Abstract
A catheter system () with a valve assembly () that expels excess inflation fluid when a cuff or balloon () of the catheter system is overinflated. The valve assembly includes a luer-activated spool () biased toward a sealed condition, a precision relief/check valve () biased toward a scaled condition, a primary valve body outlet (), a valve body feedback inlet (), and a secondary valve body outlet (). An inflation lumen () is in fluid communication with the primary valve body outlet and an interior of the cuff or balloon. A feedback lumen () is in fluid communication with the interior of the cuff or balloon and the valve body feedback inlet. When feedback fluid builds up pressure in excess of the restoring force of the relief spring, the relief/check valve opens, unsealing an expulsion pathway and relieving excess fluid from the cuff or balloon.
