Abstract
An access port closure valve for use with a respiratory support system is provided. The access port closure valve has a sealing member that has a first and second sealing lip. The sealing lips are elongated and are parallel to one another. The sealing lips are at least partially cylindrical in shape and are urged against one another to form a seal that has a taper. An elongated cylindrical frame substantially surrounds the sealing member. The sealing lips are disposed transversely across an end of the frame. The frame is configured to engage the respiratory support system. The sealing member seals the frame and accommodates passage of a surgical instrument through the valve.
