Abstract
A system and method for detecting a surgical implement retained within a surgically exposed human body cavity, includes a tag adapted to be attached to a surgical implement insertable within a human body cavity, including a receiver for receiving an electromagnetic signal and converting it into electric signal; and a circuit to impress said electric signal on the internal human (or an animal) body where the medical product is used; and a transmitter to transmit the electromagnetic signal; and a detector including a receptor for receiving the electric signal from the body and a detector connected to the receptor for detecting the electric signal. The envelope of the induced RF wave is demodulated, thus allowing the voltage at the output to vary at a significantly lower frequency. In the event such pulses are sensed, a sensory alert is actuated.
