Patent attributes
A tissue visualization and modification device may include a rigid access body having a longitudinal axis, an internal passageway extending from the proximal end to the distal end, and an access body imaging sensor positioned on the distal end of the body and protruding inward beyond an inner wall into the internal passageway. An elongated member may be slidably positioned within the rigid access body. The elongated member may include, when viewed substantially along the longitudinal axis, a dissection electrode in the shape of a semicircle, an irrigation channel positioned within the semicircle, an aspiration channel positioned partially within the semicircle and adjacent the irrigation channel, first and second illumination elements positioned adjacent the respective tips of the semicircle and an elongated member imaging sensor positioned adjacent the aspiration channel.
