The device description and performance studies focus on mechanical and electrical components and their physical performance, with no mention of AI/ML algorithms or data processing for decision-making or analysis.
Yes
The device is intended for atherectomy and thrombus removal, which directly treats occlusive atherosclerotic disease in peripheral arteries, restoring luminal patency.
No
The device is designed for atherectomy and removal of thrombus, which are therapeutic interventions to treat occlusive disease, not to diagnose it.
No
The device description clearly outlines multiple hardware components, including a drive shaft, burr, power supply, guidewire, infusion assembly, collection receptacle, and guidewire clip. It is a physical medical device used for atherectomy.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside the body (in vitro).
- Device Function: The Revolution Peripheral Atherectomy System is a surgical device used inside the body (in vivo) to physically remove plaque and thrombus from blood vessels. It does not analyze biological samples.
- Intended Use: The intended use clearly describes a therapeutic procedure performed directly on the patient's vasculature, not a diagnostic test on a sample.
- Device Description: The description details a mechanical system with a rotating burr for ablation and removal of material from within the body.
- Performance Studies: The performance studies focus on the mechanical and biological interactions of the device within the body (e.g., plaque removal efficiency, embolization analysis, biocompatibility), not on the accuracy of diagnostic measurements from samples.
Therefore, based on the provided information, the Revolution Peripheral Atherectomy System is a therapeutic medical device, not an In Vitro Diagnostic device.

Device Description
The Revolution Peripheral Atherectomy System is sterile, single-use device designed for atherectomy of the peripheral vasculature and to break apart and remove thrombus from the peripheral arteries in patients with occlusive atherosclerotic disease.
The Revolution device incorporates a flexible drive shaft designed to track over the Revolution guidewire. Attached to the distal end of the drive shaft is a diamond coated spheroid shaped burr which rotates at high speed to ablate occlusive material and restore luminal patency. Power is derived from a mains source and converted using the reusable power supply. During treatment, the rotating burr ablates material into fine particles. This particulate is conveyed proximally by a mechanical means through the catheter and handle into a collection receptacle that resides outside the patient. The device is available in 145cm, 200cm, and 60cm lengths with burr diameters of 1.33mm, 1.66mm, 2.00mm, and 2.33mm.
The Revolution Peripheral Atherectomy System consists of the following components:
- Single-use Revolution Device (provided sterile)
- Single-use Revolution .014" Guidewire (provided sterile)
- Single-use infusion assembly (provided sterile)
- Single-use collection receptacle (provided sterile)
- Single-use guidewire clip (provided sterile)
- Reusable power supply (provided non-sterile)

Dear Colin Valentis:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

510(k) Summa Per 21 CFR 807.
Technological The proposed Revolution Peripheral Atherectomy System is substantially equivalent to Characteristics the currently marketed Revolution Peripheral Atherectomy System (K191419). The Comparison: subject and predicate devices share the following technological characteristics:
- . Intended Use
- . Fundamental Cutting Mechanism
- Fundamental Scientific Technology .
- Principles of Operation ●
- Conditions of Use ●
- . Sterilization Method
The differences between the subject and predicate device include the addition of several product codes and modifications to the construction and materials of certain components.
Changes in catheter material and drive wire construction were implemented in order to reduce the total stiffness of the system to improve performance in highly tortuous anatomy.
The additional product code offerings include a 2.33mm bit, a 200cm length, and lowprofile sheath options for the 1.66mm and 2.00mm bits which reduces the sheath compatibility to 6F.
