Patent ID: 7540879

Claim:
Endolumenal device for delivering and deploying an endolumenal expandable prosthesis at a bifurcation provided with a main conduit and at least a secondary conduit, comprising: an elongated body having a proximal end portion and a distal end portion; the distal end portion of said elongated body comprising an expandable portion having a proximal end and a distal end, the expandable portion engageable with the endolumenal expandable prosthesis and adapted to adjust said prosthesis from a radially collapsed condition to a radially expanded condition; a guidewire tracking device at least partially extending along said elongated body; wherein said expandable portion being longitudinally associated to the elongated body in order to expand said prosthesis eccentrically from one side with respect to the elongated body, and said guidewire tracking device comprises at least a guidewire lumen at least partially extending inside said elongated body, having a plurality of guidewire distal ports comprising a first guidewire distal port and a second guidewire distal port, the first guidewire distal port and the second guidewire distal port being in communication with the same lumen and opening to an outside of the endolumenal device to be in fluid communication with a blood vessel in use, said first guidewire distal port provided on a side of the elongated body opposed to the expandable portion and suitable for slipping through it a guidewire portion of at least a guidewire placeable with its distal portion in said main or at least a secondary conduit, said second guidewire distal port provided on a side of the elongated body opposed to the expandable portion for slipping through it a guidewire portion; wherein each of the first guidewire distal port and the second guidewire distal port is located between the proximal end and distal end of the expandable portion.
