Cerebral embolic protection assembly and method of use
First Claim
1. An aortic catheter comprising:
- an elongated shaft;
a cerebral embolic protection assembly mounted to said elongate shaft and positioned on said elongated shaft such that, when the aortic catheter is in an operative position, said cerebral protection assembly is positioned within a lumen of an aortic arch of a patient, said cerebral embolic protection assembly having a deployed position wherein said cerebral embolic protection assembly is configured to partition the lumen of the aortic arch longitudinally into a first fluid flow channel in fluid communication with the aortic arch vessels and a second fluid flow channel in fluid communication with the patient'"'"'s corporeal circulation and wherein said cerebral embolic protection assembly is configured to allow blood flow to enter the cerebral circulation while excluding emboli from the cerebral circulation.

Abstract
The present invention is related to cerebral embolic protection assemblies (CEPA) to be used during a medical procedure to help redirect or catch emboli before it is pumped into the cerebral circulation. A variety of CEPA'"'"'s are disclosed including a perfusion filter catheters and fluid flow dividers for capturing and redirecting potential emboli within the aorta during heart surgery and cardiopulmonary bypass. The catheter devices may further include one or more additional or auxiliary flow control members. Furthermore, oxygenated blood is perfused through a perfusion lumen in the catheter. The present invention describes devices that are capable of capturing and/or redirected emboli away from the cerebral circulation. The devices are configured for percutaneous, intercostal, lateral or central insertion with attendant administration of cardiopulmonary bypass and cardioplegic arrest with protection from undesirable embolic events.

-
an elongated shaft;
a cerebral embolic protection assembly mounted to said elongate shaft and positioned on said elongated shaft such that, when the aortic catheter is in an operative position, said cerebral protection assembly is positioned within a lumen of an aortic arch of a patient, said cerebral embolic protection assembly having a deployed position wherein said cerebral embolic protection assembly is configured to partition the lumen of the aortic arch longitudinally into a first fluid flow channel in fluid communication with the aortic arch vessels and a second fluid flow channel in fluid communication with the patient'"'"'s corporeal circulation and wherein said cerebral embolic protection assembly is configured to allow blood flow to enter the cerebral circulation while excluding emboli from the cerebral circulation. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 38, 39, 40, 41, 42, 43, 44, 45, 46)

24. A cerebral embolic protection assembly comprising:
a body having an upper surface and a lower surface, said body being configured to be inserted in an operative position within a lumen of an aortic arch of a patient with said upper surface facing toward the aortic arch vessels and said lower surface facing away from the aortic arch vessels, said body having a deployed position wherein said body is configured to partition the lumen of the aortic arch longitudinally into a first fluid flow channel in fluid communication with the aortic arch vessels and a second fluid flow channel in fluid communication with the patient'"'"'s corporeal circulation and wherein said body is configured to allow blood flow to enter the cerebral circulation while excluding emboli from the cerebral circulation.

37. A method of cerebral embolic protection comprising:
-
inserting a cerebral embolic protection assembly into an operative position within a lumen of an aortic arch of a patient with an upper surface of the cerebral embolic protection assembly facing toward the aortic arch vessels and a lower surface of the cerebral embolic protection assembly facing away from the aortic arch vessels; and
deploying the cerebral embolic protection assembly to partition the lumen of the aortic arch longitudinally into a first fluid flow channel in fluid communication with the aortic arch vessels and a second fluid flow channel in fluid communication with the patient'"'"'s corporeal circulation, wherein the cerebral embolic protection assembly allows blood flow to enter the cerebral circulation while excluding emboli from the cerebral circulation.
