Redefining minimally invasive

4 Fr. sheath compatibility

  • Smaller sheaths are associated with fewer bleeding complications and reduced closure time1,2,3

Creating tibiopedal access solutions with 60cm devices

Expanding the endovascular interventional market and providing more treatment options

  • 4 Fr. sheath compatibility
  • Shorter, 60cm shaft for more convenient tibiopedal access

OAS Outperforms Balloon Angioplasty in Below-the-Knee (BTK) Lesions5

Excellent acute performance in patients with critical limb ischemia



Randomized, multicenter, prospective BTK study comparing OAS to balloon angioplasty alone in calcified lesions

Orbital Atherectomy System outperforms balloon angioplasty in BTK lesions enabling:

  • Lower balloon inflation pressure
  • Lower bail-out stent rate
  • Statistically significant difference in freedom from major adverse events* at 12 months

*Major adverse events: major amputation (above-the-ankle), death and TLR/TVR



These Diamondback 360® Systems are the first in the low profile family that leverage the Stealth 360® System’s OAS technology and sleek electric handle design.

Caution: Federal law (USA) restricts this device to sale by, or on the order of, a physician. The CSI Orbital Atherectomy System is a percutaneous orbital atherectomy system indicated for use as therapy in patients with occlusive atherosclerotic disease in peripheral arteries and stenotic material from artificial arteriovenous dialysis fistulae. Contraindications for the system include use in coronary arteries, bypass grafts, stents, or where thrombus or dissections are present. Although the incidence of adverse events is rare, potential events that can occur with atherectomy include: pain, hypotension, CVA/TIA, death, dissection, perforation, distal embolization, thrombus formation, hematuria, abrupt or acute vessel closure, or arterial spasm.
