Development and evaluation of denervation catheter by use of microwave energy

摘要

In recent years, various types of medical applications of microwave have widely been investigated and reported. In this paper, a catheter, which ablates extravascular nerve by the thermal effect of microwave, is introduced. In addition, heating characteristics of the catheter are evaluated by numerical calculations. As a result, temperature distributions around the catheter were revealed and the usefulness of a denervation catheter using microwave was suggested.
