摘要：
A catheter assembly includes a catheter hub (12) defining an interior cavity(24) and acatheter tube (14) extending distally thereof. A rigid actuator (16) extendsproximally in theinterior cavity (24) and supports a seal member (18) thereon. The seal member(18) includesa central membrane (72), a distal portion (74), and a proximal portion (76).An hourglassshaped actuator cavity (88) is formed in the distal portion (74) and receivesa barbed end (50)of the actuator (16). The outer surface (71) of the seal member (18) is inpartialcircumferential engagement with the catheter hub (12) to define an air path(102) that allowsfluid communication between areas (PI and D1) of the interior cavity (24)distal and proximalof the seal member (18). A punch tool (160) is provided to form a tri-slit(82) in themembrane (72) of the seal member (18). The seal member (18) may be configuredfor multi-use and include a biasing member (204) that moves the seal member (18) toforce themembrane (72) back over the actuator (16) to close the membrane (72).
