ABSTRACT:
A thin-walled catheter of the type having a distal end adapted to be formed into a curve and guided through branching blood vessels or the like is provided with a two-layered tubular body portion having a rigid inner sheath and a flexible outer sheath, which may be radiopaque. The catheter exhibits excellent torque response and control while being especially thin-walled, thereby permitting minimization of the outer diameter size while providing excellent liquid flow rates therethrough and excellent strength properties. The tip portion is fuseless with respect to the rest of the catheter, the tip portion being an integral extension of the flexible outer sheath that is formed over a gap between lengths of the rigid inner sheath.
