Abstract: The disclosure is directed to a system for maintaining hemostasis during introducing or withdrawing an interventional device. The system includes a housing. The housing includes a first end, a second end and a side wall defining a housing chamber. The system also includes a first funnel-shaped member disposed at least partially within the housing chamber. The first funnel-shaped member includes an inner portion, a middle portion and an outer portion. The inner portion of the first funnel-shaped member includes an elastic orifice, which is aligned with the through channel of the housing. The first funnel-shaped member includes an open configuration and a closed configuration. When the first funnel-shaped member is in the closed configuration, the elastic orifice is substantially closed, and when the first funnel-shaped member is in the open configuration, an interventional device is introduced through the system and the elastic orifice is open.
