First Postmarket Cases Performed Using Extended-Length Diamondback 360 for Radial PAD Atherectomy

February 14, 2018—Cardiovascular Systems, Inc. (CSI) announced that the first radial access cases were performed using its US Food and Drug Administration–cleared extended-length Diamondback 360 peripheral orbital atherectomy system (OAS). The cases were led by Mahir Elder, MD, at Detroit Medical Center Heart Hospital and Ian Cawich, MD, and Vasili Lendel, MD, at Arkansas Heart Hospital.

The 5-F radial access Diamondback 360 sizes are currently available via a limited market rollout, with full market launch expected in CSI's fiscal year 2019. Current crown and length combinations include 1.25-mm-diameter solid crown, 200-cm length; 1.50-mm-diameter solid crown, 200-cm length; and 1.75-mm-diameter solid crown, 180-cm length.

In the company's announcement, the treating physicians discussed the advantages of radial access in certain peripheral artery disease (PAD) cases.

Dr. Elder pointed to better patient experience, including faster ambulation and discharge versus femoral access.

“From a physician’s perspective, radial access is a viable alternative that allows us to minimize bleeding and avoid commonly diseased femoral arteries," added Dr. Cawich. "Additionally, it allows for both bilateral diagnostics and interventions while also eliminating the need for femoral closure devices. The result for patients is a far less invasive procedure.”

Dr. Lendel noted the recent rise and well-documented benefits of radial access in percutaneous coronary interventions. "Now, I’m excited that new devices like CSI’s extended-length OAS are enabling me to bring the benefits of radial access to another patient population in those undergoing peripheral vascular interventions,” he said.

Earlier this year, CSI announced two partnerships aimed at expanding its peripheral and coronary interventional portfolios.
