Coronary Diamondback 360® Orbital Atherectomy System – Beta

Gain greater confidence in your patients’ PCI outcomes when treating severely calcified coronary lesions.

Diamondback 360® Coronary OAS’s unique mechanism of action uses a patented combination of centrifugal force and differential sanding to safely and simply reduce arterial calcium, enabling successful stent delivery.

In the ORBIT II pivotal trial, the Diamondback 360® Coronary OAS demonstrated durable results with low TLR rate of 3.4% in DES subset* at one year.

*Subjects with DES only (N=389/443)

At CSI, we are a culture of innovation, driven by the understanding that smart design changes, no matter how small, can make a big difference at a critical moment – a difference that may make things simpler, deliver better outcomes or even save a life. We observe carefully, listen closely and collaborate extensively, seeking opportunities to help interventionalists do their jobs more easily and more effectively – all with the goal of improving patient care.

OAS is the Solution for Arterial Calcium

Coronary calcium tends to be underestimated. Calcium considered mild or moderate by angiography may actually be severe if advanced imaging such as IVUS or OCT are used.44  Moderate to severe arterial calcium is present in nearly 40% of patients who undergo a Percutaneous Coronary Intervention (PCI).1


  • Diabetes
  • Chronic Kidney Disease
  • Advanced Age (>65 y/o)
  • Smoker
  • Dyslipidemia
  • Hypertension
  • Prior CABG
  • Known PAD/CAD


  • Prone to dissection during balloon angioplasty or pre-dilatation
  • Difficult to fully dilate the balloon
  • May prevent adequate stent expansion and apposition
  • May prevent stent delivery

The Diamondback 360® has a unique Mechanism of Action designed to:

  • Treat 360° of the vessel wall
  • Provide continuous flow of blood and saline during orbit minimizing thermal injury
  • Treat 2-4 mm* vessels with a single crown through a 6 fr guide enabling radial access
*Based on minimum reference vessel diameter as determined by orbit testing in a carbon block model
