Cardiac monitoring system and method with multiple implanted transponders |
摘要 |
A plurality of radio frequency semi-passive transponders are attached to an animal's organ, such as the heart. Each semi-passive transponder may be attached to the surface of the organ or mounted on a stent that is implanted in a blood vessel of the organ. An interrogator periodically sends a signal to each semi-passive transponder which reacts by transmitting a reply signal. The interrogator processes the reply signals to derive information regarding activity of the organ. In one embodiment, the position of each semi-passive transponder is determined from the reply signals, thereby enabling information about organ movement and volume change to be derived. In another embodiment, data from a sensor on the semi-passive transponder is sent via the reply signal.
