Medical tubing and extrusion die for producing the same

摘要

A thin-walled medical tubing comprising an elongated hollow tubular body which is open at both ends and extends continuously therebetween has a filler-containing resin layer in which the filler is oriented in a substantially circumferential direction with respect to the hollow tubular body. The tubing has excellent maneuverability, including pushability, ability to transmit torque, trackability and kink resistance, enabling it to be used as a sheath or catheter.
