1. An implantable sealing device for closing an aperture in a vessel sidewall in a subject, comprising:

  • an annular puncture frame comprising a longitudinal axis, a plurality of proximal fingers coupled to a proximal end of the frame, and a plurality of distal fingers coupled to a distal end of the frame;

    whereinthe proximal and distal fingers extend radially outward from the longitudinal axis when the annular frame is in a non-constrained state; and

    the distal fingers can be moved to a constrained state pointing in a substantially axial direction for insertion through the aperture in the vessel sidewall and can self-extend to the non-constrained state, thereby pinching the vessel sidewall between the proximal and distal fingers; and

    a tubular sealing member comprising a distal end coupled to the puncture frame, the tubular sealing member comprising an open state that allows access to a lumen of the vessel via the aperture; and

    wherein the tubular sealing member can be moved to a sealed state to close the aperture in the vessel sidewall.
