Abstract
A closed system suction catheter assembly has a catheter that is protected along its length by a flexible sleeve. The catheter extends through a patient connecting member by which the assembly is connected to a tracheal tube. Within the connecting member there is a sliding seal support with a groove in which is located a rib that extends along the outside of the catheter. The rib follows a sinusoidal path so that the catheter is twisted backwards and forwards as the catheter is pushed or pulled through the patient connecting member.
