DEVICE: NeuroTherm™ (05415067026576)

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.

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 dispersive conductor intended to be fastened to a patient and connected to an electrosurgical/radio-frequency ablation system generator, to allow return of electrical current from the patient to the generator during an electrosurgical procedure. It has a large surface area and is fastened to the patient's body typically where the greatest surface area can be covered in closest proximity to the surgical site. It will typically be designed with permanently attached leads. This is a single-use device.
