Radio-frequency ablation system probe cannula, reusable
Definition
A rigid tube designed to provide body tissue access through its lumen for a radio-frequency (RF) probe during 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 reusable device intended to be sterilized prior to use.
