    Abstract: An example medical device for treating a body lumen is disclosed. The medical device includes an expandable scaffold including first and second regions, each of the first and second regions include a plurality of interstices located therein. The medical device also includes a covering spanning each of the plurality of interstices of the first region. The second region is free of the covering. A biodegradable gripping material is disposed on an outer surface of the covering. Further, the expandable scaffold is configured to shift from a collapsed state to an expanded state and the second region is configured to contact an inner surface of the body lumen in the expanded state. Additionally, the gripping material is designed to initially prevent migration of the expandable scaffold upon implantation in the body lumen until the second region is secured to the inner surface of the body lumen.

    Abstract: An aortic arch embolic protection device may include an anchoring structure including a first anchoring ring at an upstream end and a second anchoring ring at a downstream end. A first filter element may extend from the first anchoring ring to the second anchoring ring and define a lumen through the aortic arch embolic protection device. A second filter element may be disposed within the lumen of the first filter element, wherein the second filter element includes an access port configured to facilitate passage of an interventional catheter through the access port. The anchoring structure may include a tubular scaffold extending from the first anchoring ring to the second anchoring ring. The second filter element may extend from the second anchoring ring upstream to the access port. The second filter element may extend transversely across the lumen of the first filter element at a plurality of axial locations.
