1. A method of implanting a device having a main lumen and at least one side-branch lumen extending therefrom at a target location within a body of a patient, the target location having a main branch vessel and at least one side branch vessel in fluid communication with the main branch vessel, the method comprising:

  • advancing the device through a vasculature using a catheter, where the device is in a stretched state within the catheter having a reduced diameter;

    partially deploying a portion of the device from a first end of the catheter at the target location to position the main lumen of the device in the main branch vessel where a remainder portion of the device remains in the catheter while maintained in the stretched state;

    selectively tensioning the portion of the device to cause expanding and reducing of the portion of the device so that it can be repositioned;

    withdrawing the catheter relative to the device to expose the at least one side-branch lumen;

    guiding the at least one side-branch lumen into at least one side branch vessel using a second catheter while the side-branch lumen is in a stretched or tensioned state;

    adjusting the tension of the at least one side branch lumen independently of the main branch lumen using the second catheter to deploy the at least one side branch lumen; and

    fully deploying the device from the first end of the catheter by releasing the device from the stretched or tensioned state so that the device expands against the main branch vessel and side branch vessel to form a seal with the wall of the vessel.
