Intended Use

The Functional Anaesthetic Discography (FAD) Catheter System is intended for use in delivering either a single dose or continuous administration of a radiopague contrast, local anaesthetics, and/or saline solution to the intradiscal space. The FAD Introducer Needle is intended for use to access the area adjacent to the intradiscal space for the purpose of facilitating placement of the FAD Catheter and Guidewire into the intradiscal space.

Device Story

The FAD System is a medical device kit comprising a micro-catheter and an introducer needle used to access the intradiscal space. The system allows for the delivery of radiopaque contrast, local anesthetics, or saline solutions. The catheter features a flexible polymer shaft with an expandable anchor mechanism, controlled via a dedicated lumen, to secure the catheter in place during fluid administration. Two radiopaque markers facilitate radiographic positioning. The introducer needle, made of stainless steel with a stylet, provides the initial access path for the guidewire and catheter. The device is intended for use by clinicians in a clinical setting. By enabling precise placement and anchoring of the catheter, the system facilitates targeted delivery of diagnostic or therapeutic agents to the intradiscal space, potentially aiding in the diagnosis or management of spinal conditions.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

System consists of a flexible polymer micro-catheter with an expandable anchor mechanism and a stainless steel introducer needle with stylet. Includes radiopaque markers for positioning. Accessories include guidewire, syringes, and Touhy-Borst adapters. Non-electronic, mechanical device.

Indications for Use

Indicated for patients requiring delivery of radiopaque contrast, local anesthetics, or saline to the intradiscal space. Used to access the intradiscal space via an introducer needle for catheter and guidewire placement.

Regulatory Classification

Identification

An anesthesia conduction needle is a device used to inject local anesthetics into a patient to provide regional anesthesia.
