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.

[What is claimed is:] [1.]an adaptor comprising:an elongated member having a first end, a second end, and a lumen extending from the first end to the second end allowing passage of fluid through the adaptor;a fitting provided at the second end for connection to a cannula; anda tapered section of the lumen tapering from a first diameter at the first end to a second diameter at the second end which is smaller than the first diameter such that a dry sponge pledget having a width larger than the second diameter is compressible when hydrated to allow passage of the pledget into the second diameter; anda transparent visualization chamber connectable to the fitting provided at the second end of the elongated member.
