Cutting devices including a probe or needle useful for resecting nerve and soft tissue via a minimally invasive procedure to alleviate pain are provided. The cutting devices include an internal passage and a distal end that can have a tip and a groove positioned near the tip or at the tip at the distal end of the probe. The probe or needle can have an electrically insulated layer or coating adjacent to and exposing the groove which is configured to receive pulsed plasma mediated radio frequency discharges adapted for cutting nerve and/or soft tissue. The internal passage of the probe or needle can be configured to engage a vacuum for suction of the cut nerve and/or tissue, or separate passage for injection of fluids, sealants or cements. Methods for cutting nerve and/or soft tissue utilizing the cutting devices are also provided. |
