Here is what makes neurovascular testing different. Your stroke device must restore blood flow fast without tearing delicate brain vessels. Your embolic must solidify precisely without migrating downstream. We help you prove your device is both effective and safe enough for the brain where mistakes are not tolerated.
Neurovascular devices have no margin for error. Your thrombectomy system navigates tortuous anatomy to retrieve clots without tearing vessels. Liquid embolics must solidify in aneurysms without migrating downstream. Flow diversion stents deploy precisely in curved segments while maintaining flow. Each device type has distinct challenges.
We test navigation using anatomically accurate cerebrovascular models. Carotid tortuosity. Middle cerebral artery branching. Circle of Willis geometry. Our labs have high-resolution fluoroscopy and angiographic imaging. We capture flow restoration and vessel wall stress throughout interventions.
Your liquid embolic flows through microcatheters smaller than a millimeter. It has to solidify at exactly the right moment in exactly the right place. Too early, it clogs your catheter. Too late, it migrates to healthy vessels. We test deliverability through tortuous anatomy, precipitation timing in blood flow, and filling patterns in aneurysm models. This demonstrates your formulation achieves controlled, complete occlusion where you need it.
Your thrombectomy device needs to restore blood flow fast without tearing vessels or sending clot fragments downstream. We test clot engagement using different clot compositions and vessel geometries. We measure first-pass success rates and vessel wall preservation. We quantify time to recanalization. This shows whether your device achieves the rapid, complete reperfusion that saves brain tissue while protecting delicate cerebral vessels.
Your aspiration catheter creates suction forces on delicate brain vessel walls. We evaluate vascular endothelium after aspiration, assessing suction related damage, intimal integrity, and whether vessel walls remain structurally intact. Our pathologists score vessel trauma using standardized cerebrovascular grading aligned with FDA expectations. This demonstrates your catheter removes clots without causing the endothelial injury or vessel damage that increases hemorrhage risk after successful recanalization.
Your intracranial stent contacts cerebral vessel walls permanently. We evaluate vessel wall response at stent artery interfaces, measuring neointimal coverage, endothelialization progression, and inflammatory response at multiple timepoints. For flow diversion stents, we assess aneurysm occlusion progression and parent vessel healing. Our pathologists score tissue response using standardized grading scales aligned with FDA neurovascular expectations. This demonstrates your stent achieves therapeutic flow modification without causing chronic vessel wall injury or delayed complications.
Let's talk about your device. Thrombectomy. Embolic. Flow diversion. What it needs to prove. The cerebrovascular challenges it faces. We'll design a validation strategy that demonstrates effectiveness while protecting delicate vessels.
