Flexible ablation instrument

摘要: A flexible microwave antenna assembly for a surgical ablation instrument capable of conforming to tissue surface thereof. The includes transmission line having proximal portion suitable connection an electromagnetic energy source. coupled the radially generating electric field sufficiently strong cause ablation. shield device is substantially surrounding area from generated therefrom while permitting majority be directed generally in predetermined direction. insulator disposed between and which defines window enabling antenna, are formed selective manipulative bending thereof, as unit, one plurality contact positions conform biological ablated.
