Abstract

According to an aspect, an inflatable penile prosthesis includes a fluid reservoir, an inflatable member, and a pump assembly. The pump assembly includes a pump bulb, a valve body, a push valve movably coupled to the valve body, a first fluid port, and a second fluid port. The push valve includes a movable valve element configured to move between an inflation position and a deflation position within a bore of the valve body. The movable valve element in the inflation position defines a fluid passageway through the bore to transfer fluid from the pump bulb to the second fluid port. The movable valve element, when moved to the deflation position, is configured to change the fluid passageway through the bore to transfer fluid from the second fluid port to the first fluid port such that the pump bulb is bypassed.

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 push valve movably coupled to 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 push valve including a movable valve element configured to move between an inflation position and a deflation position within a bore of the valve body, the pump assembly including an anti-auto inflate valve disposed fluidically between the bore and the fluid reservoir,
the movable valve element in the inflation position defining a fluid passageway through the bore to transfer fluid from the pump bulb to the second fluid port, the movable valve element, when moved to the deflation position, configured to change the fluid passageway through the bore to transfer fluid from the second fluid port to the first fluid port such that the pump bulb is bypassed.

2. The inflatable penile prosthesis of claim 1 , wherein the push valve includes a biasing member that biases the movable valve element to the inflation position.

3. The inflatable penile prosthesis of claim 1 , wherein the push valve includes a poppet having a ring member.

4. The inflatable penile prosthesis of claim 1 , wherein the movable valve element is configured to move to the deflation position in a linear direction based on a single instantaneous push of the movable valve element by a user.

5. The inflatable penile prosthesis of claim 1 , wherein the pump assembly includes a button component that encloses a portion of the movable valve element when the movable valve element is in the inflation position.

6. The inflatable penile prosthesis of claim 5 , wherein the pump assembly includes a feedback component disposed between the button component and the movable valve element, the feedback component configured to provide at least one of tactile or auditory feedback in response to the movable valve element being moved to the deflation position.

7. The inflatable penile prosthesis of claim 1 , wherein a portion of the movable valve element extends outside the valve body when the movable valve element is in the inflation position, the portion of the movable valve element being disposed inside the valve body when the movable valve element is in the deflation position.

8. The inflatable penile prosthesis of claim 1 , wherein the valve body includes a refill valve aligned with the first fluid port, the refill valve configured to transfer fluid from the fluid reservoir to the pump bulb when the movable valve element is in the inflation position.

9. The inflatable penile prosthesis of claim 1 , wherein the valve body includes an inflation valve disposed in a fluid passageway between the pump bulb and the bore.

10. The inflatable penile prosthesis of claim 1 , wherein the movable valve element includes a first movable member and a second movable member.

11. The inflatable penile prosthesis of claim 1 , wherein the valve body includes a refill valve, and an inflation valve, wherein the refill valve and the inflation valve are not used when the movable valve element is in the deflation position.

12. A pump assembly for an inflatable penile prosthesis comprising:
a push valve movably coupled to a valve body, the push valve including a movable valve element configured to move between an inflation position and a deflation position within a bore of the valve body;
a plurality of fluid transfer ports including a first fluid port configured to be fluidly coupled to a fluid reservoir, and a second fluid port configured to be fluidly coupled to an inflatable member; and
an anti-auto inflate valve disposed fluidically between the bore and the fluid reservoir,
the movable valve element in the inflation position defining a fluid passageway through the bore to transfer fluid from a pump bulb to the second fluid port, the movable valve element, when moved to the deflation position, configured to change the fluid passageway through the bore to transfer fluid from the second fluid port to the first fluid port such that the pump bulb is bypassed.

13. The pump assembly of claim 12 , wherein the movable valve element includes a cylindrical unitary body having at least two sections with different diameters.

14. The pump assembly of claim 12 , wherein the first fluid port includes a first tubular member, and the second fluid port includes a second tubular member and a third tubular member, the second tubular member configured to be fluidly coupled to a first cylinder member of the inflatable member, the third tubular member configured to be fluidly coupled to a second cylinder member of the inflatable member.

15. The pump assembly of claim 12 , further comprising:
a refill valve disposed within the valve body at a location that is aligned with a longitudinal axis of the first fluid port; and
an inflation valve disposed in a fluid passageway between the bore and the pump bulb.

16. The pump assembly of claim 12 , wherein the movable valve element is configured to move from the inflation position to the deflation position along an axis, the axis being substantially orthogonal to the longitudinal axis of the first fluid port.

17. The pump assembly of claim 12 , wherein a portion of the movable valve element extends outside the valve body when the movable valve element is in the inflation position, the pump assembly further comprising:
a button component that encloses the portion of the movable valve element; and
a feedback component disposed between the button component and an end portion of the movable valve element, the feedback component configured to provide at least one of tactile or auditory feedback in response to the movable valve element being moved to the deflation position.

18. A method for controlling a direction of fluid through a pump assembly of an inflatable penile prosthesis, the method comprising:
transferring, by a pump assembly, fluid from a fluid reservoir to an inflatable member, including:
transferring the fluid from the fluid reservoir to a pump bulb via a refill valve;
transferring the fluid from the pump bulb to the inflatable member via an inflation valve and a push valve having a movable valve element;

pushing the movable valve element disposed within a bore along an axis to a deflation position to change a fluid passageway through a valve body of the pump assembly; and
transferring the fluid from the inflatable member to the fluid reservoir via the push valve such that the fluid is transferred through the bore and an anti-auto inflate valve disposed fluidically between the bore and the fluid reservoir and such that the fluid is not transferred through the pump bulb.

19. The method of claim 18 , wherein the refill valve and the inflation valve are not used to transfer the fluid from the inflation member to the fluid reservoir when the movable valve element is in the deflation position.

20. The inflatable penile prosthesis of claim 1 , wherein the anti-auto inflate valve includes a check ball and a biasing member.
