    摘要： An implantable drug infusion device includes a bulkhead having a chamber and a shield for the bulkhead. A transducer is secured to the shield. An electronic module is located in the bulkhead for controlling operation of a pump assembly. A biasing member is in electrical contact with the electronic module and the transducer such that current transmitted from the electronic module to the transducer through the biasing member actuates the transducer.

    摘要： A human body implantable drug delivery pump has a housing including at least a first shield and a second shield. The housing defines an interior within the shields. The pump further includes a fluid reservoir within the housing, a fluid conduit also within the housing from the reservoir, an outlet from the fluid conduit to the exterior of the housing, and a pump member in the housing adapted to move fluid through the fluid conduit to the outlet. The fluid in the reservoir and fluid conduit is isolated from the pump interior. The pump further has a desiccant in the pump interior, the desiccant absorbent of moisture in the pump interior, and preferably absorbent of substantially all the moisture in the pump interior. The desiccant also preferably has a moisture absorbent property dependent on temperature, being lessened at higher temperatures, the desiccant being pre-baked to improve its moisture absorbent property before being placed in the pump.

    摘要： Changes in electrical stimulation therapy delivered via a medical device are coordinated with Functional Magnetic Resonance Imaging (fMRI) scans. In one example, a medical device delivers electrical stimulation therapy to a patient in an MRI unit, where the medical device is configured to cycle electrical stimulation therapy between a plurality of stimulation states. An indication that the medical device will cycle the electrical stimulation therapy or has cycled the electrical stimulation therapy while the patient is in the MRI unit or being imaged by the MRI unit is generated, and an MRI scan of the patient via an MRI workstation is initiated based on the indication. In another example, a medical device detects activation of an MRI scan and automatically switches stimulation states based upon the detection of the MRI scan, such that the scan is associated with a particular stimulation state.

    摘要： An improvement to silicone insulation for implantable medical electrical leads includes a plurality of ultra high molecular weight polyethylene multi-filament fibers, wherein each of the plurality includes approximately 25 monofilaments and has a titer of approximately 25. The plurality of fibers are embedded within a wall of the insulation that has a thickness of no greater than approximately 0.008 inch. A first fiber of the plurality preferably extends helically, and a second fiber of the plurality preferably extends linearly such that the second crosses over or under and directly adjacent to the first at a plurality of points, which are spaced apart from one another along an overall length of the silicone insulation. The aforementioned wall thickness is maintained, since, at least at each crossing point of the first and second multi-filament fibers, a coincident cross-section of each of the fibers is compressed in the radial direction.

    摘要： Implantable medical leads and implantable lead extensions include a shield. The implantable medical lead is coupled to the implantable lead extension. Stimulation electrodes of the implantable medical lead contact stimulation connectors within a housing of the implantable extension to establish a conductive pathway for stimulation signals from filars of the implantable extension to filars of the implantable medical lead. Continuity is established between the shield of the implantable medical lead and the implantable extension by providing a radio frequency conductive pathway within the housing. The radio frequency conductive pathway extends from a shield of the implantable extension to a shield connector that contacts a shield electrode of the implantable medical lead. The radio frequency conductive pathway may have various forms such as a jumper wire or an extension of the shield within the implantable extension.
