Spider™ Intracranial Coil System (Detachable Pushable)

A detachable coil system for intracranial or peripheral aneurysm coiling, featuring instant mechanical detachment and optimized volumetric packing.

Spider™ Intracranial Coil System (Detachable Pushable), introduced by Invamed—a global medical device manufacturer—is engineered for aneurysm occlusion and neurovascular lesion management within the cerebral circulation. By integrating a pushable yet detachable coil design, Spider™ offers precise in-place coil release and repositioning, crucial for intracranial aneurysms requiring exact coil deployment to avoid unintended protrusion or migration.

Detachable Pushable Deliver

Combines the simplicity of pushable coil insertion with controlled detachment, enabling user-friendly repositioning and reducing the risk of coil misplacement.

High radiopacity ensures real-time fluoroscopic visibility, aiding neurosurgeons or interventional neuroradiologists in achieving optimal coil packing density.

The coil’s flexibility suits cerebral aneurysm sacs and curved neurovascular anatomies, preventing excessive stress on delicate vessel walls.

Ideal for intracranial saccular or fusiform aneurysms, arteriovenous malformations (AVMs), or other complex neurovascular anomalies necessitating endovascular embolization.

Intracranial aneurysm occlusion, small AVM feeding vessel occlusion, salvage of vascular malformations within the cerebral circulation.

Vessels too small or tortuous for microcatheter navigation, active infection at the access site, or cases where coil retrieval is not an option.
