Claim Text:
1. A device for moving a sheath retraction line relative to a catheter through which it at least partially extends, the device comprising: a housing connectable to the catheter; a mover associated with the housing and connectable to the sheath retraction line for moving the sheath retraction line relative to the housing and relative to the connected catheter; a pre-mover for effecting a pre-movement adjustment of the sheath retraction line connected to the mover relative to the catheter connected to the housing, to reduce slack between the sheath retraction line and the catheter in preparation for moving the sheath retraction line with the mover, to ensure direct subsequent relative movement between the sheath retraction line and the catheter by the mover, the pre-mover being configured to become inoperable following pre-movement adjustment of the sheath retraction line, wherein the housing forms a sealed unit in which the mover and pre-mover are mounted to be actuated by a user; and a limiter for limiting the extent of movement of the sheath retraction line relative to the catheter, wherein the limiter comprises a band of substantially inextensible material which is connected at one end to, and is wound on, a spool which is mounted to the housing, the band being connected at the other end to a winding member of the mover onto which the band is wound from the spool as the mover moves the sheath retraction line, thereby permitting movement of the mover until the band is fully unwound from the spool and thereafter preventing further movement of the sheath retraction line by the mover.
