摘要： An implantable medication delivery device that is highly space efficient and can reliably and safely deliver controlled medication doses to a target site. The system includes a variable volume medication reservoir that is exposed to an ambient pressure equal to the ambient pressure at a system outlet port. A pump/valve subassembly is provided to draw medication from the reservoir and force a medication dose along a fluid transfer passageway to the outlet port. The pump/valve subassembly incorporates a safety mechanism, e.g., a balanced valve, which normally blocks medication flow to the outlet port and opens only in response to a pump induced unbalancing force. A protective shell is also disclosed for protecting the ambient reservoir.

摘要： A feedthrough connector for an implantable medical device includes a hermetically sealed housing containing an electrical circuit and a tubular barrel with an open end and a closed end defining a tubular channel that protrudes into the sealed housing while maintaining the seal of the housing. The inside of the tubular channel is open to the outside of the sealed housing through the open end and the tubular barrel also has a plurality of circumferentially spaced openings extending between an outer peripheral surface and the tubular channel. An electrical contact assembly electrically in common with the electrical circuit within the housing serves to make electrical contact with an electrical lead axially inserted into the open end of the tubular channel. The electrical contact assembly includes a plurality of contact members received in and projecting radially through a plurality of circumferentially spaced openings and a sleeve member of shape memory alloy freely overlies the contact members when in a first deformed-shape configuration but engage the contact members and the outer peripheral surface of the tubular barrel when in a second memory-shaped configuration, urging the contact members into mechanical, electrical, and hermetically sealed engagement with the electrical lead. The tubular channel may include a plurality of conductive cylindrical portions coaxial with the axis of the tubular barrel, the dimensions of the diameter of the successive cylindrical portions progressively decreasing from the open end to the closed end.

摘要： A mechanical drive system for use in driving a disposable cassette containing a reciprocating fluid pump and active valves from a main pump unit is disclosed which utilizes a single power module cam to drive both the reciprocating pump and the valves. By using a unitary power module cam, the system completely eliminates the possibility of a timing error between the operation of the reciprocating pump and the valves. A one-way clutch is used to prevent the system from slipping into a reverse operation, and the operation of the valve actuators prevents the possibility of free flow through a cassette installed onto the main pump unit.

摘要： A medication infusion pump is provided for controlled delivery of medication to a patient, wherein the pump includes a space-efficient flexible drive plunger for advancing a piston within a medication-containing syringe or cartridge for administration of the medication to a patient. The infusion pump comprises a compact housing defining a syringe chamber for receiving and supporting the barrel of a medication-containing syringe or cartridge having a nose end adapted for luer connection to catheter tubing through which the medication is delivered to the patient. An open rear end of the syringe barrel carries a piston which can be advanced in a controlled manner to dispense the medication. In the preferred form, the flexible drive plunger comprises a spring tape with a free end adapted for removable connection to the piston. The spring tape extends within the pump housing through a space-efficient curved path and is associated with a pump drive motor for advancing the piston within the syringe barrel to deliver the medication to the patient.
