Embodiment Construction

[0103] 【00103】 figure 1 Shown are two main components and one optional component, which are energy generator 400, probe 371 (in Figure 3A Various probes are described in -D) and optionally probe 771 or 772 may be used.

[0104] [00104] In normal operation, the novel stylet 371 will incorporate a unique bipolar configuration in a single MIS needle, which is inserted into the patient using MIS technology. A probe, which may contain and / or deliver the various functions described below, is initially anatomically guided to a region of desired or desired location. Various means of positioning tip 301 are used to place the cutting zone in the appropriate area to relay the signal flowing through nerve 101 .

[0105] device operation

[0106] [00105] There are many possible electrode diameter and tip shape combinations. The "new" probes perform various functions such as stimulation, optical and electronic guidance, drug delivery, sampling and controlled cutting. The bipolar elect...

Abstract

An electrosurgical probe including a probe body which defines a longitudinal probe axis. The electrosurgical probe also includes a first and second conductive electrode, each disposed along the probe axis. The surface area of the first conductive electrode is greater of the surface area of the second conductive electrode. The ratio of the surface area of the first conductive electrode to the surface area of the second conductive electrode may be adjustable. Another aspect of the present invention is an electrosurgical probe having a probe body which defines a single longitudinal probe axis. The electrosurgical probe of this aspect of the invention further includes more than two electrodes operatively disposed at separate and distinct positions along the axis of the probe body. The electrodes may be selectively connected to one of or a combination of a stimulation energy source, an ablation energy source or a ground for either energy source. Another aspect of the present invention is a method of placing an electrosurgical probe such as described above for specific ablation procedures.

Description

technical field [0001] [0001] The present invention relates to methods and devices used in the field of minimally invasive surgery (MIS) for interrupting the flow of signals through nerves. These nerves can be rendered incapable of conducting signals temporarily (hours, days, or weeks) or permanently (months or years). One embodiment of the present invention includes a single puncture system featuring the ability to create a zone of nerve destruction, inhibition and cutting. Background technique [0002] [0002] The human nervous system is used to send and receive signals. The pathways taken by neural signals conduct sensory information such as pain, heat, cold, and touch and command signals that result in movement (eg, muscle contraction). [0003] [0003] Extraneous, unwanted or abnormal signals are often generated (or transmitted) along nervous system pathways. Examples include, but are not limited to, compression of secondary nerves in the back causing extreme back pain...
