<p>An endolumenal device for delivering and positioning an endolumenal expandable prosthesis for a bifurcation is provided. The endolumenal device includes a guidewire tracking device and an elongated body that has a central longitudinal axis and an expansion device configured to expand symmetrically relative to the central longitudinal axis. The guidewire tracking device comprises a single guidewire lumen (50) disposed within a wall structure of the expansion device. The guidewire tracking device has at least three distal ports extending through the wall structure of the expansion device. The guidewire lumen includes a distal apical port (114) in an approximately central position relative to the expansion device, considered in cross section at right angles to the central longitudinal axis.</p> |
