Interlocking endoluminal device

A system for deployment of an endoluminal device, the system comprising:

• the endoluminal device comprising a first member having a first trunk portion, a first midsection comprising a first opening, and a first leg portion comprising a first aperture;
• and a second member having a second trunk portion, a second midsection comprising a second opening, and a second leg portion comprising a second aperture;
• a first introducer for deploying the first member into a body lumen and having a first profile;
• and
• a second introducer, having a second profile essentially identical to the first profile, for deploying the second member into the body lumen;
• wherein each of the first member and the second member comprises a stent having a covering inside, outside, or inside and outside of the stent, the device having an assembled configuration in which the first member and second member are interlocked with one another in a sealing relationship with the second trunk portion coaxially contained within, and sealed against, the first trunk portion, the second leg portion protruding through the first opening, and the second opening facing the first leg portion.

A method of deploying an endoluminal device in a deployment location in a branched lumen comprising a main lumen, a first branch lumen, and a second branch lumen, the endoluminal device comprising a first member comprising a first trunk portion, a first midsection comprising a first opening, and a first leg portion comprising a first aperture;

• and a second member comprising a second trunk portion, a second midsection comprising a second opening, and a second leg portion comprising a second aperture, each of the first member and the second member comprises a stent having a covering inside, outside, or inside and outside of the stent;
• the method comprising the steps of:
• (a) inserting a first introducer containing the first member into the branched lumen from a first proximal location;
• (b) deploying the first member with the first trunk portion in the main lumen and the first leg portion in the first branch lumen;
• (c) inserting a second introducer containing the second member into the branched lumen from a second proximal location;
• (d) deploying the second member such that the second member is interlocked with the first member in a sealing relationship with the second trunk portion coaxially contained within, and sealed against, the first trunk portion, the second leg portion protruding through the first opening into the second branch lumen, and the second opening facing the first leg portion.
