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 following the heart's contractions. The implantable device comprising a first pump device adapted to assist the pump function of the heart. The pump device comprises 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. The 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 wherein 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, following the heart's contractions, for improving the pump function of the heart, when said device is implanted. The implantable device further comprises a sensor sensing muscle contractions of the heart.
