A steerable guide catheter includes a tip ring at a distal end and one or more pullwires configured to engage with the tip ring when put in tension, the pullwire(s) thereby subjecting the steerable guide catheter to a curving or turning force. The tip ring includes a saddle and one or more pullwire channels allowing the pullwire to be looped over the saddle such that when the pullwire is placed under tension, it abuts against the saddle of the tip ring. Some embodiments include additional catheters axially aligned within or outside of the steerable guide catheter, and include a keying feature aligning the rotation of the multiple catheters. The keys of the keying feature can be formed of a polyamide with a glass microsphere filler, and can be thermally welded to the catheter.
