The device description focuses on mechanical components and materials, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes.
The device is intended to disrupt fibrin sheath formation on vascular access catheters to restore functional patency, which is a direct therapeutic action to improve the function of the catheters.
No
The device is intended to disrupt fibrin sheath formation and restore patency of vascular access catheters, which is a therapeutic function, not a diagnostic one.
No
The device description clearly details a physical, tri-axial catheter assembly made of various materials (Polyimid/PTFF, nylon, Nitinol, gold) with an injection molded plastic hand assembly. This is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "disrupt fibrin sheath formation on both the external and internal surface of vascular access catheters, thus restoring functional patency." This describes a therapeutic or interventional procedure performed directly on a medical device (the catheter) within the patient's body.
- Device Description: The description details a mechanical device designed to physically interact with the catheter to remove build-up. It involves a delivery catheter, guide structure, and stripping coil.
- Lack of Diagnostic Purpose: There is no mention of the device being used to analyze samples (blood, tissue, etc.) or to provide information for the diagnosis of a disease or condition.
- Anatomical Site: The anatomical site is "vascular access catheters," which are implanted medical devices, not biological samples.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Fibrex™ Catheter Patency Device does not fit this definition. It is a device used to restore the function of another medical device.

Device Description
The Fibrex™ Catheter Patcncy Device is a tri-axial delivery catheter assembly comprised of an outer catheter storing an inner guide structure and an inner stripping coil. The inner guide structure is for directing and guiding the stripping coil through the catheter to the free end of the catheter and back up around the exterior surface of the vascular catheter. The stripping coil is formed of a shape memory or super-elastic material, wherein the stripping coil is preformed to assume a helical shape wrapping about the outer surface of the vascular catheter in a manner providing for the stripping of build-up from the outer surface of the vascular catheter when the stripping coil is moved relative to the vascular catheter.
The tri-axial delivery catheter assembly is attached to an injection molded plastic hand assembly that controls the movement of the guide catheter and subsequent insertion of the stripping coil. The delivery catheter assembly is adapted for selectively coupling to a luer connector secured to the venous lumen of a traditional vascular catheter.
The outer catheter of the Fibrex™ device is made from a biocompatible Polyimid/PTFF. composite. The inner dual lumen tube is made from nylon. A Nitinol wire is housed in one lumen of the guide curve catheter to provide directional memory for the actuation and operation of the Nitinol stripping coil . Both the outer catheter and the guide catheter contain distal marking bands made from gold.
