1. An implantable device configured to wirelessly receive power and/or data via a mid-field signal when the device is implanted inside a patient body, the implantable device comprising:
an antenna configured to receive a wireless power signal transmitted by a first external device;
a stimulator configured to apply an electrostimulation therapy to the patient tissue;
an energy storage circuit configured to store power from the wireless power signal received using the antenna; and
a control circuit configured to control the electrostimulation therapy and configured to control an electrostimulation pulse characteristic of the electrostimulation therapy based on a characteristic of the wireless power signal received using the antenna, wherein the control circuit and the electrostimulation therapy use the stored power from the energy storage circuit.
