SUMMARY [57] An apparatus (20) and method for performing a surgery in a hollow body organ is provided. A catheter (28) is provided having a longitudinal axis and a distal region with an end effector (25), the distal region being selected along and along the longitudinal axis. In the orientation, it can be moved to a series of positions. The catheter (28) includes elements (27) for stabilizing the distal region of the device within the hollow body organ and for counteracting the reaction forces generated during operation of the distal effector (25). The end effector (25) performs tissue cutting and suction of the dissected tissue from the treatment site. |
