Penumbra Inc.'s ischemic stroke device platform, the Penumbra System, is designed to revascularize or open up a blood vessel that is blocked by a blood clot. The pathology of brain tissue starved of oxygen by a blocked blood vessel is a gradual progression from reversible ischemia to irreversible infarction (cell death). The penumbra, a rim of ischemic but still viable tissue that surrounds a central core of infarction, has consistently been shown in animal models to be salvageable if blood flow can be restored within a certain time window.
