<p>A stent introducer (40) includes a hollow tube (42) having a proximal end (4 4) and a distal end (46) and a cup-like end cap (54) for covering the distal end (46). The cap (54) is coupled to a control member (4 8) which extends through the hollow tube (42). The proxi mal ends of the tube and the control member are coupled to an actuation device ( 56) for effecting relative movement of the tube (42) and control member (48) to move the cap (54) relative to the distal end (45) of the tube (42). The distal end of a stent (10) is inserte d into the cup-like cap (54) and the actuation device (56) is manipulated to move t he cap (54) and the distal end (46) of the tube (42) tog ether, thereby gripping the distal end of the stent (10). The introducer (40) is in serted into a sheath (70) and pulls the distal end of th e stent (10) into the sheath (70), thereby stretching it to its reduced diameter. Th e sheath (70) containing the stent (10) and the introduc er (40) is maneuvered to the site for deployment of the stent (10).</p> |
