Abstract

An electrode apparatus may include a handle, a cannula extending from a distal end of the handle and having at least one lumen, a ground wire extending through the cannula, and an electrode wire extending through the handle and the cannula, the electrode wire being extendable and retractable relative to a distal end of the cannula. The apparatus may also include a hook, provided in the cannula, and being extendable and retractable relative to the cannula.

First claim

What is claimed is:

1 . An electrode apparatus, comprising:
a handle; a cannula extending from a distal end of the handle, wherein the cannula includes at least one lumen therein; a ground wire extending through the cannula; an electrode wire extending through the handle, and through the cannula, the electrode wire being extendable and retractable relative to a distal end of the cannula; a pusher rod extending from the handle, through the cannula, alongside the electrode wire; and a hook provided on a distal end of the pusher rod, the hook being extendable and retractable relative to the cannula.

2 . The electrode apparatus of claim 1 , wherein a distal end of the electrode wire is in a looped configuration.

3 . The electrode apparatus of claim 1 , wherein the electrode wire is a single, un-looped, electrode wire.

4 . The electrode apparatus of claim 1 , further comprising a trigger mechanism, provided on the handle and operably coupled to the hook via the pusher rod, and being configured to move the hook in one of a distal direction and a proximal direction, upon compression of a trigger of the trigger mechanism, and to move the hook in the other one of the distal direction and the proximal direction, upon release of the trigger.

5 . The electrode apparatus of claim 1 , further comprising a slide mechanism, provided on the handle and operably coupled to the electrode wire, and being configured to move the electrode wire in one of a distal direction and a proximal direction, upon translation of a slide to a distal position within a slot, and to move the electrode wire in the other one of the distal direction and the proximal direction, upon translation of the slide to a proximal position within the slot.

6 . The electrode apparatus of claim 1 , further comprising a thumbwheel, provided on the handle and operably coupled to the electrode wire, and being configured to move the electrode wire in one of a distal direction and a proximal direction, upon rotation of the thumbwheel in a distal direction, and to move the electrode wire in the other one of the distal direction and the proximal direction, upon rotation of the thumbwheel in a proximal direction.

7 . The electrode apparatus of claim 6 , further comprising an indicator window, provided on the handle, and configured to display a flag when the electrode wire is retracted into the distal end of the cannula.

8 . The electrode apparatus of claim 1 , wherein the electrode wire is formed of a biocompatible material.

9 . The electrode apparatus of claim 8 , wherein the biocompatible material is selected from the group consisting of: Nitinol®, copper, annealed copper, gold plated copper, and gold plated wire.

10 . The electrode apparatus of claim 1 , wherein the electrode wire is formed of stranded wire.

11 . The electrode apparatus of claim 5 , further comprising an indicator window, provided on the handle, and configured to display a flag when the electrode wire is retracted into the distal end of the cannula.

12 . The electrode apparatus of claim 1 , wherein a distal end of the hook is rounded.

13 . The electrode apparatus of claim 1 , wherein the hook has a protrusion on one surface thereof for grasping a distal end of the electrode wire.

14 . The electrode apparatus of claim 1 , further comprising an insert provided within a distal end of the cannula, the insert having a T-shaped divider at a distal end thereof forming a plurality of openings through which the ground wire, the electrode wire, and the hook are configured to extend.

15 . The electrode apparatus of claim 14 , wherein the insert further as a circumferential slot, and the ground wire is configured to be inserted into the circumferential slot.

16 . The electrode apparatus of claim 1 , wherein one or more proximal portions of the electrode wire are insulated, and a distal portion of the electrode wire is not insulated.

17 . The electrode apparatus of claim 1 , wherein the electrode wire has a welded tip without insulation, and a distal end of the electrode wire is located distally of the hook.
