1. An apparatus for performing a diagnostic or therapeutic operation on body tissue, comprising:
- a support structure defining a proximal region and a distal region;
first and second longitudinally spaced conductive regions associated with the distal region of the support structure; and
an actuation device including at least one electrical contact located within the support structure and movable between a first position where the at least one electrical contact is in electrical connection with the first conductive region and a second position where the at least one electrical contact is in electrical connection with the second conductive region.
