Abstract
A closed system suction catheter assembly has an aspirating catheter with a radially-projecting portion or flanges at its distal end. The catheter extends through a patient connecting member which is internally shaped to cooporate with the projection on the catheter so that, when the catheter is pulled proximally to its full extent, the projections seal within the patient connecting member.
