Abstract: This invention relates to methods, apparatuses and systems for testing the functionality of the pumping mechanism of a medical device, e.g., an implantable infusion pump, while the medical device is contained within a shipping package. The test apparatus enables such functional verification, without opening the shipping package, when the medical device is still contained within the package that has been appropriately sealed to maintain sterility of the medical device.

Abstract: An implantable medication delivery apparatus including a flow path coupling a medication reservoir to a device outlet port where the flow path includes a regulator means for limiting the magnitude of pressure transferred downstream from the medication reservoir. The regulator means is configured to respond to the reservoir pressure exceeding a certain threshold for closing a valve located downstream from the reservoir. The valve closure functions to isolate the device outlet port from further reservoir pressure increases which otherwise could induce unintended medication flow from the device outlet port.

Abstract: A medical device needle receiving port configured to stop a needle's penetration without physically engaging the needle's tip thereby reducing the likelihood of tip damage. The port preferably incorporates a particulate chamber for collecting particulates larger then a fluid outlet dimension.

Abstract: An electromagnetic coil assembly comprising a spool-spindle and a case. The spool-spindle comprises a spindle portion and a larger included portion. The spindle portion has a conductor wound thereon. The larger included portion has opening for receiving the conductor. The case has a first case end and a second case end, with an opening extending through the case. A first internal surrounding surface extends from the second case end and a second surrounding internal surface having a smaller diameter extends from the first case end. The first internal surrounding surface meets the second internal surrounding surface at an annular internal wall. The spool-spindle is positioned in the case until the larger include portion abuts against the annular internal wall, and the case and spool-spindle are joined.

Abstract: The present invention relates to an implantable drug delivery device which includes a fluid drug reservoir, a catheter, a controllable fluid transfer device, e.g., a pump or valve, and a drug delivery control means. The control means in accordance with the invention is configured to initially clear a first, or old, drug from the device based on the content of the Current Profile data containing a first, or old, delivery profile. After the old drug is cleared, then the control means automatically modifies the Current Profile data to match a second, or new, delivery profile for controlling delivery of a second, or new, drug.
