Electrosurgical devices with directional radiation pattern

摘要

ELECTROSURGICAL DEVICES WITH DIRECTIONAL RADIATION A device for directing energy to a target volume of tissue, comprising: an elongated body member (400), including: a body wall (450) defining a chamber (480) therein; and an outer jacket (458) formed of an electrically conductive material; and an antenna assembly (12) disposed in the chamber (480), wherein the elongated body member (400) includes an opening (440) in the body wall (450) to allow energy radiated from the antenna assembly (12) to transfer into the target volume of tissue.
