Abstract
A tissue puncture locator device includes an anchor assembly and a sealing member. The anchor assembly includes an anchor portion, a tube portion, and a filling member. The anchor portion is positioned at a distal end of the tube portion and configured for placement through a vascular incision into a vessel. The anchor member has an unexpanded configuration that permits passage through the vascular incision and an expanded configuration that limits passage through the vascular incision. The filling member is retained in the tube portion and adapted for insertion from the tube portion into the anchor member to provide the expanded configuration, and adapted for retraction from the anchor member into the tube portion to provide the unexpanded configuration. The sealing member is configured for placement adjacent the vascular incision outside the vessel.
