Abstract
A system for treating aortic dissection including an aortic dissection implant comprising an expandable anchoring structure and an elongate tubular structure. The expandable anchoring structure can be configured to apply radial force to the sinuses of the aortic root and/or the sinotubular junction when expanded. The elongate tubular structure can comprise an expandable support frame and one or more layers. The expandable support frame can be configured to extend from the descending aorta to the ascending aorta and curve along with a curvature of the aortic arch when expanded within the aorta. The one or more layers can comprise a first porous layer comprising an atraumatic outer surface positioned over the expandable support frame and a second non-porous layer positioned over a portion of the first porous layer. The second non-porous layer may be configured to be positioned on opposite sides of the aortic dissection and to be inflatable via blood flow to seal against the dissection.
