Catheter and medical tube

Abstract

A catheter is made of a melt-extruded polymeric material consisting of non-polyvinyl chloride. The catheter has a loss tangent not less than 0.15, when the dynamic viscoelasticity thereof is measured at 25° C. in a longitudinal vibration thereof. The catheter has a kinking resistance not less than 25 mm, when the catheter having a length of 70 mm is used under a dry condition at room temperature. A medical tube is made of a polymeric material consisting of nonpolyvinyl chlorides. The medical tube consists of a compound of two or more kinds of polymeric materials. The medical tube has a loss tangent not less than 0.15, when the dynamic viscoelasticity thereof is measured at 25° C. in a longitudinal vibration thereof. The medical tube has a kinking resistance not less than 25 mm, when the medical tube having a length of 70 mm is used under a dry condition at room temperature.
