1. A medical device comprising:
- an implantable component which comprises a substrate having a plurality of discrete reservoirs which contain reservoir contents for selective release or exposure;
a rechargeable or on-demand power source which comprises a local component which is physically coupled to the implantable component, wherein the local component can wirelessly receive power from a remote transmitter; and
actuation electronics to selectively control and direct the power from the local component to selectively open the reservoirs to release or expose the reservoir contents.

Abstract
Devices and methods are provided for wirelessly powering and/or communicating with implanted medical devices used for the controlled exposure and release of reservoir contents, such as drugs or sensors. The device may include a substrate having a plurality of reservoirs containing reservoir contents for release or exposure; and a rechargeable or on-demand power source comprising a local component which can wirelessly receive power from a remote transmitter wherein the received power can be used, directly or following transduction, to activate the release or exposure of the reservoir contents.
