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.
