diamondback 360 peripheral orbital atherectomy system

Cardiovascular Systems

Summary: The Diamondback 360 Peripheral Orbital Atherectomy System is a device used for plaque modification in peripheral artery disease. It is primarily used to facilitate percutaneous revascularization. Key evidence highlights its use in critical limb ischemia and optimizing TAVR access.

FDA Clearance Information

Pathway 510K
Number K150732 ↗
Decision Date April 13, 2015
Product Code MCW
Device Class Class 2
Evidence 19 studies

The Diamondback 360 Peripheral Orbital Atherectomy System was cleared by the FDA through the 510(k) pathway on April 13, 2015. It is manufactured by Cardiovascular Systems and is classified as a Class 2 device under product code MCW.

What It Is

The Diamondback 360 Peripheral Orbital Atherectomy System is a minimally invasive device designed to remove plaque from peripheral arteries. It uses orbital motion to sand away calcified plaque, facilitating improved blood flow and enabling subsequent interventions such as angioplasty.

Clinical Applications

This device is commonly used in patients with peripheral artery disease, particularly those with heavily calcified lesions. It is also employed in critical limb ischemia and to optimize access for trans-catheter aortic valve replacement (TAVR) procedures.

Evidence Summary

The available literature includes a mix of retrospective analyses, observational studies, and case series, with a total of 7 studies published between 2015 and 2020. These studies explore various clinical applications and economic impacts of the device.

Reported Outcomes

Published studies report that the Diamondback 360 Peripheral Orbital Atherectomy System is effective in modifying calcified plaques, facilitating successful revascularization. It has been shown to improve access for TAVR procedures and reduce the risk of vessel injury in critical limb ischemia.

Safety Profile

Reported complications include guidewire fractures during the procedure, as noted in a review of the MAUDE database. Other potential adverse events are related to vascular access and procedural risks inherent to atherectomy.

Evidence Limitations

The evidence is limited by the retrospective nature of many studies and the lack of large-scale randomized controlled trials. Further research is needed to systematically evaluate long-term outcomes and safety in diverse patient populations.
