1. An endograft implant, comprising:

  • a tubular implant body comprising an elastic end and an implant lumen, the elastic end comprising a sealable circumferential collar having a diameter;

    a variable sealing device contained within the sealable circumferential collar, the variable sealing device being operable to reversibly vary the diameter of the sealable circumferential collar;

    a control lead releasably, directly, and mechanically connected to the variable sealing device for reversibly varying the diameter of the variable sealing device when the control lead is rotated and;

    a plurality of retractable retention tines pivotally mounted within the variable sealing device such that, when the control lead is rotated to expand the diameter of the sealable circumferential collar, the retractable retention tines are exposed outwardly from the variable sealing device to engage an anatomic lumenal wall adjacent the elastic end and, when the control lead is rotated to reduce the diameter of the sealable circumferential collar, the retractable retention tines withdraw inwardly into the variable sealing device.
