Device and method for facilitating hemostasis of a biopsy tract

A system for preparing and delivering a hydrated sponge to a cannula for delivery to tissue, the system comprising:

• 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;
• a fitting provided at the second end for connection to a cannula;
• and
• a 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;
• a transparent visualization chamber connectable to the fitting provided at the second end of the elongated member;
• and
• a removable vent cap configured to engage both the second end of the elongated member and a distal end of the transparent visualization chamber.

A method of facilitating hemostasis of a puncture wound by injecting a sponge through a cannula into the puncture wound, the method comprising:

• inserting a pledget of a sponge into an adaptor having a tapered lumen;
• connecting the adapter to a transparent visualization chamber and injecting the pledget from the adaptor into the visualization chamber;
• visually inspecting the pledget within the visualization chamber to determine a condition of the pledget;
• connecting the visualization chamber to a cannula;
• and
• delivering the pledget through the cannula to facilitate hemostasis of a puncture wound.
