This is a technical overview of an INVAMED device within the neurovascular interventions portfolio. 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. 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
Patient eligibility, the treatment window, and device selection are all determined by the treating neurointerventional team using imaging and current criteria. 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. Intracranial aneurysms are focal outpouchings of a brain artery wall, and endovascular options aim to seal the aneurysm from circulation to reduce rupture risk.

How It Works and Where It Fits
INVAMED's neurovascular portfolio spans clot retrieval, aspiration, aneurysm packing, embolization, and the access tools that reach the intracranial circulation. A flow diverter is a densely braided, low-porosity stent deployed across an aneurysm neck to redirect flow away from the sac while maintaining flow in the parent vessel. Reaching intracranial targets requires navigable microcatheters, distal access catheters, and neurovascular guidewires that track through tortuous cerebral vessels.
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.
- All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU.
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.
Who determines eligibility for thrombectomy?
The treating stroke team determines eligibility using imaging and current criteria; this article is educational and not medical advice.
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
INVAMED's neurovascular portfolio includes flow diverter stents for this parent-vessel reconstruction approach to selected aneurysms. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients. Clot characteristics and vessel tortuosity influence whether a stent retriever, aspiration, or combined technique is chosen. Manufacturer statements, including the described up-to-24-hour window for the KinG device, reflect product content and do not establish individual eligibility. Whether a flow diverter is appropriate, versus coiling, is a specialized decision made by the treating clinician. INVAMED's InWIRE Neurovascular Guidewire and neurovascular microcatheters and distal access catheters support this access role. All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU. Coil sizing and packing strategy are determined by the neurointerventionalist for the specific aneurysm. Mechanical thrombectomy removes the clot with a catheter-based device, and it is used in selected patients alongside or after intravenous thrombolysis where indicated. Liquid embolic use requires attention to concentration, radiopacity, and injection control for the target lesion. 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. According to INVAMED product content surfaced via its search index, the KinG device captures and extracts cerebral artery clots within a treatment window of up to 24 hours, though eligibility for any given patient is a clinical determination.
