Patent ID: 8588886

Claim:
A catheter comprising: an elongated catheter body having a proximal end and a distal end, and at least one lumen therethrough in a longitudinal direction of the elongated catheter body; a handle connected to the proximal end of the elongated catheter body, wherein the handle is configured to deflect the distal end of the elongated catheter body; an electrode assembly at the distal end of the catheter body, the electrode assembly comprising a plurality of spines, each of the spines having a proximal end connected to the distal end of the catheter body and a distal end, the distal ends of the spines being connected at a tip junction, wherein each spine includes an elbow, wherein the spines include a plurality of electrodes; and a tilting mechanism to tilt the electrode assembly with respect to the elongated catheter body; wherein the electrode assembly is sized and configured to fit in a sheath in a collapsed arrangement and is configured to expand to an expanded arrangement with the elbows of the spines bending outwardly relative to the proximal and distal ends of the spines, the elbows of the spines moving radially outwardly from the collapsed arrangement to the expanded arrangement.
