A system for externally locating the depth and orientation of a catheter in tissue with an external probe which generates a virtual rotating magnetic field. The catheter includes an inductive coil for developing an induced signal in response to the virtual rotating magnetic field. An indicating device such as a light bar display or digital readout indicates the strength of the induced signal for locating, independently of the relative angular orientation of the probe and the catheter, the depth in the tissue of the catheter.
A system for externally locating a sensor in tissue, comprising: an external probe including electronic means for providing a horizontal rotating magnetic field; a sensor for placement in tissue at a relative distance from said probe and at a relative angular orientation, in a horizontal plane, to s
A system for externally locating a sensor in tissue, comprising: an external probe including electronic means for providing a horizontal rotating magnetic field; a sensor for placement in tissue at a relative distance from said probe and at a relative angular orientation, in a horizontal plane, to said probe, in which the sensor develops an induced signal having a relative strength in response to said rotating magnetic field; means for determining the relative strength of said induced signal, independently of the relative angular orientation in the horizontal plane of said probe and said sensor; and means, responsive to said means for determining the relative strength of said induced signal, for indicating the relative distance between said probe and said sensor.
