Intended Use
Stereotaxis Cronus® Guide Wires are intended to introduce and position over-the-wire catheters and other over-the-wire therapeutic devices within the coronary and peripheral vasculature during PTCA or other intravascular interventional procedures.
Device Description
The Stereotaxis Cronus Guide Wires are steerable guide wires that have a nominal diameter of 0.014 in/ 0.36mm and nominal lengths from 180 cm to 300 cm. The guide wires are designed only for use in conjunction with the Stereotaxis Magnetic Navigation System. The wire is configured with a tapered distal tip and an embedded magnet, which is used for navigating the wire through the vasculature. A hydrophilic coating covers the distal portion of the wires, and a PTFE coating covers the proximal end of the wires. This device is sterilized with 100% ethylene oxide. The Cronus Guide Wires are conventional 0.014" hydrophilically coated endovascular guide wire modified to accommodate magnetic actuation and control. It is designed to navigate within the vasculature to deliver a suitable catheter or interventional device to a desired site. The finished length of the guide wire is 180cm to 300cm. A taper runs proximal to the distal tip. The pushable shaft is a continuous wire that allows axial force, applied at the proximal end, to be transmitted to the tip of the guide wire. The guide wire is used with an introducer sheath to access the human vasculature.

No
The description focuses on the physical characteristics and magnetic navigation capabilities of the guide wire, with no mention of AI or ML.

No
The device, Stereotaxis Cronus Guide Wires, is described as a steerable guide wire designed to introduce and position other over-the-wire catheters and therapeutic devices. It is explicitly stated that it is used to "deliver a suitable catheter or interventional device to a desired site," indicating it is a delivery mechanism for therapy, not a therapeutic device itself.

No

Explanation: The device is a guide wire intended to introduce and position other therapeutic devices within the vasculature. It is not described as providing any diagnostic information about the patient's condition.

No

The device description clearly details a physical guide wire with specific dimensions, materials (hydrophilic coating, PTFE coating), and an embedded magnet. It is a tangible hardware device.

Based on the provided information, the Stereotaxis Cronus® Guide Wire is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use is to "introduce and position over-the-wire catheters and other over-the-wire therapeutic devices within the coronary and peripheral vasculature during PTCA or other intravascular interventional procedures." This describes a device used within the body for a therapeutic or interventional purpose.
  • Device Description: The description details a physical guide wire designed to be navigated through the vasculature. It's a tool for delivering other devices.
  • Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Cronus Guide Wire does not interact with or analyze such specimens.

Therefore, the Stereotaxis Cronus® Guide Wire is a medical device used in vivo (within the body) for interventional procedures, not an IVD.

Intended Use / Indications for Use

The Stereotaxis Cronus Guide Wires are intended to introduce and position over-the-wire catheters and other over-the-wire therapeutic devices within the coronary and peripheral vasculature during PTCA or other intravascular interventional procedures.

Dear Mr. Rauvola:

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
