This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating neurovascular interventions devices. Patient eligibility, the treatment window, and device selection are all determined by the treating neurointerventional team using imaging and current criteria. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Acute Ischemic Stroke and Intracranial Aneurysm Intervention
Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients. Intracranial aneurysms are focal outpouchings of a brain artery wall, and endovascular options aim to seal the aneurysm from circulation to reduce rupture risk. Patient eligibility, the treatment window, and device selection are all determined by the treating neurointerventional team using imaging and current criteria.
Regulatory Status and Manufacturing
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Portfolio and Sizing
Within this category, INVAMED lists devices such as KinG Intracranial Revascularization Device, Spider Intracranial Coil System, Libro Non-Adhesive Embolization Agent, Mantis Directional Thrombectomy System, AngioHAND Thrombus Removal System, InWIRE Neurovascular Guidewire. Size ranges, materials, and configurations are detailed in product documentation and the applicable IFU.
Key Considerations
- Liquid embolic use requires attention to concentration, radiopacity, and injection control for the target lesion.
- For aneurysms, coil sizing and packing or flow-diverter selection are matched to the aneurysm's shape and neck.
- Clot characteristics and vessel tortuosity influence whether a stent retriever, aspiration, or combined technique is chosen.
Frequently Asked Questions
What is the Libro embolization agent?
INVAMED's Libro is a non-adhesive liquid embolic agent combining EVOH copolymer, DMSO solvent, and tantalum for radiopacity, offered per INVAMED in multiple viscosity formulas for AVMs and tumors.
What is the INVAMED stent retriever called?
INVAMED's stent retriever is the KinG Intracranial Revascularization Device, a self-expanding nitinol device with platinum markers for fluoroscopic visualization.
What are Spider coils made of?
According to INVAMED, Spider Intracranial Coils are made of a platinum-tungsten 92/8 percent alloy and are offered across 2 to 30 mm coil diameters in detachable and pushable configurations.
Clinical and Technical Context
Patient eligibility, the treatment window, and device selection are all determined by the treating neurointerventional team using imaging and current criteria. The choice of aspiration, a stent retriever, or a combined approach is made by the operator based on clot and vessel characteristics. Clot characteristics and vessel tortuosity influence whether a stent retriever, aspiration, or combined technique is chosen. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients. INVAMED's KinG stent retriever and its directional and aspiration thrombectomy systems support clot removal within the neurovascular line. INVAMED's Libro Non-Adhesive Embolization Agent combines EVOH copolymer, DMSO solvent, and tantalum powder for radiopacity, and per INVAMED is offered in multiple viscosity formulas, including 6 and 8 percent concentrations, for cerebral AVMs and tumors. Acute ischemic stroke from a large vessel occlusion happens when a clot blocks a major brain artery, cutting off blood flow to a region of brain tissue. Aneurysm techniques include packing the sac with detachable coils and redirecting flow across the neck with a densely braided flow diverter so the sac thromboses over time.
