ST. PAUL, Minn.--(BUSINESS WIRE)--Cardiovascular Systems, Inc. (CSI®) (NASDAQ: CSII), a medical device company developing and commercializing innovative interventional treatment systems for patients with peripheral and coronary artery disease, announced today that Japan’s Ministry of Health, Labor and Welfare (MHLW) has approved the Diamondback 360® Coronary Orbital Atherectomy System (OAS) with Classic Crown (Classic Crown) and ViperWire Advance® Coronary Guidewire FlexTip (FlexTip).
Classic Crown is the market-leading coronary atherectomy device in the United States. Classic Crown utilizes a 1.25mm eccentrically mounted diamond-coated crown and a patented combination of centrifugal force and differential sanding to safely modify arterial calcium. This device now features GlideAssist®, which allows for tracking, easier removal and smoother repositioning of the device – particularly in challenging anatomies.
FlexTip is a unique new atherectomy guidewire with a nitinol core and shapeable stainless-steel tip for increased flexibility and kink-resistance, improved navigation, and reduced guidewire bias in complex coronary vessels. Classic Crown can also be used with ViperWire Advance® Coronary Guidewire FlexTip.
Dr. Shigero Saito, of Shonan Kamakura General Hospital, Kamakura City, Japan and National Principal Investigator of CSI’s COAST trial, who treated the first patient with both of the newly approved products, said, “Using the new ViperWire Advance FlexTip combined with the GlideAssist feature on Classic Crown allowed me to easily track the OAS device through tortuous coronary vessels and effectively modify a calcified lesion facilitating stent deployment.”
Scott Ward, Chairman, President and Chief Executive Officer of CSI, concluded, “We are excited to introduce the Classic Crown and FlexTip in Japan – the first market with an opportunity to use these two products together. Ten to 20 percent of the 280,000 Japanese patients who undergo percutaneous coronary interventions, or PCIs, each year have severely calcified coronary lesions. Multiple studies have shown that calcium is associated with poor PCI outcomes. Orbital atherectomy modifies calcific plaque to improve PCI results. Physicians in Japan may now consider our Classic Crown or Micro Crown to provide durable and cost-effective results for this large and underserved patient population.”
CSI received MHLW approval for the Diamondback 360® Coronary OAS Micro Crown in March 2017 and reimbursement approval in February 2018. In November 2016, CSI announced that Medikit, Co., Ltd. signed an exclusive distribution agreement to sell its coronary and peripheral OAS in Japan.

Diamondback 360® Coronary Orbital Atherectomy Systems
Indications (United States): The Diamondback 360 Coronary Orbital Atherectomy Systems (OAS) are percutaneous orbital atherectomy systems indicated to facilitate stent delivery in patients with coronary artery disease (CAD) who are acceptable candidates for PTCA or stenting due to de novo, severely calcified coronary artery lesions.
Contraindications: The OAS are contraindicated when the ViperWire® guide wire cannot pass across the coronary lesion or the target lesion is within a bypass graft or stent. The OAS are contraindicated when the patient is not an appropriate candidate for bypass surgery, angioplasty, or atherectomy therapy, or has angiographic evidence of thrombus, or has only one open vessel, or has angiographic evidence of significant dissection at the treatment site and for women who are pregnant or children.
Warnings/Precautions: Performing treatment in excessively tortuous vessels or bifurcations may result in vessel damage; The OAS was only evaluated in severely calcified lesions; A temporary pacing lead may be necessary when treating lesions in the right coronary and circumflex arteries; On-site surgical back-up should be included as a clinical consideration; Use in patients with an ejection fraction (EF) of less than 25% has not been evaluated. See the instructions for use before performing Diamondback 360® Coronary OAS procedures for detailed information regarding the procedure, indications, contraindications, warnings, precautions, and potential adverse events.
