The medical arena continually moves toward a new technological revolution in a bid to serve better to a broader patient population, through an advanced set of technologies. Neurology, one of the most progressive medical branches, has recently encountered with a top-notch neurological area with unmatched expertise of digging inside the neural vessels.
Neurointervention is being considered a new hope for patients who have been suffering from severe neural disorders, such as strokes and aneurysm - over a long period of time. Minimally invasive compared to conventional surgeries, neurointervention involves delivery of medications through a catheter or cannula inserted through tiny incisions. The emergence of neurointervention branch has eventually fueled the innovation of medical devices specifically designed for performing neurointervention procedures. Neurovascular stents, embolic coils, liquid embolics, embolic protection devices, flow diverters, balloons, neurovascular thrombectomy devices, stent retrievers, and intrasaccular devices are among the key types of neurointervention devices.
The study revealed a few key procedures performed under neurointervention.
Coiling of Aneurysm
A little weakness in the arterial wall, and it might result in aneurysm, which is simply a blood vessel bulge filled with blood generally formed due to hypertension. Rupturing of an aneurysm is often fatal or sometimes causes a hemorrhagic stroke. Research by a team of neurological experts has proven that coiling an aneurysm can turn out to be a safer, more efficient, and more effective treatment in such a case. It ultimately prevents fatal rupture of an aneurysm.
Although endarterectomy has been a popular surgical procedure against carotid stenosis, it is not possible for every patient to access it. Carotid stenting has emerged as a critical, non-invasive alternative procedure with a filter device.
As the term suggests, arteriovenous malformation or AVM is an abnormal blood vessel tangle formed within the brain; it is usually present during the birth of a patient. In some cases, the abnormality increases in size and patients might suffer from severe headache, stroke symptoms, or seizures. In others, there might not be any symptoms. Symptomatic or asymptomatic, untreated AVM only increases the risk with a growing age. AVM embolization includes reduced blood flow to the site of the abnormality that potentially pulls down the risk of bleeding during the treatment.
What technology underpins the functioning of neurointerventional devices?
In case of both, brain-related or spinal disorders, neurology experts and practitioners insert catheters or cannulas to the respective sites through incisions, which enables them to view on a large screen the internal images of the brain or spine, all though the procedure. This underpins the concept behind spotting the exact inflicted area and identifying the precise problem.
According to a recent study by Future Market Insights, flow diverters and stent retrievers will continue to witness higher sales, compared to all other device types. In 2015, Future Market Insights evaluated the global market for neurointerventional devices beyond US$ 1.75 Bn. The study projects modest growth in sales of the devices over the next decade.
