ABSTRACT:
An intravascular flexible catheter of the type having an inner tubular member defining a lumen, an outer tubular member surrounding the inner tubular member, and a metallic support member situated between the tubular members to provide rigidity to the flexible catheter. In the preferred embodiment the support member comprises a stainless steel wire braid which has been tempered or hardened to give it a significantly higher tensile strength than the prior art annealing process. This higher tensile strength affords significantly greater kink resistance to the flexible catheter as the lumen size is increased and the wall thickness is decreased.
