Original Abstract Submitted

a basket catheter and system is configured to determine a force on a basket assembly of the basket catheter and/or determine deformation of the basket assembly by using a sensor assembly in the basket catheter which includes a transmitting coil and multiple receiving coils in the catheter shaft and an electrically conductive plate, disk, or ring at a distal end of the basket assembly. the system is configured to provide signals to the transmitting coil to generate a first magnetic field that in turn causes eddy currents in the electrically conductive plate, disk, or ring, that in turn generates a second magnetic field. the receiving coils detect a superposition of the first and second magnetic fields, and the system determines the force and/or deformation based at least in part on the signals from the receiving coils.
