METHOD OF TREATING A LIVING BODY TISSUE |
摘要 |
A method is disclosed for treating a living body tissue by cauterizing a sympathetic nerve around a renal artery to block a neurotransmission function of the sympathetic nerve. The method includes inserting a balloon catheter including a balloon on a distal end side of a shaft into a body cavity, and delivering the balloon to the renal artery; inflating the balloon that has been delivered to the renal artery; puncturing a blood vessel wall with at least one protrusive member disposed on an outer surface of the balloon when the balloon is inflated; and after puncturing the blood vessel wall with the protrusive member, cauterizing the sympathetic nerve within a region at a periphery of an electrode disposed on a projecting tip end portion of the protrusive member by supplying a current to the electrode. |
