1. A probe, comprising:
- a probe shaft defining a distal end;
an electrode associated with the distal end of the probe shaft;
a power wire; and
a switch includingan electrically conductive base mounted directly onto the distal end of the probe shaft and connected to the power wire, anda joint that secures the electrode to the electrically conductive base such that the electrode is movable between a first position where the electrically conductive base and electrode are electrically disconnected from one another and a second position where the electrically conductive base and electrode are electrically connected to one another.

Abstract
Probes that are sensitive to electrode/tissue contact and that are configured to connect an electrode to a power supply and/or provide an indication when the desired level of electrode/tissue contact has been achieved.

6. A probe, comprising:
-
a probe shaft defining a proximal end and a distal end; an electrode carried by the distal end of the probe shaft; a sensor wire extending through the probe shaft to the electrode; means for conducting tissue coagulation enemy from the proximal end of the probe shaft to the distal end of the probe shaft; and means, located adjacent to the distal end of the shaft, for electrically connecting the electrode to the means for conducting tissue coagulation energy in response to the application of a predetermined force to the electrode. - View Dependent Claims (7, 8)
