摘要:
Embodiments of an implantable electrolytic pump include a drug reservoir, a cannula fluidly coupled to the reservoir, a pumping mechanism for forcing liquid from the reservoir through the cannula, control circuitry for operating the pumping mechanism, and a power source comprising primary and auxiliary batteries in a stacked configuration, only the main battery being operatively coupled to the control circuitry during normal operation, the control circuitry operatively coupling the back-up battery upon detection of an electrical fault. The pump may further include a hermetic enclosure containing the control circuitry and the power source.

A spiral-coil antenna conforming to a non-planar contour is deployed, in various embodiments, in an implantable device for controllably ejecting fluid into an anatomic region. The antenna facilitates wireless communications with the implantable device and external charging thereof. In one implementation, the device has a non-planar contour and the spiral coil defines a non-planar surface conforming to the non-planar contour.
