About Penumbra’s Neuro Products

The Artemis Neuro Evacuation Device is intended for the controlled aspiration of tissue and/or fluid from the Ventricular System and/or Cerebrum. The Artemis Device works in conjunction with a neuroendoscope through a 19 F (6 mm) sheath. Artemis is a minimally invasive surgical tool that utilizes Pump MAX^™ for powerful and controlled hematoma evacuation.

Overview:

• Powerful and controlled aspiration with nearly pure vacuum (-29 inHg or 98.2 kPa)
• 14 mm burr hole with 19 F sheath for minimally invasive cranial access
• Compatible with nueroendoscope for working channels 1.6 — 2.9 mm
• Recessed bident at distal tip maintains cannula patency and aspiration

The Penumbra System is a fully integrated system designed specifically for mechanical thrombectomy by aspiration that first received 510(k) clearance by the U.S. Food & Drug Administration in December 2007.

The Penumbra System enables physicians to use aspiration, which acts like a minimally invasive “vacuum” inside the artery to remove stroke-causing blood clots from the brain safely and effectively. It is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusion. The latest generation of the Penumbra System features the Penumbra JET 7 with XTRA FLEX technology and Penumbra JET D Reperfusion Catheters, the 3D Revascularization Device^™, and Penumbra ENGINE and accessories. The Penumbra System includes the new Penumbra JET 7 Reperfusion Catheter with XTRA FLEX technology powered by the Penumbra ENGINE, offering the highest thrombus removal force for revascularization of acute ischemic stroke patients with large vessel occlusions.^a Thrombus removal is calculated based on catheter tip size and vacuum level of the aspiration source.
