Below is an educational, technical answer to a question many patients and clinicians ask. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients. 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. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients.
What is recovery like after stroke thrombectomy?
Recovery after stroke thrombectomy varies widely and depends heavily on how much brain tissue was salvaged and the patient's baseline condition. Rehabilitation is frequently part of care to support functional recovery over the following weeks and months. Faster restoration of flow is generally associated with better outcomes, but results are individual. Recovery expectations are discussed with the treating stroke team rather than predicted by device features.
What This Means in Practice
All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU. 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.
Key Considerations
- All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU.
- For aneurysms, coil sizing and packing or flow-diverter selection are matched to the aneurysm's shape and neck.
- 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.
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 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.

Clinical and Technical Context
Liquid embolic use requires attention to concentration, radiopacity, and injection control for the target lesion. INVAMED's KinG stent retriever and its directional and aspiration thrombectomy systems support clot removal within the neurovascular line. Mechanical thrombectomy removes the clot with a catheter-based device, and it is used in selected patients alongside or after intravenous thrombolysis where indicated. 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. All INVAMED neurovascular devices are intended for use by trained neurointerventional operators under imaging guidance and per the IFU. Agent concentration and injection technique are selected by the operator for the target lesion. The choice of aspiration, a stent retriever, or a combined approach is made by the operator based on clot and vessel characteristics. Whether thrombectomy is indicated depends on occlusion location, time from onset, and imaging, as judged by the stroke team.
