Abstract:
1. A catheter comprising: a flexible tubing having a proximal end and a distal end; an electrode assembly attached to the distal end of the flexible tubing and including a first magnet therein, the electrode assembly including an electrically conductive tip electrode and an electrically nonconductive coupler which is connected between the tip electrode and the distal end of the flexible tubing; wherein the electrically conductive tip electrode comprises a hollow elongated tip electrode including a sidewall provided with one or more elongated gaps extending through the sidewall, the one or more elongated gaps providing flexibility in the sidewall for bending movement of the tip electrode relative to a longitudinal axis of the flexible tubing, wherein the electrically conductive tip electrode comprises a flexibility that enables it to radially deform such that a cross sectional shape of the tip electrode is changed when the electrode impinges on a tissue surface; and wherein the first magnet is responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.
