Below is an educational, technical answer to a question many patients and clinicians ask. 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
Patient eligibility, the treatment window, and device selection are all determined by the treating neurointerventional team using imaging and current criteria. Intracranial aneurysms are focal outpouchings of a brain artery wall, and endovascular options aim to seal the aneurysm from circulation to reduce rupture risk. Because brain tissue is highly time-sensitive, rapid restoration of flow is central to endovascular stroke care in eligible patients.
What is the success rate of mechanical thrombectomy?
Success in thrombectomy is often described in terms of reperfusion grading and the proportion of patients achieving good downstream flow. Reported reperfusion rates in the literature are high for modern devices, but they reflect studied populations rather than an individual guarantee. Outcomes also depend on how quickly flow is restored and on the patient's baseline status. Individual prognosis is a matter for the treating clinician rather than a fixed figure.
What This Means in Practice
For aneurysms, coil sizing and packing or flow-diverter selection are matched to the aneurysm's shape and neck. 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.

Frequently Asked Questions
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 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.

Clinical and Technical Context
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. Coil sizing and packing strategy are determined by the neurointerventionalist for the specific aneurysm. 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. Speed to reperfusion is a central factor in stroke thrombectomy, which shapes device readiness and workflow in eligible patients. Whether a flow diverter is appropriate, versus coiling, is a specialized decision made by the treating clinician. Patient eligibility, the treatment window, and device selection are all determined by the treating neurointerventional team using imaging and current criteria.
