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 valve body, a pump bulb, and a deflation mode actuator. The valve body includes a bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the deflation mode actuator. The bi-directional valve in the inflation position is configured to open a fluid passageway in the valve body to transfer fluid from the pump bulb to the inflatable member. The bi-directional valve in the deflation position is configured to open a fluid passageway in the valve body to transfer fluid from the inflatable member to the fluid reservoir that bypasses the pump bulb.

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 valve body, a pump bulb, a first deflation mode actuator and a second deflation mode actuator, the valve body including a bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the deflation mode actuator, the bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the first deflation mode actuator, the bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the second deflation mode actuator
the bi-directional valve in the inflation position configured to open a fluid passageway in the valve body to transfer fluid from the pump bulb to the inflatable member,
the bi-directional valve in the deflation position configured to open a fluid passageway in the valve body to transfer fluid from the inflatable member to the fluid reservoir that bypasses the pump bulb.

2. The inflatable penile prosthesis of claim 1 , wherein the bi-directional valve includes a control valve ball configured to move between the inflation position and the deflation position.

3. The inflatable penile prosthesis of claim 2 , wherein the bi-directional valve includes at least one pusher member operatively coupled to the first deflation mode actuator, the at least one pusher member configured to cause the control valve ball to move to the deflation position.

4. The inflatable penile prosthesis of claim 3 , wherein the at least one pusher member includes a first pusher member operatively coupled to the first deflation button, and a second pusher member operatively coupled to the second deflation button.

5. The inflatable penile prosthesis of claim 4 , wherein actuation of either the first deflation button or the second deflation button causes the control valve ball to move to the deflation position.

6. The inflatable penile prosthesis of claim 1 , wherein the first deflation mode actuator includes a feedback component configured to provide at least one of tactile or auditory feedback in response to the activation of the first deflation mode actuator.

7. The inflatable penile prosthesis of claim 1 , wherein the valve body includes a first surface and a second surface opposite the first surface, and the deflation mode actuator includes a first deflation button extending from the first surface, and a second deflation button extending from the second surface.

8. The inflatable penile prosthesis of claim 1 , wherein the pump assembly includes a plurality of fluid transfer ports that extend from the valve body, the plurality of fluid transfer ports including a reservoir fluid port, a first cylinder fluid port, and a second cylinder fluid port.

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

10. The inflatable penile prosthesis of claim 1 , wherein the valve body includes an inflation valve fluidly coupled to the pump bulb.

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 bi-directional valve is in the deflation position.

12. A pump assembly for an inflatable penile prosthesis comprising:
a valve body including a bi-directional valve;
a plurality of fluid transfer ports extending from the valve body, the plurality of fluid transfer ports including a reservoir fluid port and at least one cylinder fluid port;
a pump bulb extending from the valve body; and
a first deflation mode actuator moveably coupled to the valve body,
a second deflation mode actuator movably coupled to the valve body,
the bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the first deflation mode actuator,
the bi-directional valve in the inflation position configured to open a fluid passageway from the pump bulb to the at least one cylinder fluid port,
the bi-directional valve in the deflation position configured to open a fluid passageway from the reservoir fluid port to the at least one cylinder fluid port that bypasses the pump bulb.

13. The pump assembly of claim 12 , wherein the first deflation mode actuator includes a deflation button and a feedback component configured to provide at least one of tactile or auditory feedback in response to the deflation button being pressed by a user.

14. The pump assembly of claim 12 , wherein the valve body includes a first surface and a second surface opposite the first surface, and the first deflation mode actuator includes a first deflation button extending from the first surface, and a second deflation button extending from the second surface.

15. The pump assembly of claim 12 , wherein the valve body includes a refill valve disposed in a fluid passageway between the reservoir fluid port and the pump bulb, the refill valve being aligned along an axis that extends along a longitudinal axis of the reservoir fluid port, the refill valve configured to transfer fluid from the fluid reservoir to the pump bulb when the bi-directional valve is in the inflation position.

16. The pump assembly of claim 12 , wherein the bi-directional valve includes a control valve ball and at least one pusher member operatively coupled to the first deflation mode actuator, the at least one pusher member configured to cause the control valve ball to move to the deflation position.

17. The pump assembly of claim 16 , wherein the first deflation mode actuator includes a first deflation button extending from a first surface of the valve body, and a second deflation button extending from a second surface of the valve body, the at least one pusher member includes a first pusher member operatively coupled to the first deflation button, and a second pusher member operatively coupled to the second deflation button.

18. The pump assembly of claim 12 , 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 bi-directional valve is in the deflation position.

19. 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; and
transferring the fluid from the pump bulb to the inflatable member via an inflation valve and a bi-directional valve;

moving the bi-directional valve to a deflation position in response to activation of a first deflation mode actuator or a second deflation mode actuator; and
transferring the fluid from the inflatable member to the fluid reservoir via the bi-directional valve such that the fluid is not transferred through the pump bulb.

20. The method of claim 19 , 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 bi-directi
