Abstract
A catheter configured to provide a delivery system for standard interventional devices and for rapid localized deep cooling to organs at risk of ischemia-reperfusion injury during procedures such as intracranial thrombectomy or emergency thrombectomy. The catheter is comprised of an insulative shaft with a multi-component braided outer lumen and an internal floating inner lumen with a plurality of structures configured to minimize contact and resulting heat transfer between the two lumens.
