This article explains, in educational terms, detachable coils aneurysm — how the technology works and where it fits. Mechanical thrombectomy removes the clot with a catheter-based device, and it is used in selected patients alongside or after intravenous thrombolysis where indicated. 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
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. 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.
Detachable Coil Embolization
Detachable coils are soft platinum-based coils packed into an aneurysm sac to promote clotting and seal the aneurysm from circulation. Controlled detachment lets the operator position and, if needed, reposition a coil before releasing it. INVAMED's Spider Intracranial Coil System uses a platinum-tungsten 92/8 percent alloy in detachable and pushable configurations with instant mechanical detachment; according to INVAMED, Spider coils provide aneurysm packing across 2 to 30 mm coil diameters. Coil sizing and packing strategy are determined by the neurointerventionalist for the specific aneurysm.
Design and Technical Notes
INVAMED's neurovascular portfolio spans clot retrieval, aspiration, aneurysm packing, embolization, and the access tools that reach the intracranial circulation. Manufacturer statements, including the described up-to-24-hour window for the KinG device, reflect product content and do not establish individual eligibility. Speed to reperfusion is a central factor in stroke thrombectomy, which shapes device readiness and workflow in eligible patients.
Key Considerations
- Speed to reperfusion is a central factor in stroke thrombectomy, which shapes device readiness and workflow in eligible patients.
- Manufacturer statements, including the described up-to-24-hour window for the KinG device, reflect product content and do not establish individual eligibility.
- For aneurysms, coil sizing and packing or flow-diverter selection are matched to the aneurysm's shape and neck.
Frequently Asked Questions
What treatment window does INVAMED cite for the KinG device?
According to INVAMED product content, the KinG device is described as capturing and extracting cerebral artery clots within a treatment window of up to 24 hours; eligibility is a clinical determination.
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.
About INVAMED
INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED states it maintains a growing portfolio of international patents across its device range.
Clinical and Technical Context
INVAMED's KinG Intracranial Revascularization Device is a self-expanding nitinol stent retriever with platinum markers at the proximal and distal ends of the basket for fluoroscopic visualization, intended for vessels including the internal carotid, middle and anterior cerebral, and basilar and vertebral arteries. Clot characteristics and vessel tortuosity influence whether a stent retriever, aspiration, or combined technique is chosen. 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. INVAMED's neurovascular portfolio includes flow diverter stents for this parent-vessel reconstruction approach to selected aneurysms.
