<p>A device (10) for promoting hemostasis in a blood vessel puncture is employed with an introducer (12) that accesses the puncture through an incision (14). The introducer (10) has an open distal end (22), an open proximal end (28), and an axial channel (26) therebetween. The device (10) includes a hollow catheter (32) dimensioned to pass through the introducer channel, and having a distal end (34) to which is attached an expansible compression element that may be an inflatable balloon (42), a collapsible prong assembly (66), or a resilient foam pad (74). The compression element is collapsed when the distal end of the catheter is enclosed within the introducer. The device preferably includes a locating member which may be either a guide wire (78), or a hollow tube (30) with a locating balloon (50). A dissolvable locating tip element (140) connected to the distal end of the catheter, and may also be used to maintain the position of the device.</p> |
