    摘要： A medical device system comprises a reservoir configured to store a therapeutic fluid and a medical pump configured to deliver the therapeutic fluid from the reservoir to a patient. The system also comprises a sensor that can detect a characteristic associated with the pump and a processor to determine if the characteristic detected indicates the reservoir is empty or near empty. The characteristic may comprise a characteristic of a noise made by an actuator within the pump at the end of a pump stroke.

    摘要： An implantable medical device system includes an implantable device and an external locator device for percutaneously locating detecting port opening of the implantable device. The implantable device includes a port chamber forming the port opening, a septum sealing the port chamber relative to an exterior of the device, and a coil positioned at a known location relative to the port opening. The locator device includes a controller, at least one X-loop electrically coupled to the controller and oriented along a first major axis, and at least one Y-loop electrically coupled to the controller and oriented along a second major axis differing from the first major axis. The system is configured such that when the locator is spatially proximate the coil, an induced voltage in at least the Y-loop(s) is read by the controller to indicate a location of the coil relative to the locator device.

    摘要： An implantable drug delivery device includes a pump motor that is asserted by drive currents from a storage capacitor. A programmable rate charge control delivers charging current from a battery to the storage capacitor based upon a programmable charge rate value, a minimum battery voltage value, sensed charging current, and sensed battery voltage. When sensed battery voltage droops to below a threshold value, the charge control reduces the charging rate value until other electrical loads within the drug device have been serviced and battery voltage is restored. The charge control also monitors capacitor voltage and provides a charge complete signal to a motor control, which then connects the pump motor to the storage capacitor to produce a pump stroke. Efficiency of charging is enhanced by controlling the charging at a programmable substantially constant rate.
