Atherectomy is a medical procedure performed by cardiology interventionists in treating peripheral artery disease (PAD). It can restore normal blood flow by removing plaque from the arteries. It can also treat other forms of PAD like critical limb ischemia (CLI) and claudicant. It is highly prevalent in patients above the age of 40 according to a report by the National Health and Nutrition Examination Survey. The high prevalence of PAD globally is expected to drive the worldwide atherectomy devices market.
The different types of devices used for this procedure are rotational, laser, directional, and orbital devices. Laser atherectomy has a 93% success rate in treating target lesion revascularization (TLR) in patients. Recently, Cardiovascular Systems Inc. received U.S. FDA (Food & Drug Administration) clearance for its Diamondback 360 Peripheral Orbital Atherectomy System. Its smaller size prevents medical complications.
Technological advances in atherectomy devices can remove even calcified plaque. Shockwave Medical has developed an angioplasty balloon which contains lithotripsy emitters. It is in the early stage of development but has seen success in trials in Europe. Medtronic’s two devices (“SilverHawk” and “TurboHawk”) have gained U.S. FDA approval in 2016. Both these devices can be used without the use of stents or percutaneous balloon angioplasty. It can reduce the chances of barotraumas and neointimal hyperplasia.
The worldwide atherectomy devices market is anticipated to reach USD 895 million by 2025. It was estimated at USD 488.04 million in 2016. It is expected to grow at a 7% CAGR over the forecast period (2014 - 2025). The market is driven by the increasing demand of minimally invasive surgery. Rising incidence of peripheral artery disease (PAD) is expected to spur market growth.
Directional atherectomy devices led the global market, on the basis of revenue, in 2016. This can be attributed to its capability to reduce the chances of barotrauma and neointimal hyperplasia. North America was the market leader in 2016 due to the FDA approval of medical devices and suitable reimbursement packages in the region. Key players in the global market are Spectranetics, Boston Scientific Corporation, Terumo IS (Interventional Systems), and Medtronic (Covidien).
