  "abstract": "Apparatuses, systems, and methods are disclosed for regulating an eversion process in everting sheath systems to avoid uncontrolled deployment of the sheath. The sheath system includes a reel and a sheath stored thereon, where the sheath is capable of everting from a retracted position to an extended position as the reel rotates about a rotational axis. The rotational characteristics of the reel are controlled by a torque mechanism operable to directly or indirectly apply a passive torque to the reel to adjust a rate at which the sheath is released from the reel as the sheath everts from the retracted position to the extended position.",
