Claim 14:
15. The system of claim 12, wherein the multi-component tubular system comprises:
a first catheter having a steerable distal end portion, and comprising a first coupling at a longitudinal site of the first catheter, configured to be advanced transluminally into a subject; and
a second catheter having a steerable distal end portion configured to be advanced through the first catheter in any rotational orientation of the second catheter with respect to the first catheter, and to be advanced out of a distal end of the first catheter, the second catheter comprising a second coupling at a longitudinal site of the second catheter, the second coupling being configured to be advanced through the first catheter to the first coupling, and to be automatically intracorporeally locked to the first coupling upon the second catheter assuming a given rotational and longitudinal alignment with respect to the first catheter, the first coupling and the second coupling defining a distal locking mechanism having:
an unlocked state in which the first coupling is not locked to the second coupling, and in which the second catheter is rotatable and longitudinally slidable within the first catheter, and
a locked state in which the first coupling is locked to the second coupling, and in which the longitudinal site of the second catheter is (1) inhibited from rotating with respect to the longitudinal site of the first catheter, and (2) longitudinally slidable with respect to the longitudinal site of the first catheter.
