Abstract: A special purpose modular receptacle comprises a generally rectangular housing having an opening which exposes a cavity within the housing. A plurality of electrical contacts are disposed within the cavity of the housing. Terminal ends of the contacts electrically connect to corresponding contacts on a standard modular connector or a modified modular connector inserted into the cavity. The contacts are exposed at a lower rear portion of the housing allowing connection between the contacts and a printed circuit board. Attachment means allow physical and electrical connection of the housing to a printed circuit board. A guiding means may be present as a modular connector insertion aid.

Abstract: A special purpose modular connector comprising a generally rectangular housing having a central body portion and two extending side arm portions. A plurality of electrical contacts are disposed within the body and arm portions. Slots at a front end of each portion of the housing expose a terminal end of each electrical contact. Openings in the rear portions of the housing allow connection of cables or other types of component wiring to the contacts. A locking tab is formed at the underside of the housing and functions to align and securely connect the special purpose modular connector with a correspondingly modified receptacle.

Abstract: A dispensing device for use in an implantable drug delivery system for ambulatory patients comprises a pump in a drug reservoir and a piezoelectric disc element bonded to a diaphragm member forming one wall of a pump chamber and a battery and electrical circuits for cyclically applying electrical voltage to the piezoelectric member for inducing pumping movement in the diaphragm member to pump drugs from a reservoir via a valve and to a delivery catheter via another valve. A gas spring is provided to move the pump to maintain adequate pressure in the drug reservoir.
