An instrument for achieving rapid hemostasis at the conclusion of a catheterization procedure comprises a device for injecting a fluid hemostatic agent into a puncture wound that is operatively associated with a conventional introducer sheath component of the introducer used to gain access to a blood vessel using the Seldinger technique. The hemostatic agent injection device includes a tubular member that can be concentrically disposed with a tubular introducer sheath so as to be slidable therealong and where the injection device includes a hemostatic agent inlet port at a proximal end thereof and an ejection port at a distal end, the two ports being interconnected by a lumen. In a first embodiment, the hemostatic agent injection device is adapted to coaxially surround the introducer sheath and in an alternate embodiment, the injection device is coaxially disposed within the lumen of the introducer sheath.

[ What is claimed is:] [1.] A device for sealing percutaneous punctures in a blood vessel, comprising:(a) an elongated tubular member having a proximal end, an outwardly flared distal end portion and a working lumen extending therebetween, the elongated tubular member further including an injection lumen leading to at least one injection outlet port in the flared distal end portion; and(b) a hub affixed to the proximal end of the elongated tubular member, the hub having an injection inlet port in fluid communication with the injection lumen adapted to transport a fluid hemostatic agent to said at least one injection outlet port and a bore aligned with the working lumen, with the bore and the working lumen dimensioned to receive a tubular vascular introducer sheath therethrough with the tubular introducer sheath being slidable relative to the elongated tubular member.
