For more information about the new Diamondback 360°™ Orbital Atherectomy System from CSI, please contact your local CSI representative or call customer service at 1.877.CSI.0360
The Diamondback 360° System uses the principle of centrifugal force. As crown rotation increases, centrifugal force presses the eccentrically mounted, diamond-coated crown against the stenotic lesion, removing a thin layer of plaque. The increasing crown orbit creates a larger lumen — minimizing procedure time and expense of catheter upsizing.
Additional benefits of the orbiting motion include:
Removing plaque while minimizing the potential for stress or injury to the media layer, and reducing the risk of barotrauma.
The use of a 6 French introducer sheath
Focus on Speed
1 to 1.75 ratio minimizes device exchanges
Single-insertion convenience
Average procedure run time of 3 minutes*
Safety in Motion
Intelligent differential sanding
The "differential sanding" feature of the Diamondback 360° System minimizes the incidence of arterial
wall perforations and dissections.
Diseased tissue provides resistance and allows grit to "sand" the plaque.
Elastic media tissue "gives" and may not be affected by diamond grit.
Minimized risk of vascular bed overload
In 33 CSI particulate experiments over the past 3 years performed in carbon blocks,
porcine and cadaver models:
The average particulate was 2.24 microns with 99% confidence
93.14% of all particulate was smaller than 8.2 microns the size of a red blood cell
*Particulate is 99.1% smaller then the average capillary
