Below is an educational, technical answer to a question many patients and clinicians ask. 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. 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
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. 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.
Who is eligible for mechanical thrombectomy?
Eligibility generally centers on a confirmed large-vessel occlusion, the time from symptom onset, and imaging indicating salvageable brain tissue. Additional clinical factors and stroke severity are weighed in the decision. Because the assessment is time-critical and imaging-dependent, it is made rapidly by the treating stroke team. This content is educational and does not establish eligibility for any individual patient.
What This Means in Practice
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. All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU.
Key Considerations
- 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.
- Liquid embolic use requires attention to concentration, radiopacity, and injection control for the target lesion.
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 regulatory status of these neurovascular devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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.
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. Liquid embolic use requires attention to concentration, radiopacity, and injection control for the target lesion. INVAMED's InWIRE Neurovascular Guidewire and neurovascular microcatheters and distal access catheters support this access role. 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. Manufacturer statements, including the described up-to-24-hour window for the KinG device, reflect product content and do not establish individual eligibility. The choice of aspiration, a stent retriever, or a combined approach is made by the operator based on clot and vessel characteristics. 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.
