Treat with Confidence

Be Calculated® with the proven Diamondback 360® Orbital Atherectomy System.

Proven Technology

CSI’s innovative and evidence-based solutions perform in complex calcium so physicians can treat with confidence. More than 90,000 patients have been treated with the Diamondback 360® Orbital Atherectomy System. Now enrolling for the ECLIPSE clinical trial. 10, 51-53

Two Effective Forces, One Simple Device

Take control in the cath lab with a single solution that leverages two key forces to safely and effectively reduce coronary calcium. The Diamondback 360 is one device with a patented dual mechanism of action that sands intimal lesions and facilitate fractures medial calcium for optimal stent delivery, expansion and apposition. 51, 61, 10

Orbital Case Studies

Physicians across the country are creating decisive plans for patients using orbital atherectomy over traditional balloon and stent and other methods of atherectomy. See how they’re taking control in the cath lab.

Severely Calcified LAD
Coronary Artery
Samip C. Vasaiwala, MD
A 78-year-old female presented with a history of coronary artery disease, bilateral carotid artery disease and severe calcification, a Diamondback 360® Coronary Orbital Atherectomy System (OAS) was used for the successful revascularization of the left anterior descending coronary artery.

Tight Lesion Treatment
of LAD
Emmanouil S. Brilakis, MD
Dr. Emmanouil Brilakis used orbital atherectomy in the treatment of a severely calcified LAD.

99% Stenosis – Right Proximal
Coronary Artery
Dean M. Ferrera, MD
Dr. Dean M. Ferrera performed a distal RCA revascularization using orbital atherectomy enabling PTCA and multiple stents.

Severely Calcified
Right Coronary Artery
Ramesh Daggubati, MD
Orbital Atherectomy was chosen for this potentially challenging case due to severe calcification in the 62-year-old patient. Using a 6 Fr radial approach, the procedure went smoothly, and no complications occurred.

Multi-Vessel Disease:
LAD and Ramus
Ramesh Daggubati, MD
A calculated treatment plan with Orbital Atherectomy was safely performed on this 60-year-old patient. The quick and easy setup of the system helped to facilitate a complex multi-vessel PCI.
