A tubing assembly and method of manufacture for a catheter having an inner tubular member defining a lumen, an outer tubular member surrounding said inner member, and a braid mounted between the tubular members to provide rigidity to the flexible catheter. The braid preferably has different braid densities in selected regions along the length of the catheter. In addition, the outer tubular member preferably includes a number of segments each having different mechanical properties. In this configuration, both the polymer characteristics and the braid density may be independently varied along the length of the catheter to maximize catheter performance.
