TEMPORARY EMBOLIC PROTECTION DEVICE AND MEDICAL PROCEDURE FOR DELIVERY THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an embolic protection device preventing undesired embolic material from entering branch vessels of a main vessel, such as the aortic arch.SOLUTION: There is provided a collapsible embolic protection device devised for temporary transvascular delivery to an aortic arch 100 of a patient, including a protection unit that comprises a selectively permeable unit 132 adapted to prevent embolic material 150 from passage with a blood flow from entering into a plurality of aortic side branch vessels 116, 118, and 120 at the aortic arch. The protection unit is permanently attached to a transvascular delivery unit 130 at a connection point provided at the selectively permeable unit, and a first support member for the protection unit that is at least partly arranged at a periphery of the selectively permeable unit. The first support member is configured to be bent off-center toward the connection point and/or the transvascular delivery unit.SELECTED DRAWING: Figure 3
