摘要： Techniques for minimizing interference between first and second medical devices of a therapy system may include providing an outer housing for at least one of the medical devices that comprises an electrically insulative layer formed over at least the electrically conductive portions (e.g., an electrically conductive layer) of the housing, or providing an electrically insulative pouch around an electrically conductive housing of at least the first medical device. The electrically insulative layer or electrically insulative pouch may reduce or even eliminate shunt-current that flows into the medical device via the housing. The shunt-current may be generated by the delivery of electrical stimulation by the second medical device. In some examples, the techniques may also include shunt-current mitigation circuitry that helps minimize or even eliminate shunt-current that feeds into the first medical device via one or more electrodes electrically connected to the first medical device.

摘要： A medication delivery device having a reduced weight due to the configuration of the end terminal of the pleated bellows reservoir. The end terminal includes an indented portion which is sized such that when the reservoir is in the compressed/empty position there is substantially no separation between the indented portion and the base portion of the reservoir. This construction allows the reservoir to be almost completely emptied of medication when the reservoir is collapsed but does so in a manner which does not add to the weight of the device.

摘要： A medication delivery device having a particularly compact size due to the bulged configuration of the cover. The device includes a housing having a base and a cover. The cover includes a side portion and a substantially planer surface joined by a curved portion. The curved portion is bulged outwardly in a manner such that the area of the internal cavity bounded by the side portion, the substantially planer surface and the base includes substantially all of the area which would be formed if the side portion and the substantially planer surface were extended and joined in the absence of the curved portion. This enables the entire vertical space of the internal cavity to be utilized and allows the thickness of the device to be minimized.

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： An bolus delivery system includes an implantable pump, a sensor for sensing an adverse patient condition, such as atrial fibrillation, and a catheter for delivery of a bolus of drug to a target area of a living body. The pump is provided with a bolus metering assembly which includes, in a preferred embodiment, an auxiliary bellows defining a bolus reservoir in addition to the main reservoir of the pump. The auxiliary bellows is selectively placed in fluid communication with the pressurized main supply of drug via an inlet valve to refill the bolus reservoir. An outlet valve is provided to permit egress of the bolus to the catheter from the bolus reservoir. A drive train including a stepper motor and a face cam selectively opens and closes the inlet and outlet valves to effect accumulation or metering and delivery of the bolus. The auxiliary bellows is preferably provided as a collapsible element resiliently biased to an expanded position and is collapsed under pressure in the main reservoir to expel the bolus.
