CATHETER SYSTEM FOR ACUTE NEUROMODULATION

摘要

A neuromodulation system includes a first therapy element adapted for positioning within a superior vena cava, and a second therapy element adapted for positioning within a pulmonary artery. Each therapy element is carried on a corresponding elongate flexible shaft. One of the shafts is slidably received within a lumen of the other so that the second therapy element may be advanced within the body relative to the first. A stimulator energizes the first therapy element within the first blood vessel to deliver therapy to a first nerve fiber disposed external to the superior vena cava and to energize the second therapy element within the pulmonary artery to deliver sympathetic therapy to a second nerve fiber disposed external to the pulmonary artery. For treatment of heart failure, the first nerve fiber may be a vagus nerve and the second nerve fiber may be a sympathetic nerve fiber.
