Abstract

An implantable inflatable device includes a fluid reservoir defining a cavity, an inflatable member, a pump assembly configured to transfer fluid from the fluid reservoir to the inflatable member, and a filter member. The fluid being configured to pass through the filter member when the pump assembly transfers the fluid from the fluid reservoir to the inflatable member.

Claims (30)

1 . An implantable inflatable device, comprising:

a fluid reservoir defining a cavity;

an inflatable member;

a pump assembly configured to transfer fluid from the fluid reservoir to the inflatable member; and

a filter member, the fluid being configured to pass through the filter member when the pump assembly transfers the fluid between the fluid reservoir to the inflatable member, the filter member defining a first opening, a second opening, a third opening, and a fluid pathway fluidically coupling the first opening, the second opening, and the third opening.

2 . The inflatable device of claim 1 , wherein the pump assembly includes a pump, the filter member is operatively coupled between the pump and the fluid reservoir.

3 . The inflatable device of claim 1 , wherein the pump assembly includes a pump, the filter member is operatively coupled between the pump and the inflatable member.

4 . The inflatable device of claim 1 , further comprising:

a connection member extending between the fluid reservoir and the pump assembly to operatively couple the fluid reservoir to the pump assembly, the filter member being disposed within the connection member.

5 . The inflatable device of claim 1 , further comprising:

a connection member extending between the inflatable member and the pump assembly to operatively couple the inflatable member to the pump assembly, the filter member being disposed within the connection member.

6 . The inflatable device of claim 1 , wherein the filter member is a self-cleaning filter.

7 . The inflatable device of claim 1 , wherein the filter member defines a fluid pathway, the fluid pathway having a tapered shape.

8 . The inflatable device of claim 1 , wherein the first opening has a size, the second opening has a size, the third opening has a size, the size of the first opening being different than the size of the second opening and being different than the size of the third opening.

9 . The inflatable device of claim 1 , wherein the first opening is disposed on the first side of the filter, the second opening is disposed on the second side of the filter, the third opening is disposed on the second side of the filter.

10 . The inflatable device of claim 1 , wherein the filter member is a lattice filter.

11 . The inflatable device of claim 1 , wherein the filter member defines a fluid pathway, the fluid pathway having a torturous path.

12 . The inflatable device of claim 1 , wherein the filter member is disposed within the pump assembly.

13 . The inflatable device of claim 1 , wherein the pump assembly includes a housing, the housing having anchoring members.

14 . An implantable inflatable device, comprising:

a fluid reservoir defining a cavity;

an inflatable member;

a pump assembly configured to transfer fluid from the fluid reservoir to the inflatable member;

a first connection member extending between the fluid reservoir and the pump assembly;

a second connection member extending between the inflatable member and the pump assembly; and

a filter member, the filter member defines a first opening, a second opening, and a lumen extending between the first opening and the second opening, the first opening having a size, the second opening having a size, the size of the first opening being larger than the size of the second opening.

15 . The inflatable device of claim 14 , wherein the filter member is disposed within the first connection member.

16 . The inflatable device of claim 14 , wherein the filter member is disposed within the second connection member.

17 . The inflatable device of claim 14 , wherein the filter member is a self-cleaning filter.

18 . The inflatable device of claim 14 , wherein the filter member defines a fluid pathway, the fluid pathway having a tapered shape.
