Diamondback 360® Coronary Orbital Atherectomy System

Diamondback 360 Coronary Orbital Atherectomy System

TREAT WITH CONFIDENCE – Be Calculated™ with the proven Diamondback 360 Orbital Atherectomy System.

Take a calculated approach when treating severely calcified coronary lesions – gaining greater confidence in your patients’ Percutaneous Coronary Intervention (PCI) outcomes.

Diamondback 360 Coronary Orbital Atherectomy System’s (OAS) 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 target lesion revascularization (TLR) rate of 3.4% in drug eluting stent (DES) subset* at one year.8

*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 a First-line Approach for Severe Arterial Calcium

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

GlideAssist® Mode

GlideAssist enables the crown to spin at a slow speed (5K RPM), reducing friction in the system to*:

  • Facilitate tracking of the device
  • Provide easier removal of the device
  • Allow smoother repositioning of the ViperWire Advance® during procedures

Classic Crown

The Diamondback 360 Coronary OAS utilizes a 1.25 mm eccentrically mounted diamond-coated crown:

  • Reduces severe calcium and allows the healthy tissue to flex away
  • Provides bi-directional sanding
  • Creates minuscule particulates (most smaller than a red blood cell51)

GlideAssist is the innovative solution that allows for tracking, easier removal and smoother repositioning of the device – especially in challenging anatomies.

ViperWire Advance Coronary Guide Wire

ViperWire Advance Coronary Guide Wire was designed to be easy to use and to provide the tactile feedback to increase physicians’ ability to navigate the wire throughout the vessel.

Customize treatment with two guide wire options: The ViperWire Advance stainless steel guide wire or ViperWire Advance with Flex Tip nitinol guide wire, with a stainless steel support coil which allows the tip to be shaped as needed.


ViperWire Advance with Flex Tip’s flexible nitinol body was designed to reduce wire bias and kink resistance during coronary procedures. The stainless steel support coil provides a shapeable tip for navigation in multi-vessel coronary lesions.

  • Material/Body Type: Nitinol/flexible/kink resistance
  • Tip/Core Diameter: .014/.012
  • Tip Load/Type: 1.0g floppy
  • Tip Shapeability: Stainless steel support coil allows tip to be shaped as needed

Harmonized OAS Pump Diamondback 360

OAS Pump

The OAS Pump keeps pace with the evolving Cath Lab environment, focusing on safety, simple set up and ease of use. It mounts directly onto an intravenous pole and provides power and the pumping mechanism for the Diamondback 360 System.

ViperSlide® Lubricant

ViperSlide is an exclusive lubricant for use with CSI® Orbital Atherectomy Systems. ViperSlide increases the lubricity, therefore reducing friction between the device and the ViperWire Advance Guide Wire.

Be Calculated with the Diamondback 360 has a unique dual Mechanism of Action designed:

  • With a particulate size of 2 µm—smaller than a capillary vessel—and continuous blood flow during orbit, Diamondback 360 may reduce risk of slow flow and no reflow.51,52
  • A single 6 Fr 1.25 mm crown treats vessels 2.5 mm to 4.0 mm through a 6 Fr access.53
  • The diamond-coated crown sands intimal calcium into particulate with an average size of approximately 2 μm—which is smaller than a capillary vessel.10
  • The pulsatile impact of the crown against deep plaque can create microfractures that modify deep calcium.51,52,61,62*
