An implantable medical device assembly comprises a sealed housing; a motor including a rotating output shaft within the sealed housing; a first coaxial shaft within the sealed housing, the first coaxial shaft being mechanically coupled to the rotating output shaft such that rotation of the rotating output shaft drives rotation of the first coaxial shaft; a second coaxial shaft external to the sealed housing, the second coaxial shaft being in axial alignment with the first coaxial shaft; an oscillating component mechanically coupling the first coaxial shaft to the second coaxial shaft, wherein rotation of the rotating first coaxial shaft drives the oscillation of the oscillating component, wherein the oscillation of the oscillating component drives rotation of the second coaxial shaft; and a flexible seal including the oscillating component. The sealed housing and the flexible seal combine to form a substantially sealed enclosure encasing the motor and the first coaxial shaft.

Mechanical feedthroughs for implantable medical device

A therapeutic fluid delivery device that includes at least one controllable valve is generally described. In one example, an implantable therapeutic fluid delivery system includes a first fluid pathway configured to convey a first therapeutic fluid and a second fluid pathway configured to convey a second therapeutic fluid, the second fluid pathway being separate from the first fluid pathway. The therapeutic fluid delivery system includes a valve connected to the first fluid pathway and the second fluid pathway, and a processor configured to control actuation of the valve to open and close the first fluid pathway and to open and close the second fluid pathway.

Drug infusion device with controllable valve

A device and method for aseptically filling high pressure reservoirs in medicament pumps is disclosed. The device preferably includes a filter, a connector having a one-way valve and a filling tube with a terminal needle. The filter is connectable to a pharmacy prepared syringe containing a drug to be transferred to the reservoir of the IDIP. The filter is connected to the connector. The connector has a first and a second inlet port fluidly connected to an outlet port. A one-way valve is located in the connector &ldquo;upstream&rdquo; of the point where the two inlet ports connect to the outlet port. The filling tube is connectable to the outlet port. In use, a pharmacy syringe is connected to the first inlet port. A filling syringe is connected to the second inlet port. The filling tube is connected to the outlet port. The terminal needle of the filling tube is passed through the patient's skin and into the IDIP. The practioner draws the drug into the filling syringe from the pharmacy syringe through the connector. When the filling syringe is full, the practioner pushes the filling syringe plunger in thereby forcing the drug out of the outlet port, through the filling tube and terminal needle into the reservoir of the IDIP. The one-way valve prevents the drug from re-entering the pharmacy syringe.
