7Neurovascular Mechanical Thrombectomy



Penumbra System®
The Penumbra System® is a fully-integrated system designed specifically for mechanical thrombectomy by aspiration. It is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusion. The Penumbra System includes Reperfusion Catheters, Hi-Flow Aspiration Tubing, and Pump MAX™ aspiration pump and its accessories.

Penumbra SMART COIL®
The Penumbra SMART COIL® System is a platinum embolization device comprised of complex Standard and Soft coils that change softness profile within the span of a single coil. These families of SMART COIL integrate aneurysm framing, filling, and finishing in that the coil becomes progressively softer as it is deployed. These coils can be used to pack even the most delicate aneurysms. All SMART COILS feature UltraHD Fiber designed to provide stretch resistance and flexibility at the coil/pusher interface.

Multiple softness levels: Standard, Soft, Extra Soft
Consistent, instant mechanical detachment
Compatible with .0165" and .017" inner diameter microcatheters
