1. An introducer sheath comprising:

  • an elongated outer sheath including a proximal end, a distal end, and an outer sheath wall extending from the proximal end to the distal end, the outer sheath wall extending circumferentially about a longitudinal axis of the outer sheath to an extent greater than 180° and

    less than 360°

    to define an outer sheath slot extending from the proximal end through the distal end, the outer sheath slot parallel to the longitudinal axis; and

    an elongated inner sheath including a proximal end, a distal end, and an inner sheath wall extending from the proximal end to the distal end, the inner sheath wall extending circumferentially about a longitudinal axis of the inner sheath to an extent greater than the difference between 360° and

    the circumferential extent of the outer sheath wall, and less than 360°

    to define an inner sheath slot extending from the proximal end through the distal end, the inner sheath slot parallel to the longitudinal axis,wherein the inner sheath is coaxially disposed within the outer sheath, the inner sheath rotatable relative to the outer sheath and configured to form an enclosed lumen when the outer sheath slot is not aligned with the inner sheath slot, and to form an open slot along the entire length of the introducer sheath when the outer sheath slot is aligned with the inner sheath slot.
