Microwave balloon angioplasty

摘要

A microwave catheter system used for heating arterial plaque and including a catheter member adapted for positioning in the artery and an inflatable balloon supported at the distal end of the catheter member. Microwave energy is coupled by means of a transmission line to an antenna means. An optic fiber extends through the catheter member and may be used for temperature sensing or other purposes. A channel is provided through the catheter member for coupling a fluid to the balloon for inflation thereof.
