SPIRAL SENSOR FOR PHYSIOLOGIC SIGNAL MEASUREMENT WITH POSITION AND TISSUE PROXIMITY INDICATION

A sensor unit for a medical probe having coils that each have a respective central axis that is orthogonal to a longitudinal axis of the medical probe such that the coils are disposed one or more substrates. A first coil can have conductive surfaces exposed to an external environment while a second...

More Information
Summary:A sensor unit for a medical probe having coils that each have a respective central axis that is orthogonal to a longitudinal axis of the medical probe such that the coils are disposed one or more substrates. A first coil can have conductive surfaces exposed to an external environment while a second coil has its conductive surfaces insulated or sealed from the external environment. The coils can be configured to output 1) physiologic electrical signals (e.g., ECG) received at the at least two exposed windings, and 2) signals indicative of environmental impedance/conductance in the vicinity of the at least two exposed windings. The coils can further be configured to determine a position of the sensor based on magnetic field, determine a curvature of the sensor, directionally measure environmental impedance/conductance, and/or measure temperature.
