Patient Stories

Helping you get your patients back to what matters


The Diamondback 360® Peripheral Orbital Atherectomy Systems (OAS) deliver versatile, low-profile devices that give you more access site options. In our clinical studies with real-world patients and the most challenging lesions, OAS has demonstrated successful lesion modification while maintaining low complication rates.




The Diamondback 360® Coronary Orbital Atherectomy System (OAS) is the only device indicated to treat severely calcified coronary lesions. Orbital Atherectomy enables successful stent deployment, helping to lead to safe and effective percutaneous coronary intervention (PCI) outcomes.





See the Devices in Action

How it works:

The unique mechanism of action uses a combination of centrifugal force and differential sanding to treat arterial calcium.  The Diamondback 360 MOA is designed to treat 360° of the vessel as it sands away the calcium, while allowing for continuous flow of blood and saline during orbit.


Commitment to Clinical & Economic Rigor


Physicians and payers are increasingly seeking clinical and economic evidence to allow them to make decisions regarding optimal treatment of patients. We are focused on conducting and collecting clinical and economic evidence to demonstrate the advantages of OAS in treating complex disease states such as PAD and CAD.

We believe that the clinical data and cost-effectiveness of our OAS technology will help drive physician utilization of the OAS and sustain ongoing reimbursement coverage for our devices.11

    Click HERE TO SEE THE LIBERTY 360° Study 3-Year Data LIBERTY is the largest, contemporary, real-world experience study to evaluate procedural and long-term clinical outcomes of endovascular device interventions in patients with symptomatic lower extremity peripheral artery disease (PAD). Study Design1   Prospective, observational, multicenter study that includes any FDA-cleared or approved technology to treat claudication and critical limb ischemia (CLI). 1204 patients enrolled at 51 sites and were followed for up to 5 years. 4 core labs used for independent analysis. Key endpoints: Procedural and lesion success, Major Adverse Events (MAEs), Duplex Ultrasound (DUS), Quality of Life (QoL), and Six-Minute Walk Test (6MWT). Key inclusion criteria: Rutherford classification (RC) 2 to 6, target lesion located within or extending into 10 cm above the medial epicondyle to the digital arteries (distal 1/3 of the SFA and below), and at least one lesion that can be treated with an endovascular device.   Conclusion Peripheral vascular intervention (PVI) may be a reasonable treatment option across all Rutherford classes with durable results lasting to 3-years.2 High freedom from major amputation TVR/TLR at 3 years across all Rutherford classes2 In the OAS sub-analysis, freedom from major amputation TVR/TLV rates at 3 years were even higher than in the full patient cohort2 Improved Quality of Life by 30 days and maintained to 3 years across all Rutherford classes High long-term patency rates through 2 years in RC2-33 Improvement in mean number of wounds from 30 days to 2 years in RC4-63   1.

  • ECLIPSE
    anemptytextlline
    ECLIPSE: Evaluation of Treatment Strategies for Severe CaLcIfic Coronary Arteries: Orbital Atherectomy vs. Conventional Angioplasty Technique Prior to Implantation of Drug Eluting StEnts   Purpose of the ECLIPSE Trial Severely calcified coronary lesions represent 6-20%1,2 of the total Percutaneous Coronary Interventions (PCI) market (880K annual procedures). Coronary atherectomy represents < 5%3,4 of the PCI market and is not currently classified as the Standard of Care (SOC) in treatment guidelines. ECLIPSE is a prospective, randomized one to one (1:1), multi-center trial designed to evaluate vessel preparation with the Diamondback 360® Coronary Orbital Atherectomy System (OAS) Classic Crown compared to conventional balloon angioplasty technique prior to stent implantation for the treatment of severely calcified coronary artery lesions.
