DEVICE: COOLIEF* Cooled Radiofrequency Kit (00193493442003)

A collection of various sterile neurosurgical instruments, dressings and the necessary materials used to perform a neurosurgical procedure. It does not contain pharmaceuticals. This is a single-use device.

A hand-held surgical instrument intended to be percutaneously introduced via a dedicated cannula [under external image guidance or using electrical stimulation for nerve location] to deliver radio-frequency current, in a monopolar configuration, from a system generator directly to peripheral nerve tissues to coagulate/ablate them for the treatment of pain. It includes a distal monopolar electrode which may include temperature-sensing elements; the introduction cannula or a tubing set to allow fluid cooling of the electrode may be included. This is a single-use device.

A rigid tube designed to provide percutaneous (through the skin) tissue access through its lumen for an electrosurgical probe during radio-frequency (RF) ablation procedures (typically of peripheral nerves to treat chronic pain) and for the injection/aspiration of fluids (e.g., local anaesthetic agents). It is made of metal (e.g., stainless steel), covered in insulation except for its distal tip, and includes a plastic hub; it is available in a variety of diameters and distal tip lengths/configurations. This is a single-use device.
