First Claim
Patent Images
1. A device for implantation in a body, comprising:
- a receiver responsive to a trigger signal;
authentication circuitry coupled to the receiver and operative to distinguish an authentic trigger signal from a non-authentic trigger signal, the authentication circuitry being responsive to an authentic trigger signal to generate an actuation signal;
an actuatable member coupled to receive the actuation signal, the actuatable member being responsive to the actuation signal to change configuration; and
a physiological sensor configured to sense a physiological parameter in the body,wherein the receiver is configured to accept any one of a plurality of trigger signals, each trigger signal being associated with a respective permissions level, and wherein the authentication circuitry is operative to use the sensed physiological parameter together with the permissions level to distinguish an authentic trigger signal from a non-authentic trigger signal.
