Abstract
The embolic protection device (10) has an expandable tubular structure supporting a filter mesh material (12). The embolic protection device is compressed to a small diameter for insertion into a patient's aorta, then expanded within the aorta with the filter mesh material positioned to allow blood to enter sidebranch vessels connected to the aorta and to prevent embolic material from entering the sidebranch vessels. The filter mesh material may be configured with waves or undulations (26) for increased surface area and/or with two layers of mesh material to provide additional protection against embolization and to prevent inadvertent occlusion of the sidebranch vessels.
