Abstract
Abstract A catheter employs an inner guide with a pre-formed distal tip, an outer guide with a predetermined deflection location, and a proximal actuator. The inner guide can be longitudinally extended and axially rotated relative to the outer guide. The proximal actuator can adjustably change a bend angle of the predetermined deflection location. The catheter can be deployed with the inner guide retracted inside the distal end of the outer catheter. The extensible and rotatable inner catheter can be combined with the adjustable bend angle of the outer guide to provide an improved system for accessing and cannulating venous structures.
