Claim:
1. A surgical method for implanting a pump device for improving the pump function of the heart of a human patient, by applying an external force on the heart muscle to assist in and help the pump function of the heart, the surgical method comprising the steps of: implanting a first reservoir having a first volume and adapted to varying said first volume, implanting a second reservoir having a second volume and adapted to varying said second volume, implanting 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, such that said first reservoir, said second reservoir and said fluid connection form a fully implantable pump device adapted to maintain a fluid in a closed system, when in operation, and said fully implantable pump device is adapted to transfer force by transferring fluid from said first reservoir to said second reservoir to directly or indirectly apply an external force on the first position of the heart muscle, and wherein said surgical method further comprises: implanting a sensor that, when implanted in the body, senses muscle contractions of the heart.
