Abstract
An apparatus for detecting a surgical implement in human or animal tissue comprises a battery powdered marker. The marker is secured to the surgical implement and positioned within a surgical wound. A detection means has an antenna disposed in close proximity of the tissue. Means are provided for capacitance coupling of both the marker and the antenna to the tissue. A field generating means generates an electromagnetic field having a predetermined frequency band within the tissue and a signal generating means generates a signal having a predetermined frequency band ranging from about 10 MHz to 1 GHz. The signal generated by the signal generating means causes the field generating means to generate the electromagnetic field providing the marker with signal identity.
