Abstract
This invention features a device (1) comprising: at least one radially expansible segment (7, 8) with, in the expanded state, a transversal cross section substantially greater than the transversal cross section of one of the secondary ducts (3); one segment (6) with, in the expanded state, a truncated shape, corresponding to the shape of the bifurcation at the flared transition zone (11) which separates the main duct (2) from the secondary ducts (3), and a flexible link (9) between these two segments (6, 7), enabling their adjustment relative to each other, according to the orientation of the secondary duct (3) receiving the radially expandable segment (7) relative to the flared transition zone (11).
