1. A sealable vascular endograft system for placement in a vascular defect, comprising:

  • an elongated implant delivery catheter having a catheter proximal end and a catheter distal end and shaped to be disposed within a blood vessel having internal walls, the implant delivery catheter including;

    an implant delivery catheter sheath defining an implant delivery catheter lumen; and

    an endovascular implant removably disposed within the implant delivery catheter lumen in a compressed or folded state for delivery thereof to the vascular defect, the endovascular implant including;

    a tubular implant body; and

    a sealable circumferential collar at the tubular implant body and including;

    a variable sealing device; and

    a control lead traversing from the variable sealing device to a user and controlling variability of the variable sealing device by the user, the variable sealing device and the control lead cooperating to reversibly expand and contract the sealable circumferential collar such that the sealable circumferential collar circumferentially adjusts during deployment thereof to achieve a repositionable fluid-tight seal between the sealable circumferential collar and the internal walls of the blood vessel.
