Systems and methods for determining a contact angle of a catheter relative to tissue are provided. In one embodiment, a system includes a catheter with three or more electrodes, and a processor circuit in communication with the catheter. The processor circuit controls the three or more electrodes to emit a plurality of electrical voltages and to measure the plurality of electrical voltages. Based on the measured electrical voltages, the processor circuit calculates a first interelectrode impedance and a second interelectrode impedance. The processor circuit calculates, for each of a plurality of hypothetical i.e. model angles, a first hypothetical i.e. model contact force and a second hypothetical i.e. model contact force based on the first and second interelectrode impedances. The processor circuit determines and outputs the contact angle of the catheter based on a comparison of the first and second model contact forces calculated for each of the plurality of model angles.
A method of determining a contact angle between a catheter and tissue within a body, the method comprising:
An apparatus, comprising:
A non-transitory computer-readable storage medium having stored a computer program comprising instructions, which, when executed by a processor, cause the processor to:
