1. An ablation device comprising:
- an endoscope having a central longitudinal axis;
a support platform having a proximal end, a distal end and a central longitudinal axis extending between the proximal and the distal end;
an ablation structure having a proximal end, a distal end and an electrode surface, the ablation structure is supported by the support platform whereby the electrode surface faces away from the central longitudinal axis of the support platform; and
a flexible coupling mechanism that encircles an exterior surface of the endoscope and attaches to the support platform between the proximal and the distal ends of the electrode surface.

Abstract
Apparatus for treating abnormal mucosa in an alimentary tract are provided. The apparatus include an ablation structure configured to be removably coupled to an endoscope and a deflection mechanism adapted to move the ablation structure with respect to the endoscope and toward a tissue surface.

3. An ablation device comprising:
-
an endoscope having a central longitudinal axis; a support platform coupled to a distal portion of the endoscope, the support platform having a central longitudinal axis; an ablation structure supported on a surface of the support platform that faces away from the central longitudinal axis of the endoscope; and a coupling mechanism connected between the proximal and distal ends of the support platform and between the proximal and distal ends of the ablation structure while allowing pivoting movement between the central longitudinal axis of the support platform and the central longitudinal axis of the endoscope. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. An ablation device comprising:
-
an endoscope having a central longitudinal axis; a support platform coupled to a distal portion of the endoscope, the support platform having a longitudinal axis; an ablation structure supported on a surface of the support platform that faces away from the central longitudinal axis of the endoscope; and a coupling mechanism connected between the proximal and distal ends of the support platform and between the proximal and distal ends of the ablation structure while allowing pivoting movement of the support platform about an axis transverse to the central longitudinal axis of the endoscope.
