摘要：
In a flexible catheterization probe a resilient member couples the tip to thedistal portion ofthe probe and is configured to deform in response to pressure exerted on thetip when engagingtissue. A position sensor in the distal portion of the probe senses theposition of the tip relative tothe distal portion of the probe. The relative position changes in response todeformation of theresilient member. The position sensor generates a signal indicative of theposition of the tipresponsively to a magnetic field produced by a magnetic field generatorlocated in the positionsensor. The position sensor has a first coil of conductive wire having firstwindings, and three secondcoils of conductive wire having respective second windings. The second coilsare symmetricallydistributed about the longitudinal axis of the first coil.
