Claim:
1. A method for operating a medical probe having a central shaft, comprising: pressing one or more of a plurality of arms each having a distal end that extends outward from the central shaft with each arm having a position transducer coupled thereto, against an intra-body surface, so as to cause the arms to exert pressure on the surface and bend with respect to the central shaft in response to the pressure; measuring positions of the respective position transducers coupled to the arms using a processor; and estimating, using the processor, the pressure exerted by at least one arm on the intra-body surface in response to the measured positions by calculating at least one angle between the central shaft and the at least one arm, and estimating, using the processor, the pressure responsively to the at least one angle.
