<P>PROBLEM TO BE SOLVED: To provide a medical catheter in which tensile strength and elongation exerting an influence on pressure resistance and dimensional stability are sufficiently controlled. <P>SOLUTION: The medical catheter includes an inorganic crystal composite material obtained by inluding an inorganic crystal in a polymer. As the inorganic crystal, a layered crystal is preferable, for instance, montmorillonite, synthetic mica, saponite, hectorite, sepiolite, or the like is preferable. As the polymer, polyamide or the like is preferable. As the medical catheter, a balloon catheter with a balloon is preferable. <P>COPYRIGHT: (C)2009,JPO&INPIT |
