1. A method of validating a position of a wirelessly powered electrostimulation device while the device is implanted in body tissue, the method comprising:
situating, using a catheter and a push rod configured to travel inside the catheter, the electrostimulation device in tissue;
pulling the push rod away from the electrostimulation device while electrodes of the device are in contact with the tissue; and
before an affixation mechanism of the electrostimulation device is deployed to maintain an implanted position of the electrostimulation device, after pulling the push rod away from the electrostimulation device, and while electrodes of the device are in contact with the tissue, performing electrical testing of the electrostimulation device to determine whether the electrostimulation from the electrostimulation device evokes a specified response from the body that contains the tissue.
