Abstract
Apparatus and methods for performing surgery within a hollow-body organ are provided. A catheter is provided having a longitudinal axis and an end region carrying an end effector, the end region movable to a series of positions along the longitudinal axis and with an selectable orientation relative to the longitudinal axis. The catheter includes elements for stabilizing the end region of the apparatus within a hollow-body organ, and for counteracting reaction forces developed during actuation of the end effector. The end effector provides for tissue cutting and aspiration of severed tissue from a treatment site.
