Abstract: A device having a support structure and a covering material, the device operable to be delivered to an at least partially occluded lumen including a non-bifurcated portion, a first bifurcated portion, and a second bifurcated portion, the device comprising a body including a primary portion, a first branch, and a second branch, the primary portion defining a primary lumen, the primary portion defined between a first open end and a flow divider, the first branch defining a first branch lumen, the first branch extending from the primary portion at the flow divider to a first branch open end, and the second branch defining a second branch lumen, the second branch extending from the primary portion at the flow divider to a second branch open end, the body having a radial wall strength sufficient to resist inward radial force and collapse of the primary, first branch, and second branch lumens.

Abstract: Techniques and features for reduction of air potentially released during endoluminal device (e.g., thoracic aortic stent-graft device) deployment. Also addressed are methods for quantifying efficacy of pre-treatment techniques and features for reducing said air. Such air reduction can help reduce risk of air embolization during device (e.g., implant, such as stent-graft) deployment which could potentially decrease the risk of negative effects from such embolization.
