A device for providing or enhancing hemostasis at a vascular puncture site disposed at the distal end of a tissue tract comprises a shaft having a non-compliant surface at its distal end. The non-compliant surface is oriented at an angle which allows it to lie flat over tissue puncture when the tissue tract is oriented obliquely, e.g., as the result of the Seldinger catheter introduction technique. The device may be used by itself or in combination with suturing of the vascular puncture, where the device enhances hemostasis and prevents blood leakage through the primary suture closure.

[ What is claimed is:] [1.] A method for occluding a puncture of a blood vessel at the end of a tissue tract, said method comprising:applying pressure without applying heat directly to an adventitial surface of the blood vessel with a surface which is engaged against the adventitial surface, wherein a force in the range from 5 g to 50 g is applied over an area in the range from about 6 mm.sup.2 to 30 mm.sup.2 for a time in the range from about 10 minutes to 24 hours, the pressure applied at least in part by tensioning a member, the member selected from the group consisting of suture and a guidewire, and anchoring the member to a shaft which extends out the tissue tract from the surface, the force being transferred along the shaft and to the surface from outside the tissue tract; andremoving the shaft with the surface through the tissue tract after applying the pressure.
