1. Apparatus for treating an organ or vessel defining a cavity, the apparatus comprising:
- a catheter shaft adapted for insertion into the cavity, the catheter shaft having a distal region and a portion defining a groove,a guide member including an end effector to treat an interior wall of the hollow-body organ, the guide member disposed in the groove for translation along the catheter shaft;
means for disposing the end effector at a selected orientation relative to the catheter shaft; and
a stabilization assembly, disposed in the distal region, that stabilizes the catheter shaft and guide member within the organ or vessel during actuation of the end effector.

Abstract
Apparatus and methods for performing surgery within an organ or vessel 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 an organ or vessel, and for counteracting reaction forces developed during actuation of the end effector.

15. A method of treating an interior region of an organ or vessel comprising:
-
providing apparatus having a catheter shaft adapted for insertion into an organ or vessel, a guide member mounted in a groove on the catheter shaft and having an end effector for treating an interior region of the organ or vessel, and a stabilization assembly mounted on the catheter shaft; inserting the apparatus within an organ or vessel; deploying the stabilization assembly to stabilize the catheter shaft and guide member within the organ or vessel; translating the guide member within the groove of the catheter shaft to dispose the end effector at a selected location relative to the catheter shaft; and actuating the end effector to form a channel in an interior region of the organ or vessel. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of treating an interior region of an organ or vessel comprising:
-
providing apparatus having an outer sheath, a guide member extending from the outer sheath, the guide member including an end effector for treating an interior region of the organ or vessel; and
a stabilization assembly comprising a plurality of bands extendable from within the outer sheath, each one of the plurality of bands terminating in a spool that contacts an interior wall of the organ or vessel when extended;inserting the apparatus within an organ or vessel; extending the plurality of bands from the outer sheath to form spools, each spool contacting an interior wall of the organ or vessel to stabilize the guide member within the organ or vessel; translating the guide member to dispose the end effector at a selected location; and actuating the end effector to form a channel in an interior region of the organ or vessel.
