摘要:
A catheter adapted to determine a contact force, the catheter including a proximal segment, a distal segment, and an elastic segment extending from the proximal segment to the distal segment. The distal segment includes a plurality of tip electrodes including at least three radial electrodes disposed about a circumference of the distal segment. The radial electrodes are configured to output electrical signals indicative of a contact vector of the contact force. The elastic segment includes a force sensing device configured to output an electrical signal indicative of a magnitude of an axial component of the contact force, wherein the contact force is determined by scaling the magnitude of the axial component of the contact force by the contact vector.
