Abstract
A system (2) includes broadly a catheter assembly (6) and a drive assembly (4). The catheter assembly includes a hollow sheath (20) housing a connecting element, typically a drive cable (22), with an operative element, such as a transducer (24), towards its distal end (26). The drive assembly is adapted to move the connecting element longitudinally within the hollow sheath. The drive assembly includes a main body (8) to which a proximal assembly, such as a rotary drive assembly (16), connected to the proximal end (28) of the connecting element, is mounted for longitudinal movement along the main body. The main body also has an anchor element (32) which is used to secure the sheath to the main body. A longitudinal drive motor (40) is carried by the main body and drives the proximal assembly along the main body.
