1. A catheter for puncturing a blood vessel wall, the catheter comprising:
a proximal portion;
a distal portion configured to be intravascularly positioned within a blood vessel, the distal portion comprising—
a first region extending distally from the proximal portion, wherein a portion of an outer surface of the catheter along the first region defines a transition surface at an angle away from a longitudinal axis of the catheter,
a second region extending distally from the first region, wherein a portion of the outer surface of the catheter along the second region forms a supporting surface that is substantially parallel to the longitudinal axis of the catheter and configured to contact an inner surface of the blood vessel wall, and
an exit port along the transition surface and spaced apart from the supporting surface along an axis transverse to the longitudinal axis of the catheter,
wherein the transition surface spaces the supporting surface away from the outer surface of the catheter along the axis transverse to the longitudinal axis of the catheter; and
a catheter lumen extending from the proximal portion to the exit port at the distal portion, wherein the catheter lumen and the exit port are configured to direct a tissue manipulation device through the exit port along a path substantially parallel with the longitudinal axis of the catheter to puncture the blood vessel wall.
