Cardiovascular Systems Announces First Peripheral Arterial Disease Case Treated with New, Low-Profile, 60cm Diamondback Peripheral System

ST. PAUL, Minn.--(Healthcare Sales & Marketing Network)--Cardiovascular Systems, Inc. (CSII) (CSI), today announced the first use of its Diamondback 360® 60cm Peripheral Orbital Atherectomy Systems (OAS) for the treatment of peripheral arterial disease (PAD). Jihad A. Mustapha, M.D., FACC, FSCAI, Director of Heart and Vascular at Metro Health Hospital in Wyoming, Mich., performed the procedure through Tibiopedal access using the new, low-profile device.

“CSI’s new 60cm, 4 French devices provide physicians with broader treatment options for challenging lesions in the lower leg,” said David L. Martin, CSI president and chief executive officer. “If left untreated, these cases may result in lower limb amputation. Our new 60cm Diamondback devices use smaller sheaths, which have been shown to reduce procedure times and decrease complications from bleeding, enabling quicker patient recovery.”

CSI’s Diamondback 360 Peripheral OAS allows physicians to gain access through the foot or ankle to treat PAD in the small vessels located below the knee due to its very small profile and short length. The recently approved Diamondback 360 60cm Peripheral OAS devices are available in two crown designs, the 1.25mm Micro Crown, and the 1.25mm Solid Crown. Each crown offers a shorter shaft length and a smaller more flexible shaft than their predecessors for improved ease of use.

Said Dr. Mustapha, “Many of the patients we treat have advanced PAD and suffer from Critical Limb Ischemia, or CLI. These patients often have complex, calcified lesions in their lower leg which are challenging to access and treat using the traditional femoral artery access site. CSI’s new orbital atherectomy system now allows us more options to treat those lesions by providing a low-profile system that is fully compatible with alternative access sites in the foot or ankle. Having a variety of treatment options allows us to treat a broader range of patients who may otherwise be facing amputation.”

The Diamondback 360 Peripheral OAS uses a patented combination of differential sanding and centrifugal force to reduce arterial plaque, including calcium, which can cause complications when treating PAD. Calcium is present in about 65 percent of the 2.5 million people diagnosed annually with PAD and leads to poor outcomes and higher treatment costs when traditional balloon and stent therapies are used—including dissection, vessel wall trauma and stent fracture.

About Peripheral Arterial Disease

More than 12 million Americans, most over age 65, suffer from PAD, which is caused by the accumulation of plaque in peripheral arteries (commonly the pelvis or leg) reducing blood flow. Symptoms include leg pain when walking or at rest. Left untreated, PAD can lead to severe pain, immobility, non-healing wounds and eventually limb amputation. With risk factors such as diabetes and obesity on the rise, the prevalence of PAD is growing at double-digit rates.

Millions of patients with PAD may benefit from treatment with orbital atherectomy utilizing the Stealth 360 and Diamondback 360, minimally invasive catheter systems developed and manufactured by CSI. These systems use a diamond-coated crown, attached to an orbiting shaft, which sands away plaque while preserving healthy vessel tissue—a critical factor in preventing reoccurrences. Balloon angioplasty and stents have significant shortcomings in treating hard, calcified lesions. Stents are prone to fractures and high recurrence rates, and treatment of hard, calcified lesions often leads to vessel damage and suboptimal results.

Product Disclosure

The Diamondback 360® Peripheral Orbital Atherectomy Systems are percutaneous orbital atherectomy systems indicated for use as therapy in patients with occlusive atherosclerotic disease in peripheral arteries and stenotic material from artificial arteriovenous dialysis fistulae. The peripheral systems are contraindicated for 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.
