Abstract
One aspect of the invention provides catheter pullback apparatuses in which a reusable drive component is enclosed in a sterile disposable barrier enclosure, such as a polymeric sheath/bag. In one embodiment, the reusable drive component includes a pullback carriage that is magnetically coupled, through the sterile barrier, to a slideable catheter shuttle adapted to retain a catheter hub of a catheter. In another embodiment, a sterile barrier-enclosed drive component is inserted into a housing, in which process a piercing tip provided on the catheter shuttle pierces the enclosure and mechanically mates the slideable catheter shuttle and pullback carriage. In this manner, non-sterility of the operating environment is minimized.
