Intended Use

The Diamondback 360® Peripheral Orbital Atherectomy System is a percutaneous orbital atherectomy system indicated for use as therapy in patients with occlusive atherosclerotic disease in peripheral arteries and who are acceptable candidates for percutaneous transluminal atherectomy.

The OAS supports removal of stenotic material from artificial arteriovenous dialysis fistulae (AV shunt). The system is a percutaneous orbital atherectorny system indicated as a therapy in patients with occluded hemodialysis grafts who are acceptable candidates for percutaneous transluminal angioplasty.

The Stealth 360® Peripheral Orbital Atherectomy System is a percutaneous orbital atherectomy system indicated for use as therapy in patients with occlusive atherosclerotic disease in peripheral arteries and who are acceptable candidates for percutaneous transluminal atherectomy.

The OAS supports removal of stenotic material from artificial arteriovenous dialysis fistulae (AV shunt). The system is a percutaneous orbital atherectorny system indicated as a therapy in patients with occluded hemodialysis grafts who are acceptable candidates for percutaneous transluminal angioplasty.

Device Description

The Diamondback 360 and Stealth 360 Peripheral Orbital Atherectomy Systems (OAS) are designed to remove or reduce occlusive material and restore luminal patency by using an orbiting, diamond-coated, eccentrically mounted crown.

The OAS consists of the following main components:

  1. Reusable Saline Pump (provided non-sterile)
  2. Single-use Orbital Atherectomy Device (OAD) (provided sterile)
  3. Single-use Atherectomy lubricant (provided sterile)
  4. Single-use Atherectomy guide wire (provided sterile)

Mechanism of Action
The Diamondback and Stealth OAS mechanism of action is defined by:
• Centrifugal force
• Orbital rotation
• Differential sanding
• Bi-directional sanding
The rapidly rotating eccentric crown creates a centrifugal force that presses the diamond-coated crown against the calcified plaque. With each pass of the crown, plaque is reduced and the diameter of the orbit increases.

AI/ML Overview

The provided text is an FDA 510(k) summary for a medical device (Diamondback 360® Peripheral Orbital Atherectomy System, Stealth 360® Peripheral Orbital Atherectomy System). It details the device's purpose, components, mechanism of action, and comparison to a predicate device.

However, the document does not contain information about the acceptance criteria and the study proving the device meets those criteria in the context of an AI/ML-driven device. The content focuses on the substantial equivalence of a modified atherectomy system to a previously cleared predicate device, based on functional and safety testing of the hardware components (e.g., motor, bearings, grease).

Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria for an AI/ML device, as this information is not present in the provided text. The questions posed (e.g., sample size for test set, number of experts for ground truth, MRMC study, standalone performance) are specific to the evaluation of AI/ML algorithms, which is not the subject of this 510(k) summary.
