibratory movement of the poppet relative to the valve seat through frictional resistance between the stem and the spring.

15. A bypass valve of an implantable pump of an inflatable penile prosthesis:
-
a bypass cavity having a valve seat at a port; a poppet comprising a valve member, the poppet including a sealing position in which the valve member seals the port through contact with the valve seat and a deflating position, in which the valve member is displaced from the valve seat; and a spring biasing the valve member toward the valve seat; wherein the frequency of the vibrating spring and poppet system is less than 2500 Hz. - View Dependent Claims (16, 17, 18, 19, 20, 21)
