ABSTRACT:
A catheter is formed from a single extrusion of cold crystallizable material in its amorphous state. Selected portions of the catheter are subsequently subjected to the material's cold crystallization temperatures for a selected period of time in order to transform those portions into a more crystalline form. Increased crystallinity profoundly affects the physical characteristics of the material. A jointless catheter having a relatively stiff body and a soft, pliable, and atraumatic tip is thereby provided.
