Neurovascular Stents Market Analysis | United States | 2020-2026 | MedCore
There are two main types of neurovascular stents currently on the market, the traditional stent and the flow diverter stent. They are both used as treatments for cerebral aneurysms. Traditional neurovascular stents are small, flexible, tube-like devices used for stabilizing detachable coils within an aneurysm. They serve to block off the aneurysm and to prevent coils from slipping back into the main blood vessel. These stents are also used to treat intracranial stenosis by opening blocked arteries. These stents are delivered in reduced tube structures for easier navigation and delivery through the narrow intracranial vessels. As brain arteries are more fragile than carotid arteries, a self-expanding stent that gently opens to the desired vessel diameter is generally used. Self-expandable stents carry a lower risk of dissection or vessel rupture when compared to the balloon-expandable stents.

Neurovascular guidewires are used in conjunction with microcatheters, which are used to place coils or stents at intracranial locations to treat conditions such as aneurysms and cerebral arteriovenous malformations. Guidewires are inserted into patients through a small incision near the groin and maneuvered through the vascular system to the targeted area. The microcatheter can then be threaded over the guidewire to the treatment area. There is a wide selection of guidewires available and subtle differences between each product allow them to be used for different applications. Important properties of guidewires include flexibility, stiffness, hydrophilic coating, low friction navigation and high torqueability. A torque device can be used to aid navigation and rotation of the guidewire.

Neuroendoscopy is a rapidly expanding field of neurosurgery. Neuroendoscopy involves the use of a small fiber-optic camera attached to an endoscope that is a few millimeters in diameter. Neuroendoscopes combine high quality fiberoptic images with flexible and steerable designs that allow neurosurgeons to visualize their target deep within the brain without disrupting other vital structures. In order to transmit extremely accurate images to the neurosurgeon, there have been innovative advances in lens design and optical physics over the last decade. Smaller fiberoptic scopes with improved image quality, as well as three-dimensional imaging, have contributed to advancements within this market. An endoscope can also be utilized with or without stereotactic techniques.

Neurovascular catheters, also known as microcatheters, are a type of catheter small enough to be used in neurovascular procedures. The devices are very narrow in order to traverse the fine vessels within the brain. Microcatheters are designed with several properties in mind: hydrophilic coating, softness, trackability and stability. Neurovascular catheters are to deliver detachable coils, stents, liquid embolics and pharmaceutical products directly to the brain. They are often used for treating aneurysms, arteriovenous malformations (AVMs), trauma and strokes. Microcatheters are offered with different varieties of tips, which allow physicians to choose the appropriate tip for a specific location in the brain. The devices also vary in diameter, which is measured in French (F) size, where one F is equal to 0.33 mm. Although tip and diameter can vary widely, microcatheters are grouped by guiding systems. There are three types of microcatheters: over-the-wire, flow directed including the new detachable tip versions and guide catheters.

Ischemic Stroke is caused by an obstruction within a blood vessel that is supplying blood to the brain. This is often caused by blood clots but can also be caused by other substances like plaque. The gold standard treatment for strokes for many years has been the administration of clot dissolving or clot busting medication called tissue plasminogen activator (tPA). This type of drug must be administered as soon as possible, with a four hour window from symptom onset, to increase chances of recovery. A significant number of patients do not get to healthcare facilities quickly enough to meet that window and even some of those who do, later experience hemorrhagic complications from the medication. It is very effective for smaller clots but often fails to break up larger clots. Some patients cannot receive tPA, in which cases physicians rely on antiplatelet or anticoagulant medicine to ensure blood clots do not get larger.

An intrathecal pump is an implantable medical device that delivers medication to the intrathecal space surrounding the spinal cord. The drug pump reduces the reliance of patients on oral or intravenous medications and can minimize the associated side effects while controlling their symptoms. Lower doses of medications are generally required since the drug delivery is more targeted. Before a pump is implanted into the patient, the therapeutic effect of the intrathecal opioid therapy is tested with an external pump; the pump is not implanted if there are no clear and satisfactory effects in the trial application.

