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.
Claims19
An electrode structure, comprising:
- an electrically conductive base;
- an electrode;
- and
- a joint that secures the electrode relative to the base, the joint being movable between a first position where the base and electrode are electrically disconnected from one another and a second position where the base and electrode are electrically connected to one another.
1 more element
A probe, comprising:
- a probe shaft defining a distal end;
- an electrode carried by the distal end of, and movable relative to, the probe shaft;
- a power wire;
- and
- a switch, operably connected to the electrode and the power wire, adapted to electrically disconnect the electrode from the power wire when the electrode is in a first position relative to the distal end of the probe shaft and to electrically connect the electrode to the power wire when the electrode is in a second position relative to the distal end of the probe shaft.
2 more elements
A probe, comprising:
- a probe shaft defining a distal end;
- an electrode carried by the distal end of the probe shaft;
- a power wire;
- and
- means, located adjacent to the distal end of the shaft, for electrically connecting the electrode to the power wire in response to the application of a predetermined force to the electrode.
