An infusion chamber to be implanted through an incision in the skin e.g. in the upper thoracic area, comprises a reservoir (15) for medication with an access zone (26) at the top for filling and an infusion duct (27) extending from it, and outer housing (17) with a triangular base and a side wall (19) that tapers towards the apex of the triangle. An infusion chamber to be implanted through an incision in the skin e.g. in the upper thoracic area, comprises a reservoir (15) for medication with an access zone (26) at the top for filling and an infusion duct (27) extending from it, and outer housing (17) with a triangular base and a side wall (19) that tapers towards the apex of the triangle. The portion of the infusion duct closest to the reservoir is enclosed within the housing, and its outer end lies parallel to the base of the triangle after turning through an angle of 100 - 150 degrees.
