The device description and performance studies focus on mechanical and physical properties, with no mention of AI/ML algorithms or data processing for decision-making or analysis.
Yes
The device is described as an "atherectomy device" and is intended "to break up and remove thrombus from upper and lower extremity peripheral arteries," which are therapeutic actions.
No
The device is described as an "atherectomy device" used to "break up and remove thrombus from upper and lower extremity peripheral arteries." Its function is therapeutic, not diagnostic.
No
The device description clearly outlines multiple hardware components including a catheter, guidewire, collecting bag, drape, control unit, motor, and foot switch. The performance studies also detail testing related to the physical properties and function of these hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for use as an atherectomy device to break up and remove thrombus from peripheral arteries. This is a therapeutic procedure performed in vivo (within the body), not a diagnostic test performed in vitro (outside the body) on biological samples.
- Device Description: The description details a mechanical system with a catheter, rotating head, and aspiration mechanism designed to physically interact with and remove material from within blood vessels. This is consistent with a surgical or interventional device, not a diagnostic one.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (like blood, urine, or tissue) or providing diagnostic information based on such analysis. The device's function is purely mechanical removal of material.
Therefore, the Straub Endovascular System is a therapeutic medical device, not an In Vitro Diagnostic device.

Device Description
The Straub Endovascular System consists of:
- Rotarex®S catheter set which includes a Rotarex®S catheter, guidewire, collecting bag and drape. ● All are provided sterile and are for single use
- . Drive System, consisting of the Control Unit, Motor and Foot switch. The Drive System serves to drive and control the rotational catheters.
Rotarex S is an over-the-wire, percutaneous catheter. The catheter consists of a flexible braided shaft, a rotating head, and a rotating helix which runs the length of the catheter. A lumen for the passage of the supplied guidewire runs the entire length of the helix and through the head of the catheter. The catheter head is made up of two overlying metal cylinders, with two side openings.
The outer cylinder is connected to the rotating helix, and the inner cylinder to the catheter shaft. The helix and the catheter head rotate at approximately 40.000-60.000 rpm depending on the model, by means of a gear box in the catheter housing and a motor contained within the catheter handle driven by the Drive System. The rotating outer cylinder is fitted with facets at its foremost tip, which when rotating, serve to abrade occluding material lying in front of it. Concomitantly, the rotation of the catheter head creates a vortex in the blood which assists to further erode occluding material from the vessel lumen. The detached material is aspirated into the side openings of the overlying cylinders where it is further broken down within the head and then carried through the inner lumen into a collecting bag outside of the body.
