A device, system and method for improving delivery of hemostatic material, in which the device includes a vent cap body capable of removably engaging a cannula. The vent cap has a passage extending through the vent cap body from the cannula to an exterior of the vent cap body where a restricter for restricting the flow of fluid from the cannula to the exterior. In one embodiment, the vent cap has a valve which has an opened and closed position. In the closed position, the valve is designed to provide a back pressure or resistence. When a certain force is applied against the valve, the valve moves from the closed position to the opened position, where a gas or fluid may pass through the vent cap. The vent cap is designed to help maintain the continuity of the hemostatic material during delivery of the material from the adaptor to the trial staging chamber.
