1. An implantable device for controllably ejecting fluid into an anatomic region, the device being shaped to conform to an anatomic implantation site and comprising:
- a fluid storage reservoir;
a pump mechanism for pumping fluid from the reservoir into the anatomic region;
circuitry for controlling the pump mechanism, the circuitry comprising a receiver for receiving wireless communications from an external transmitter and, operatively coupled to the receiver, an antenna comprising at least one spiral coil,wherein the device has a non-planar contour and the spiral coil comprises a plurality of windings of increasing diameter around a central point, the windings not being in lateral electrical contact with each other, and defines a non-planar surface conforming to the non-planar contour.

Abstract
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.
