Abstract
A medical device such as a catheter is described having a stiff, preferably metallic, proximal tube. The distal portion of the proximal tube may have a plurality of perforations or slots formed therein to increase its flexibility. This provides a smooth transition between the relatively stiff proximal tube and a more flexible distal polymeric tube.
