Patent ID: 7611482

Claim:
A medical device instrument comprising: an autonomous minimally invasive medical device on a distal portion of the medical device instrument, the medical device comprising: a first environmental condition sensor carried by the minimally invasive medical device adapted to detect a first environmental condition at a target site in the body of a patient adjacent to the medical device and adapted to transmit a first signal based on the first environmental condition; and a second environmental condition sensor carried by the minimally invasive medical device adapted to detect a second environmental condition at the target site in the body of the patient adjacent to the medical device and adapted to transmit a second signal based on the second environmental condition; and a plurality of actuators comprising: a first actuator carried by a first portion of the medical device adapted to receive the first signal and to actuate to deliver therapy to the patient at the target site if the first signal meets a first predetermined condition and to inhibit actuation if the first signal does not meet the first predetermined condition; a second actuator carried by a second portion of the medical device adapted to receive the second signal and to actuate to deliver therapy to the patient at the target site if the second signal meets a second predetermined condition and to inhibit actuation if the second signal does not meet the second predetermined condition, wherein the plurality of environmental condition sensors and the plurality of actuators cooperate to autonomously determine whether to actuate the first actuator and the second actuator of the medical device, and wherein the first signal, the second signal, or both is a mechanical signal.
