Abstract:
An embolic protection device for use in a patient's blood vessel, such as the aorta, has an approximately cylindrical outer structure made of a filter mesh material and an approximately conical inner structure also made of a filter mesh material. On the downstream end of the embolic protection device, the wider end of the conical inner structure is joined to the cylindrical outer structure. The upstream end of the embolic protection device is open for blood to flow between the conical inner structure and the cylindrical outer structure. The space between the conical inner structure and the cylindrical outer structure defines a collection chamber for captured emboli. The narrow upstream end of the conical inner structure has a catheter port with a resilient seal that is sized for passage of a catheter shaft. The filter mesh material may be self-supporting or it may be supported on a resilient-framework or an inflatable framework.

Claim (Index 10):
A method for advancing a catheter over an aortic arch, said method comprising:\n providing an embolic protection device comprising a cylindrical outer sleeve including a filter mesh material and an inner structure including a filter mesh material and having a resilient seal comprising a plurality of flaps, wherein a wide base of the inner structure is attached to a downstream end of the cylindrical outer sleeve and the resilient seal of the inner structure is located at an upstream end of the cylindrical outer sleeve; positioning the embolic protection device in the aorta and covering the aortic vessels with the upstream end of the cylindrical outer sleeve facing the heart; and advancing the catheter from the downstream end of the embolic protection device through the resilient seal toward the heart; wherein emboli generated upstream of the emboli protection device flow into and are trapped within a collection chamber defined at the downstream end of the embolic protection device between an inner surface of cylindrical outer structure and an outer surface of the inner structure.
