1. A percutaneous access system for providing minimally invasive access, comprising:

  • an access sheath comprising an elongate tubular body that defines a lumen, at least a portion of the elongate tubular body being expandable from a first, folded, smaller cross-sectional profile to a second, greater cross-sectional profile, the access sheath having a distal end and a proximal end, the proximal end comprising an sheath hub, the sheath hub including an anti-rotation member;

    a releasable jacket carried by the access sheath to restrain at least a portion of the elongate tubular structure in the first, folded, smaller cross-sectional profile; and

    an expandable member positioned within the elongate tubular body and configured to expand the elongate tubular body from the first, smaller cross-sectional profile to the second, greater cross-sectional profile, the expandable member having a distal end and a proximal end, the proximal end including an expandable member hub with a complementary anti-rotational member configured to mate with the anti-rotational member of the sheath hub and limit rotation between the access sheath and the expandable member.
