A hemostatic device for sealing a puncture of a vessel, said hemostatic device comprising: a housing comprising a proximal end and a distal end and defining a housing cavity therein, said housing cavity extending between said proximal end and said distal end; an outer tube carrier disposed within said housing cavity, said outer tube carrier moveable within said housing cavity between said housing distal and proximal ends, said outer tube carrier defining an outer tube carrier cavity; a first tube defining a first lumen configured to channel a fluid therethrough, said first tube coupled to said housing; a second tube extending from said housing distal end, said second tube housing at least a portion of the first tube and at least partially defining a second lumen configured to retain a hemocoagulant agent therein, said second tube coupled to said outer tube carrier and moveable therewith relative to said first tube between (i) a closed position configured to substantially retain the hemocoagulant agent within said second lumen when said outer tube carrier is positioned adjacent said housing distal end, and (ii) an open position configured to at least partially expose the hemocoagulant agent when said outer tube carrier is positioned adjacent said housing proximal end; a plunger carrier disposed within said outer tube carrier cavity, said plunger carrier moveable within said outer tube carrier cavity between said housing distal and proximal ends; a plunger coupled to said plunger carrier for movement with said plunger carrier, wherein said plunger is longitudinally moveable within said second lumen in response to movement of said plunger carrier within said outer tube carrier cavity; and an actuating member (400, 410) coupled to, and rotatable with respect to, said housing, said actuating member extending at least partially through said housing, said outer tube carrier and said plunger carrier coupled to said actuating member such that said plunger carrier and said outer tube carrier simultaneously move in opposite directions in response to rotation of said actuating member. a housing comprising a proximal end and a distal end and defining a housing cavity therein, said housing cavity extending between said proximal end and said distal end; an outer tube carrier disposed within said housing cavity, said outer tube carrier moveable within said housing cavity between said housing distal and proximal ends, said outer tube carrier defining an outer tube carrier cavity; a first tube defining a first lumen configured to channel a fluid therethrough, said first tube coupled to said housing; a second tube extending from said housing distal end, said second tube housing at least a portion of the first tube and at least partially defining a second lumen configured to retain a hemocoagulant agent therein, said second tube coupled to said outer tube carrier and moveable therewith relative to said first tube between (i) a closed position configured to substantially retain the hemocoagulant agent within said second lumen when said outer tube carrier is positioned adjacent said housing distal end, and (ii) an open position configured to at least partially expose the hemocoagulant agent when said outer tube carrier is positioned adjacent said housing proximal end; a plunger carrier disposed within said outer tube carrier cavity, said plunger carrier moveable within said outer tube carrier cavity between said housing distal and proximal ends; a plunger coupled to said plunger carrier for movement with said plunger carrier, wherein said plunger is longitudinally moveable within said second lumen in response to movement of said plunger carrier within said outer tube carrier cavity; and an actuating member (400, 410) coupled to, and rotatable with respect to, said housing, said actuating member extending at least partially through said housing, said outer tube carrier and said plunger carrier coupled to said actuating member such that said plunger carrier and said outer tube carrier simultaneously move in opposite directions in response to rotation of said actuating member.
