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