Thromboresistant coatings for aneurysm treatment devices

A device for insertion into a blood vessel lumen for treatment of an aneurysm, the device comprising:

• a generally cylindrical section comprising:
• a plurality of struts forming interstitial gaps between the plurality of struts,
• a proximal face, and
• a distal face,
• wherein the generally cylindrical section at least partially defines a device lumen extending in an axial direction from the proximal face towards the distal face, and
• wherein the device lumen is configured to allow blood flow through the device;
• and
• a proximal tapered section comprising a plurality of struts extending from a perimeter of the proximal face to a proximal apex, the proximal apex being radially aligned with the perimeter of the proximal face or being positioned radially outside of the perimeter of the proximal face, each of the plurality of struts of the proximal tapered section extending from a different point on the perimeter of the proximal face in a direction along the perimeter and towards the proximal apex such that none of the plurality of struts cross through a cross-sectional area defined by a proximal face of the device lumen;
• wherein one or more of the plurality of struts of the proximal tapered section are inverted within the proximal tapered section such that one or more of the inverted struts bend radially outward of the perimeter of the proximal face such that the proximal apex is positioned radially outside the perimeter of the proximal face.
