Abstract
Various exemplary drive apparatuses and associated methods are disclosed for driving an elongated member, e.g., a guidewire or catheter. An exemplary drive apparatus for driving an elongated member may include a rotational component configured to apply a torque to the elongated member, where the rotational component is positioned a first distance away from an insertion site along the elongated member. The drive apparatus may further include a rotational support configured to apply an assistance torque to the elongated member. The rotational support may be positioned a second distance from the rotational component along the elongated member that is larger than the first distance.
