Abstract: 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.

Abstract: A system including an adaptor and a syringe is used for facilitating hemostasis of a biopsy tract or other puncture wound by delivery of an absorbable sponge in a hydrated state into the wound. The adaptor includes a tapered lumen for hydrating and compressing the relatively large absorbable sponge for delivery through a relatively small cannula, such as a biopsy needle. The hydrated absorbable sponge is injected through the biopsy needle into the biopsy tract by fluid. Alternatively, the sponge may be delivered to the biopsy needle by injection of fluid and then delivered to the biopsy tract by a plunger or stylet. The system may also include a trail staging chamber for inspecting a condition of the sponge before delivery. The implanted absorbable sponge facilitates hemostasis at the biopsy site or other puncture wound and minimizes the chance of internal bleeding. The absorbable sponge material is absorbed by the body over time.
