A device for promoting hemostasis in a blood vessel puncture is employed wit h an introducer that accesses the puncture through an incision. The introducer has an open distal end positionable at the puncture, an external portion wit h an open proximal end, and an axial channel therebetween. The device includes a hollow catheter, dimensioned to pass through the introducer channel, having a distal end to which is attached an expansible compression element, which may be an inflatable balloon, a collapsible prong assembly, or a resilient foam pad. Pressure is applied to the compression element through the introducer t o promote hemostasis by the compression of subcutaneous tissue adjacent the puncture. The device preferably includes a locator member passing through th e catheter and into the blood vessel through the puncture. The locator member may be either a guide wire, or a hollow tube with a locating balloon, dispos ed near the portion of the tube insertable into the vessel. |
