According to FutureWise analysis the atherectomy devices market in 2025 is US$0.92 billion, and is expected to reach US$ 1.68 billion by 2033 at a CAGR of 7.8%. The market's expansion can be linked to a growing prevalence of peripheral artery disease (PAD) and a heightened preference for minimally invasive procedures. Additionally, advancements in technology—such as directional, rotational, and laser atherectomy systems—are improving both procedural efficiency and patient outcomes, contributing to the expansion of the market.
Atherectomy devices are specialized medical instruments used in minimally invasive procedures to treat atherosclerosis. Atherosclerosis is a condition characterized by the buildup of plaque in the arteries, which can restrict blood flow and lead to serious cardiovascular complications. These devices are designed to remove or modify plaque from the walls of arteries, thereby restoring blood flow and improving vascular health. Atherectomy is often employed when traditional treatments, such as balloon angioplasty or stenting, are insufficient, especially in cases involving heavily calcified or complex lesions.
The primary function of atherectomy devices is to physically remove or ablate plaque, which consists of cholesterol, calcium, and fibrous tissue, from the inner lining of arteries. Unlike angioplasty, which compresses plaque against the arterial wall, atherectomy actively excises or vaporizes it. This approach reduces the risk of vessel trauma and improves long-term outcomes. Atherectomy devices are commonly used in both coronary and peripheral arteries to address conditions like coronary artery disease and peripheral artery disease.
There are several types of atherectomy devices, each utilizing distinct mechanisms: Directional atherectomy devices cut plaque using a rotating blade; rotational atherectomy employs a high-speed, diamond-coated burr to grind away calcified plaque; laser atherectomy uses light energy to vaporize obstructions; and orbital atherectomy combines rotational and orbital motion for precise plaque modification. The choice of device depends on the composition and location of the plaque, as well as patient-specific factors.
Atherectomy procedures are typically performed under imaging guidance, such as fluoroscopy, to ensure precision and safety. The benefits of these procedures include improved vessel patency, reduced rates of restenosis, and enhanced outcomes in complex cases. However, risks such as vessel perforation or embolization require skilled operators and careful patient selection. As cardiovascular technology advances, atherectomy devices continue to evolve, offering safer and more effective solutions for managing atherosclerosis.
Image Guidance, Diagnostics & Smart Features: The growing use of imaging tools like IVUS and OCT is enhancing directional atherectomy. Some OEMs are adding features for predictive maintenance and data capture, such as logging cutter torque and flow, to improve safety and performance.
