[57] ABSTRACT
An intravascular delivery device (10) for inserting and withdrawing a thin, elongate probe (12) through a catheter (14). The delivery device (10) includes a fitting (18) connected to a flexible guide tube (15) and a delivery assembly (20) comprising a fixed inner sleeve (22) and a slidable outer actuator sleeve (24). The fitting (18) has an internal axial bore into which a seal (28) is placed. The seal (28) has a cone-shaped forward end (31) and an internal axial bore through which the cable (11) slidably passes. The outer sleeve (24) has its proximal end (26) affixed to the larger cable insulation (17) that is joined to the sheath (16) of the cable (11). A first ring (38) affixed to the cable (11) and a second ring (40) affixed to the proximal end (36) of the inner strain relief sleeve (22) cooperate to limit movement of the outer actuator sleeve (24) as it is slid over the inner strain relief sleeve (22) away from the fitting (18). A side port (42) depends from the fitting (18) to allow fluid into and out of the guide tube (15) and the catheter (14). In addition, a contamination sleeve (62) may be fitted over the delivery assembly (20).
