A catheter introducing system (10) includes an introducer catheter (12) comprising a flexible sheath (16) having a hemostasis valve (18) and an obturator (14) having a steering mechanism operated by a proximal actuator handle (22). The catheter introducer system will usually be introduced with the obturator inside of the flexible sheath so that the obturator can effect steering by laterally deflecting the distal end of the combined sheath and obturator. Such catheter introducing systems are particularly useful for large diameter sheaths which are not readily introduced over guide wires. A first exemplary hemostasis valve comprises a compressed foam insert having an axial lumen therein. A second exemplary hemostasis valve comprises an elastomeric insert which receives and seals over the catheter. <IMAGE>
