Abstract:
An endoluminal device sized to be deployed within a first lumen comprising a restricted section having an inner surface with an inner diameter and a bifurcation into branch lumens each having an inner surface with an inner diameter, the restricted section inner diameter being smaller than a sum of the branch lumen inner diameters, the device comprising a proximal main tubular portion to be retained within a proximal portion of the first lumen and having a first diameter and two tubular limbs depending from the proximal main tubular portion, each limb having a second diameter and a distal end portion for deployment inside one of the branch lumens against the branch lumen inner surface, the distal end portion defining a third diameter larger than the second diameter, wherein the sum of the two second diameters is sized to be less than the restricted section inner diameter and each tubular limb comprises a trumpet-shaped, concave transition portion having a curved slope extending from the second diameter to the third diameter when viewed in longitudinal section in a non-deployed configuration, the end portion having a defined length comprising the third diameter.
