Abstract:
1. An electrophysiology catheter comprising: a tubular catheter body having a proximal region, a neck region, and a distal region predisposed into at least a partial loop disposed in a plane; a plurality of electrodes disposed on the distal region; a handle joined to the proximal region; a first deflection wire extending through at least a portion of the proximal region of the catheter body and including a first flattened section; a second deflection wire extending through the neck region and at least a portion of the distal region and including a second flattened section within the neck region; a first activation wire extending from the handle and joined to the first flattened section of the first deflection wire such that forces acting on the first activation wire are transmitted to the first deflection wire in order to deflect the proximal region of the tubular catheter body such that the at least a partial loop of the distal region deflects from the plane; and a second activation wire extending from the handle and joined to the second flattened section of the second deflection wire such that forces acting on the second activation wire are transmitted to the second deflection wire in order to deflect the neck region of the tubular catheter body such that the at least a partial loop of the distal region deflects from the plane.
