Patent ID: 7588554

Claim:
A device for treating tissue comprising: an elongate shaft having a proximal end, a distal end, and a lumen extending between the proximal end and the distal end; at least one injury effector located at the distal end of the elongate shaft, capable of producing an injury at a first tissue location, and having no therapeutic substance delivery capabilities; at least one therapeutic substance delivery effector located at the distal end of the elongate shaft, capable of delivering a therapeutic substance to a second tissue location; and at least one marking effector located at the distal end of the elongate shaft for creating a position marker at a third tissue location to indicate treated tissue; wherein the at least one marking effector is separate from the at least one therapeutic substance delivery effector; wherein the at least one injury effector and the at least one marking effector are capable of being sequentially actuated by a control structure; wherein the lumen is in substance communication with the at least one therapeutic substance delivery effector and at least a portion of the lumen is configured to receive the therapeutic substance; and wherein at least a portion of the at least one injury effector passes through, and is electrically isolated from, the portion of the lumen configured to receive the therapeutic substance.
