Zusammenfassung:	CATHETER ASSEMBLY WITH SEAL MEMBER A catheter assembly comprising a catheter hub (12) having an open proximal end (20) and a distal end (22) defining an interior cavity (24) therebetween, with a catheter tube (14) extending distally from the catheter hub distal end (22); a rigid actuator (16) extending proximally in the interior cavity (24) of the catheter hub (12) from the catheter hub distal end (22) to a free end (51), the actuator (16) having an enlarged proximal flange (56) at the free end (51) thereof; and a seal member (18) disposed in the interior cavity (24) of the catheter hub (12), wherein the seal member (18) includes a membrane (72) and a distal portion (74) extending distally from the membrane (72) to a sealing outlet bore (86), the distal portion (74) having an actuator cavity (88) therein between the membrane (72) and the sealing outlet bore (86), the actuator cavity (88) having a narrowed portion (89) defining an hourglass shape thereto, the actuator (16) extending through the sealing outlet bore (86) into the actuator cavity (88) with the proximal flange (56) engaged against the narrowed portion (89) of the actuator cavity (88).
