Abstract

The present invention relates to an implantable device for improving the pump function of the heart of a human patient by applying an external force on the heart muscle. The implantable device comprises at least one implantable pump device comprising: A fluid, A first reservoir having a first volume and at least one movable wall portion, for varying said first volume, and A second reservoir being in fluid connection with said first reservoir. Wherein said implantable pump device is adapted to allow free flow of fluid between said first reservoir and said second reservoir, and wherein said first reservoir, said second reservoir and said fluid connection forms a fully implantable closed pump device, and wherein said fully implantable closed pump device is adapted to transfer force from said first reservoir to said second reservoir.

Claims

1. An implantable device for improving the pump function of the heart of a human patient by applying an external force on a first position of the heart muscle, said implantable device comprising a first pump device adapted to assist the pump function of the heart, said pump device comprising:

a first reservoir having a first volume and adapted to varying said first volume,

a second reservoir having a second volume and adapted to varying said second volume,

a fluid connection adapted to fluidly connect said first reservoir with said second reservoir, such that fluid can flow between said first reservoir and said second reservoir, wherein

said first reservoir, said second reservoir and said fluid connection forms a fully implantable pump device adapted to maintain a fluid in a closed system, when in operation, and wherein

said fully implantable pump device is adapted to transfer force by transferring fluid from said first reservoir to said second reservoir to direct or indirect applying an external force on the first position of the heart muscle for improving the pump function of the heart, when said device is implanted.

2. The implantable device according to claim 1, wherein said implantable device further comprises a second or more implantable pump device(s) for applying force on a second or more position(s) on the heart muscle comprising:

at least one additional first reservoir having a first volume and adapted to varying said first volume,

at least one additional second reservoir having a second volume and adapted to varying said second volume,

a fluid connection adapted to fluidly connect said first reservoir with said second reservoir, such that fluid can flow between said first reservoir and said second reservoir, wherein

said first reservoir, second reservoir and said fluid connection forms a fully implantable pump device adapted to maintain a fluid in a closed system, when in operation, and wherein

said fully implantable pump device is adapted to transfer force by transferring fluid from said at least one first reservoir to said at least one second reservoir to direct or indirect applying an external force on the at least second position of the heart muscle for improving the pump function of the heart, and when said device is implanted.

3. The implantable device according to claim 1, wherein said pump device comprising:

one or more additional second reservoir(s) being in fluid connection with said first reservoir,

at least one valve adapted to have different valve positions, adapted to be placed in the fluid connection between said first reservoir and said second and said one or more additional second reservoir(s),

wherein said valve is adapted to connect said first reservoir with at least one of the second reservoir and said one or more additional second reservoir(s), wherein

said reservoirs and said fluid connections forms a fully implantable pump device adapted to maintain a fluid in a closed system, when in operation, and wherein

said pump device is adapted to transfer force by transferring fluid from said first reservoir to one or more additional second reservoirs to direct or indirect applying an external force on the second or more positions of the heart muscle for improving the pump function of the heart, depending on the position of the valve, when said device is implanted.

4. The implantable device according to claim 1, wherein said pump device comprising at least one of:

at least one movable piston, for varying said first volume or second volume, and

at least one movable wall of said first and second reservoir for varying said first volume or second volume.
