Abstract
Methods for treating total and partial occlusions employ a perfusion conduit which is penetrated through the occlusive material. Oxygenated blood or other medium is then perfused through the conduit to maintain oxygenation and relieve ischemia in tissue distal to the occlusion. Optionally, the occlusion may be treated while perfusion is maintained, typically by introducing a thrombolytic or other agent into the occlusive material using the perfusion conduit. Such methods are particularly suitable for treating acute stroke to prevent irreversible damage to the cerebral tissue.
