ABSTRACT:
A seal for a medical device such as a catheter is formed between two parts of the device which are capable of movement relative to each other, either axially, rotationally or both. The seal is formed by opposing sealing surfaces on each of the two parts, the surfaces being sufficiently smooth and of sufficiently close proximity that liquids having viscosities on the order of those normally used in catheters will not pass between the surfaces due to such effects as surface tension and friction. In certain embodiments, the surfaces are arranged to permit liquid to pass at a controlled rate for purposes of perfusion when desired, or the surfaces can be moved relative to one another to achieve this capability.
