Abstract:
1. A catheter assembly for use in an anatomy comprising: an elongated body having body wall, a proximal end defining a first outer diameter, and a distal end defining a second outer diameter, and defining a lumen from the proximal end to the distal end; at least one electrode coupled to the distal end that senses an electrical activity within the anatomy; a core wire received within the lumen extending from the proximal end to the distal end and bonded with at least a portion of the elongate body, the core wire configured to move the distal end from a first configuration to a second configuration; and a necked portion formed between the proximal end and the distal end and providing increased stiffness to the distal end of the body, the necked portion having a third outer diameter that is less than each of the first and second outer diameters, and a thickness of the body wall of the elongate body being the same in the proximal end, the necked portion, and the distal end.
