<p>An apparatus for treating a portion of a wall forming a cavity in a body. The apparatus includes an elongate probe member (31), a suction source (86) and an energy source (32). The elongate probe member (31) includes a distal extremity (84) which has an outer surface, at least one recess opening (98) onto the outer surface, and an internal passageway (103) communicating with the recess (98). The suction source (86) is coupled to the elongate probe (31) and is in communication with the passageway (103) to create suction in the recess (98) for drawing a portion of the wall into the recess (98). At least one stylet (71) is carried by the elongate probe member (31) and is extendable into the recess (98). The energy source (32) is coupled to the stylet (71) for delivering radio frequency energy through the stylet (71) to the wall for treatment thereof.</p> |
