Intended Use
The Phoenix® Atherectomy System is intended for use in atherectomy of the peripheral vasculature. It is not intended for use in coronary, carotid, iliac or renal vasculature.
Device Description
The AtheroMed Phoenix Atherectomy System is a sterile, single-use device designed for atherectomy of the peripheral vasculature. The Phoenix Atherectomy System has two main components: the Phoenix Catheter and the Phoenix Handle. The Phoenix Catheter is a flexible, over-the-wire (OTW), front-cutting Catheter that continuously captures and clears debulked plaque proximally through the Catheter and Handle into a collection reservoir that resides outside the patient. For use, the Phoenix Catheter is inserted into the Phoenix Handle incorporates a self-contained battery-powered motor designed to drive and rotate the cutter of the Phoenix Atherectomy Catheter at its specified rotational speed. The device is activated by an ON/OFF slider switch on the top of the Handle. An optional Wire Support Clip can also be used to clip a guidewire torque device in a fixed position relative to the Handle. The Catheter, Handle, and Wire Support Clip are each packaged separately as sterile, single-use components of the Phoenix Atherectomy System. There are three different models of the Phoenix Catheter. Two Phoenix Catheter models track directly over the guidewire with no tip deflection capability. These models are available in 1.8mm and 2.2mm tip diameter sizes. A third, 2.4mm tip diameter model has a Catheter tip design that can be deflected and rotated by the user so that the cutter can eccentrically debulk to a larger diameter than the Catheter's 2.4mm distal cutter. The controls for deflection and rotation are housed in the Phoenix Handle when the Catheter is inserted into the Handle. All three Phoenix Catheter models are compatible with commercially available 0.014" exchange length (260cm or greater) guidewires, and all use the same Phoenix Handle. This 510(k) includes modifications to the cutter and distal assembly of the 1.8mm and 2.2mm tip diameter Phoenix Catheter models, as well as modifications to the Catheter and proximal chassis design, to further optimize the device design and manufacturability of the device. Table 9-1 summarizes the subject modifications relative to the predicate device. Additionally, the Phoenix Guidewire has been added as a compatible guidewire in the product labeling.

No
The description focuses on mechanical components, a battery-powered motor, and user-controlled features. There is no mention of AI, ML, image processing, or data analysis for decision-making or control.

Yes.
The device is used for atherectomy, which is a medical procedure to remove plaque from arteries, fitting the definition of a therapeutic intervention.

No

The device description clearly states its purpose is for "atherectomy of the peripheral vasculature," which is a treatment procedure for removing plaque, not for diagnosing a condition.

No

The device description clearly outlines physical components like a catheter, handle with a battery-powered motor, and a collection reservoir, indicating it is a hardware-based medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is "atherectomy of the peripheral vasculature." This is a surgical procedure performed directly on the patient's blood vessels to remove plaque.
  • Device Description: The device is a mechanical system (catheter and handle) designed to physically remove plaque from within the body.
  • Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, or tissue) outside the body to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis of specimens.

The device is clearly an interventional medical device used for a therapeutic procedure within the patient's body.
