1. An active introducer sheath system including:
a handle comprising a translation mechanism including:
a rotating nut threadably engaged with the handle and axially movable along the handle upon rotation; and
a sheath comprising a cylindrical structure including:
a fixed rod, a proximal portion of the fixed rod fixedly attached to the handle;
a mobile rod, a proximal portion of the mobile rod attached to the translation mechanism such that rotation of the rotating nut moves the mobile rod in an axial direction;
wherein the fixed rod and the mobile rod are coupled such that activation of the translation mechanism causes the mobile rod to move axially with respect to the fixed rod, thereby changing a diameter of the cylindrical structure from a first diameter to a second diameter, wherein the second diameter is different from the first diameter.
