No
The description focuses on the mechanical components and intended use for delivering substances and facilitating access, with no mention of AI or ML capabilities.
No.
The device is intended for delivering substances to the intradiscal space for diagnostic procedures like provocative discography, accessing the space, and facilitating placement of other components, rather than directly treating a condition or disease.
Yes
The device's intended use explicitly mentions "provocative discography," which is a diagnostic procedure to identify pain sources by injecting a substance into a disc to reproduce a patient's pain.
No
The device description explicitly lists multiple hardware components including catheters, guidewires, needles, stopcocks, syringes, and connectors.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes the device as being used to deliver substances (contrast, anesthetics, saline) into the intradiscal space and to facilitate access to this anatomical site. This is an in vivo procedure, meaning it is performed within a living organism.
- Device Description: The description details components like needles, catheters, guidewires, and a balloon, all designed for physical access and delivery within the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue) outside of the body to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used to perform tests on samples taken from the body, not to directly interact with or deliver substances into the body for therapeutic or diagnostic imaging purposes in the way this device is described.

Intended Use / Indications for Use
The Kyphon Discyphor Catheter System for the Functional Anaesthetic Discography™ Procedure, and its components, are intended for use in delivering either a single dose or continuous administration of radiopaque contrast, local anaesthetics, and/or saline solution to the intradiscal space.
The Kyphon Discyphor Introducer Needle is intended for use to access the area adjacent to the intradiscal space for the purpose of facilitating sequential placement of the Discyphor Spinal Needle, Discyphor Catheter and Discyphor Guidewire into the intradiscal space. The Kyphon Discyphor Introducer Needle is intended to be used only with the Kyphon Discyphor Catheter System.
The Kyphon Discyphor Spinal Needle is intended to access the nucleus of an intervertebral disc for the purpose of nerforming provocative discography and facilitating placement of the Discyphor Catheter and Guidewire into the intradiscal space. The Discyphor Spinal Needle can be used to deliver contrast, antibiotic, and/or saline into an intervertebral disc. The Kyphon Discyphor Spinal Needle is intended to be used only with the Kyphon Discyphor Catheter System.

Device Description
The Discyphor" Catheter System is comprised of a Discyphor" Catheter with guidewire funnel, a Discyphor" Guidewire, a Discyphor" Introducer Needle, a Discyphor" Spinal Needle, a stopcock, syringes, catheter connectors and labels. The Discyphor Catheter is a micro-catheter with a flexible shaft and a balloon located near the distal tip. The metallic Discyphor Guidewire is .009" in diameter and is radiopaque when viewed using fluoroscopy. The stopcock retains pressure within the balloon when used in conjunction with the syringes. The catheter connectors are connected to the lumens of the Discyphor Catheter and provide access to the lumens. Labels are used to identify the solutions used during the procedure or to denote the level at which the Discyphor Catheter has been placed.
The Discyphor Introducer Needle is designed specifically for use with the Discyphor Catheter System. The Discyphor Introducer Needle is stainless steel with a removable stainless steel stylet. The Discyphor Catheter is delivered through the Discyphor Introducer Needle and is tracked over the Discyphor Guidewire.
The Discyphor" Spinal Needle is a standard stainless steel needle with a removable stainless steel stylet. The hubs of the needle and stylet are comprised of polymer.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
In vitro testing was conducted on the materials to evaluate bending stiffness, peak axial strength, fracture and kink resistance. In addition laboratory physician preference testing was conducted. Biocompatibility testing conducted on the Discyphor Catheter System and Guidewire assembly demonstrates that the materials are acceptable for the intended use. The results of testing demonstrate that the guidewire materials are safe and effective for the intended use.

Dear Ms. Domecus:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
