摘要：
The invention is direction to an alignment apparatus comprising a central sheath, an alignment sheath, and at least one stent. The central sheath and the alignment sheath each have a wall and a distal end where the wall of the alignment sheath is engaged to the wall of the central sheath. The wall of the central sheath defines a central lumen that has a central guide wire extending therethrough and the wall of the alignment sheath defines an alignment lumen that has an alignment guide wire extending therethrough. The distal end of the alignment sheath is positioned proximally to the distal end of the central sheath. The alignment apparatus has at least one stent disposed about one of the alignment guide wire or the central guide wire. The at least one stent has a pre-delivered state so that when the at least one stent is in the pre-delivered state, it is contained within at least one of the central sheath and the alignment sheath.
