ABSTRACT:
An implantable infusion system has a neutral pressure medication supply container for liquid medication to be delivered to the patient, the supply container being devised so that its volume changes according to the amount of medication it contains, and a pump for pumping medication from the supply container, via a catheter, to the patient's body. The supply container and the pump are arranged inside an enclosure to which the catheter is connectable at the output of the pump. A closed space, at least partly contained inside the enclosure, in which the supply container is arranged, and in which essentially atmospheric pressure prevails, is arranged to change its volume to a corresponding degree when the volume of the supply container changes, so that the pressure is kept essentially unchanged.
