Abstract
A method of performing denervation with a cooled microwave denervation catheter assembly includes advancing a catheter body over a guide wire in a body lumen of a patient to a treatment location adjacent targeted nerves, with the guide wire being located in an interior lumen of the catheter body, inflating the balloon with cooling fluid to contact a wall of the body lumen of the patient, removing the guide wire from the interior lumen of the catheter body, and inserting a microwave antenna catheter into the interior lumen of the catheter body, so that denervation treatment may be performed by simultaneously circulating cooling fluid in the balloon and supplying power to the microwave antenna, to cause the targeted nerves to be heated to a temperature sufficient to cause thermal damage while the wall of the body lumen is maintained at a temperature where thermal damage does not occur.
