Emboli guarding device

摘要

A device including a stent structure or frame to which a sheet is attached for use in minimizing or preventing emboli, particles. and/or air bubbles from migrating into certain areas of the anatomy. The device can be placed in the blood stream in an area of the heart, such as the aortic arch, to direct particles toward the descending aorta rather than toward the brain. The sheet of the device can be a thin film material, which may include multiple fenestrations that are smaller in size than the particles that are to be filtered.
