The present invention is a catheter which is characterized by the fact that a pliable tip portion is formed at one end of a non-porous PTFE tube as an integral part of said non-porous tube, said tip portion being expanded so that the structure of said tip portion is converted into a porous structure, thus making said tip portion more pliable than the aforementioned non-porous tube. As a result of the aforementioned porous tip portion being formed at one end of the aforementioned non-porous PTFE tube, damage to the interior walls of the heart or blood vessels, etc., by the tip of the catheter is prevented. |
