KinG Intracranial Revascularization Device
A stent retriever or flow restoration device for acute ischemic stroke, capturing and removing large clots from the intracranial arteries, swiftly restoring perfusion.
The King Vascular Revascularization Device is a stent-based retrieval system designed to restore cerebral blood flow in patients presenting with acute ischemic stroke due to large intracranial vascular occlusion. Incorporating overlapping stent technology, King Vascular effectively captures and removes thrombus while reinvigorating cerebral perfusion—making it a rapid and innovative approach for neurovascular revascularization.
Overlapping Stent Construction
- Enhanced Clot Capture: The device’s multi-layer stent struts increase contact with thrombus, improving retrieval efficacy in large or tough clots.
- Optimized Vessel Conformability: Overlapping cells allow the stent to adapt closely to the tortuous geometry of intracranial arteries, ensuring stable engagement throughout the retrieval process.
Neurovasculature Compatibility
- Broad Anatomical Coverage: Suitable for the internal carotid artery (ICA), M1/M2 segments of the middle cerebral artery, basilar, and vertebral arteries.
- Dedicated Neurovascular Materials: Constructed to retain flexibility in smaller-caliber and curved intracranial vessels, reducing the risk of vessel trauma during navigation and retrieval.
Rapid & Innovative Clot Retrieval
- Seamless Deployment: Designed for rapid insertion and retrieval under fluoroscopic guidance, decreasing overall device manipulation.
- High Visibility Markers: Radiopaque markers along the stent struts ensure precise positioning and real-time feedback under angiography.
Flow Restoration
- Improved Patency: The stent lattice temporarily expands the occluded segment, promoting partial or complete flow restoration even before full clot retrieval.
- Multiphase Extraction: Operators can perform multiple passes if needed, targeting residual thrombus while maintaining cerebral perfusion.
