Abstract
An exemplary drive apparatus is disclosed having a roller assembly configured to impart axial motion to the elongate member along a first continuous surface configured to maintain contact with the elongate member during axial motion. The drive apparatus may further include a roller support configured to rotate the roller assembly, thereby imparting rotational motion to the elongate member. The roller support may be configured to rotate the roller assembly about a second continuous surface configured to maintain contact with the roller support during rotational motion. Moreover, the roller assembly and roller support may be configured to impart axial and rotational motion independently of one another, such that a first one of the roller assembly and the roller support imparts their associated motion regardless of a presence or absence of motion by the other of the roller assembly and the roller support.
