Surgical probe or catheter

摘要

A surgical probe or cathether (100) is completely enclosed in the end part (304) of a flexible tube (300). This end part has a closed distal end (301) which is folded back inside the remaining part of the flexible tube. A liq. at pressure is applied to the flexible tube and flows between the outer wall and the inner wall formed by the folding inwards of the end part. The pressure of the liq. then presses the inner walls together to form a sealed distal end (308).