Detachable coil embolization is a minimally invasive method of treating brain aneurysms and cerebral blood vessel malformations. The detachable coil embolization treatment of cerebral aneurysms is less invasive and requires less recovery time than open surgery. An aneurysm is a weakened area in the wall of an artery in the brain. This area bulges in the artery and if it ruptures it can lead to a bleed in the brain and cause stroke, brain damage and even death. Interventional neuroradiologists will typically perform the detachable coil embolization process to alleviate dangers associated with aneurysms.

Devices in the cerebrospinal fluid (CSF) management market are mainly used for the treatment of hydrocephalus. Hydrocephalus, or water on the brain, refers to an abnormal buildup of CSF in the brains ventricles. Under normal biological conditions, equilibrium between the production, circulation and absorption of CSF is maintained in the ventricular cavities of the brain as CSF is continually drained away into the circulatory system. Hydrocephalus can result when absorption of fluid into the bloodstream is blocked which leads to an accumulation of CSF. This condition can result in increased intracranial pressure inside of the skull and can lead to tunnel vision, mental disability, progressive enlargement of the head and even death. Symptoms due to the increased intracranial pressure include headaches, nausea, vomiting, papilledema, coma or sleepiness. Further elevation of intracranial pressure can result in uncal and/or cerebellar herniation.

Balloon occlusion devices have inflatable balloon devices at their distal end which can be expanded to occlude an artery. Balloon occlusion devices serve a number of purposes in neurovascular procedures. They can be used to assist detachable coil procedures, similarly to stents, however these devices are temporary. In these cases they are being used to aid in the treatment of aneurysms, AVMs or fistulas. When using detachable coils there is a risk of the coils blocking flow of the parent artery if they occlude the lumen of the artery as well. In order to minimize this risk, the balloon is inflated inside the parent artery prior to the insertion of coils so that they can be packed tighter inside the aneurysm without the danger of them protruding into the lumen. A study looking at this technique in anterior aneurysms found that there was a lower complication rate with balloon assisted coiling in comparison to coiling alone however other studies have found the opposite therefore further studies are required. In some cases, balloon catheters can also be used for the placement of stents. There are a number of factors that could impact the choice to use this device for aneurysm treatment such as the clinical situation, physicians preference, and the morphology of the aneurysm. It is worth noting that the ASP of these devices is considerably less than stents which could impact device preference as well.

An aneurysm clip is a permanent fixture in the brain that resembles a tiny coil-spring clothespin made of titanium or a cobalt chromium nickel alloy. Biocompatible aneurysm clips used in the neurosurgical field are available in a variety of shapes and sizes, with known closing pressures. Aneurysm clips are placed at the neck of an aneurysm and serve to isolate the thin-walled aneurysm from arterial flow without obstructing the parent artery or other perforating arteries. Aneurysms are a localized, blood-filled balloon-bulge in the wall of a blood vessel. As an aneurysm grows, it becomes thinner and more prone to leaking or rupture. If this occurs, blood is released into the spaces around the brain, leading to a subarachnoid hemorrhage (SAH).
more...Liquid Embolics Market Analysis | United States | 2020-2026 | MedCore
Liquid embolics currently on the market include N-butyl cyanoacrylate (NBCA) (TRUFILL®) and an ethylene-vinyl alcohol copolymer (Onyx®). These agents are injected through microcatheters and act like glue in abnormal blood vessels. When they contact blood they solidify and obstruct the vessel lumen therefore blocking the flow of blood through malformed blood vessels and reducing the risk of rupture. The surgeon performing the procedure must flush the catheter before and after injecting the NBCA to prevent the liquid agent from sticking to the catheter. Thus this procedure requires a highly skilled physician. This is often done prior to the removal of these vessels in order to simplify the surgical procedure.
