ABSTRACT:
Catheter for insertion into the cardiovascular system, and method of manufacturing the same. A helically wound ribbon of flexible material is imbedded in the wall of the catheter to provide a torsional rigidity which facilitates steering and turning of the catheter during emplacement. The stiffness of the catheter is controlled by varying the pitch of the helically wound ribbon.
