摘要:
A tissue surface treatment apparatus includes a housing having a proximal end, a distal including a tissue contacting surface and an interior defined by the housing. A handpiece is coupled to the housing. The tissue contact surface has a plurality of apertures. An energy delivery device including at least one electrode is positionable in the housing interior. The at least one electrode includes a tissue penetrating distal end in substantial alignment with an aperture of the plurality of aperture. The at least one electrode is configured to be advanced from the housing interior through the aperture and into a target tissue site to define an ablation volume at least partly bounded by a tissue surface. An advancement device is coupled to the energy delivery device. The advancement device is at least partly positionable within at least one of the housing or the handpiece. The advancement device is configured to advance the at least one electrode from the housing interior into the target tissue site and completely withdrawal the at least one electrode into the housing interior. A cable is coupled to one of the housing or the energy delivery device. The cable is configured to be coupled to an energy source.
