Multi-lumen cardiac catheter and system



Multi-lumen cardiac catheter and system



Official Gazette of the United States Patent & Trademark Office Patents 1269(2), Apr 8



A system which includes a catheter and at least a first and second lead, where the catheter includes an elongate catheter body having at least two lumens through which the first and second leads pass. In one embodiment, the leads are reduced diameter leads having a complete, partial or no stylet lumen. The elongate catheter body further includes a first section and a second section, where there is a transition (e.g., a tapered portion) between the first section and the second section. A first lumen extends through the first section and the second section between a first inlet at the proximal end to a first outlet at the distal end. A second lumen extends through the first section between a second inlet at the proximal end to a second outlet at a point in the first section. In one embodiment, the second outlet is located approximately at the transition between the first section and the second section.
