key when designing and producing neurovascular devices. For over 30 years, Quasar has specialized in sub-micron manufacturing, supported by a highly-skilled operations team and processes engineered to deliver finished products with detailed-oriented targets. From prototyping to mass production, Quasar offers full turnkey solutions to ensure the reliability and optimal performance of your device.
Ischemic strokes: Caused by clots in one or more of the brain’s vasculature.
Cerebral aneurysms: An enlarged or bulging artery or capillary within the brain.
Arteriovenous malformation: Defective group of arteries and veins resulting in a disruption in the blood flow and oxygen supply to the brain.
Fistulas: An abnormal connection of blood vessels within or around the brain, resulting in diminished or lack of nutrient supply to local brain cells.
Other NV Diseases
Interventional neurology (IN) deals with the diagnosis and treatment of neurovascular (NV) disorders, i.e., concerning the brain and central nervous system (CNS). Devices typically used in IN include endovascular catheters that are function-specific, angiography, and fluoroscopy.
The brain is the most perfused organ in the human body, requiring 25% of the body’s oxygen intake. Because the brain lacks the means for storing oxygen and glucose, any imbalance in the brain is a medical emergency. Thus, any impediment or disorder that causes a blockage or an imbalance in blood flow must be removed immediately.
Interventional neurology devices include :
Coil Embolization Devices: These are used to treat aneurysms (a bulging artery or capillary) within the brain. A steerable microcatheter with a maximum thickness of 1.5Fr is used to deliver a filling glue, mesh stent, or platinum wire that coils and is released at the site. Any one of these processes helps prevent the rupture of the aneurysm.
Cerebral balloon angioplasty: The catheter tip is an expandable balloon for removing blockages or creating an occlusion that prevents rupture of the blood vessel. The balloon is controlled by the neurologist and can expand under high or mid-level pressure, in which case balloons are made from polyester or complex polyurethanes. The balloon may even be required to expand up to 8 times its normal size, i.e., highly flexible in nature and hence made from silicone or another increasingly popular choice: Nitinol (shape memory alloy, SMA).
Stenting systems: Neurovascular stents require a much finer design and construction, and need to be far more flexible and elastic than cardiovascular stents. Shape memory polymer (SMP) stents are better suited to neurovascular procedures.
Neurothrombectomy devices: These use mechanical, ultrasound, and other means of minimally invasive catheter-based techniques to remove clots formed in the neurovascular system. They are primarily used on patients who have had an ischemic stroke.
Micro-catheter tubes are made from engineered advanced polymers and carry interlocking, movable parts. Quasar offers specialized automated precision extrusion, tubing, and micro-assembly production lines for both high and low volumes. Our highly skilled operators employ special fabrication and assembly tools under a microscope for precise assembly. Regular employee training ensures reliable production every single time.
With Quasar, you can rest assured that the sourcing of materials, micro-assembly, and complete IP protection for your novel NV device is handled with the utmost care. Quasar delivers best-in-class medical devices that even exceed regulatory requirements, so your brand takes the stand as the market leader.
