Intracranial Stenosis Stents Market: Improving Blood Flow to the Brain

Intracranial stenosis refers to the narrowing of blood vessels in the brain. Usually, the narrowing of the blood vessels happens due to a condition called atherosclerosis, which is the buildup of cholesterol, fat, and other substances on the artery walls. When a substantial amount of plaque builds up or a blood clot develops, the artery can get blocked and lead to the occurrence of strokes.

Intracranial stenosis stents are splints placed inside brain blood vessels to help heal or relieve an obstruction. In this blog post, we explain to you the insertion procedure and working of stents. Also, we shed light on how the intracranial stenosis stents market is expanding and what factors are propelling it forward. Read on!

How are Intracranial Stenosis Stents Inserted?

The first step of the procedure involves using a medical imaging technique called angiography to visualize the blood vessels. After this, the insertion of a catheter takes place (usually in the groin). The catheter is also threaded through the arteries and either in the neck or brain arteries, based on the location of the problem.

The stent delivery system carries the stent to the treatment location by following the same path as the catheter. Once placed, the stent expands to stick to the inside contours of the artery wall. Finally, the catheter is removed, and the stent stays in its position.

Market Stats

The intracranial stenosis stents market share is currently valued at USD 849.24 million and is anticipated to generate an estimated revenue of USD 1,620.02 million by 2032, according to the latest study by Polaris Market Research & Consulting, Inc. . Besides, the report notes that the market exhibits a robust 7.4% Compound Annual Growth Rate (CAGR) over the forecasted timeframe, 2023-2032.

How do Intracranial Stenosis Stents Work?

Intracranial stenosis stents act as permanent implants when used in the treatment of atherosclerosis in either intracranial or carotid arteries. Here, they open blocked arteries and improve the supply of blood to the brain. Angioplasty (a treatment option to widen blockages) and stent placement can be used together to prevent strokes among individuals who’ve had strokes or transient ischemic attacks (TIA).

What Do Stents Look Like?

A stent is a small mesh tube-like object. It’s made of metals like stainless steel, cobalt-chromium, or platinum-chromium. Also, nickel-titanium alloy called nitinol can be used to manufacture stents. As for the size, the diameter of stents typically ranges from 2.5 mm to 4.5 mm, with their lengths ranging between 10 to 20 mm.

The Self-Expanding Stents Segment Held the Largest Market Share

By product, the self-expanding stents accounted for the largest intracranial stenosis stents market share in 2022. This is largely because self-expanding stents hold the blood vessels open and ensure enhanced blood flow to the brain. Also, they’re generally considered a safe option for restoring blood flow in cases of acute ischemic strokes.

North America Dominates the Market

The Intracranial stenosis stents market growth in North America can primarily be attributed to the rising incidences of hypertension and stroke in the region. Also, the presence of well-established healthcare facilities impacts the market sales in the region favorably. According to the Center for Disease Control and Prevention (CDC), hypertension was the major cause of over 670,000 deaths in the United States in 2020.

Opening Blocked Arteries

Intracranial stenosis stents are mesh tubes used to hold open passages in the body. They help open blockages and improve blood supply to the brain. The rising incidence of stroke and the growing need for minimally invasive intricate surgeries are the major factors expected to drive the intracranial stenosis market demand over the forecast period.
