Abstract

According to an aspect, an inflatable penile prosthesis includes a fluid reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to transfer the fluid between the fluid reservoir and the inflatable member. The pump assembly includes a pump bulb, a valve body, a valve disposed within the valve body, a first fluid port configured to be fluidly coupled to the fluid reservoir, and a second fluid port configured to be fluidly coupled to the inflatable member. The valve is configured to move between an inflation position and a deflation position. The valve includes a first member and second member, the first member being configured to move with respect to the second member.

First claim

What is claimed is:

1. An inflatable penile prosthesis comprising:
a fluid reservoir configured to hold fluid;
an inflatable member; and
a pump assembly configured to transfer the fluid between the fluid reservoir and the inflatable member, the pump assembly including a pump bulb, a valve body, a valve disposed within the valve body, a first fluid port configured to be fluidly coupled to the fluid reservoir, and a second fluid port configured to be fluidly coupled to the inflatable member, the valve being configured to move between an inflation position and a deflation position,
wherein the valve includes a first member and second member, the first member being configured to move with respect to the second member, the first member includes a first end portion and a second end portion opposite the first end portion, the first end portion of the first member having a non-planar surface, the second end portion of the first member defining a cavity, the second member having a surface that is configured to engage the non-planar surface of the first end portion of the first member.

2. The inflatable penile prosthesis of claim 1 , wherein the valve includes a third member, the third member of the valve is fixedly coupled within the valve body.

3. The inflatable penile prosthesis of claim 1 , wherein the valve includes a third member, the third member of the valve includes a projection, the cavity of the second end portion of the first member being configured to receive at least a portion of the projection of the second member.

4. The inflatable penile prosthesis of claim 1 , wherein the valve includes a third member, the third member of the valve includes a projection, the cavity of the second end portion of the first member being configured to receive at least a portion of the projection of the third member, the third member being fixedly coupled within the valve body.

5. The inflatable penile prosthesis of claim 1 , further comprising a biasing member disposed adjacent the first member.

6. The inflatable penile prosthesis of claim 1 , further comprising a spring member disposed adjacent the first member.

7. The inflatable penile prosthesis of claim 1 , wherein the valve body includes a sealing ring, the first member of the valve includes a surface, the surface being configured to engage the sealing ring when the valve is in the deflation position.

8. The inflatable penile prosthesis of claim 1 , wherein the valve includes a third member, the first member of the valve includes a contact ring, the third member of the valve includes a projection having an outer surface, the contact ring being configured to engage the outer surface of the projection.

9. The inflatable penile prosthesis of claim 1 , wherein the valve includes a third member, the valve body includes a retainer member configured to engage the third member of the valve to help fixedly couple the third member of the valve to the valve body.

10. An inflatable penile prosthesis comprising:
a fluid reservoir configured to hold fluid;
an inflatable member; and
a pump assembly configured to transfer the fluid between the fluid reservoir and the inflatable member, the pump assembly including a pump bulb, a valve body, a valve disposed within the valve body, a first fluid port configured to be fluidly coupled to the fluid reservoir, and a second fluid port configured to be fluidly coupled to the inflatable member, the valve being configured to move between an inflation position and a deflation position,
wherein the valve includes a first member and second member, the first member being configured to move with respect to the second member, the first member includes a first end portion and a second end portion opposite the first end portion, the first end portion of the first member having a non-planar surface, the second end portion of the first member defining a cavity, the second member having a surface that is configured to engage the non-planar surface of the first end portion of the first member, the valve member includes a biasing member disposed between a portion of the valve body and the first member of the valve.

11. The inflatable penile prosthesis of claim 10 , wherein the biasing member is a spring.

12. The inflatable penile prosthesis of claim 10 , wherein the first member of the valve includes a convex surface that is configured to engage the non-planar surface of the second member of the valve.

13. The inflatable penile prosthesis of claim 10 , wherein the valve body includes a sealing ring, the first member of the valve includes a surface, the surface being configured to engage the sealing ring when the valve is in the deflation position.
