1. A method of sealing a tissue puncture in an internal tissue wall accessible through a percutaneous incision, comprising:
- providing a tissue puncture closure device comprising a carrier tube with a filament extending therethrough, an insertion sheath, an anchor, and a sealing plug, the filament connected at a distal end of the carrier tube to the anchor, the anchor seated in a multi-level nest disposed in the carrier tube, the filament also connected to the sealing plug, the sealing plug being located proximal of the anchor for disposition and anchoring about the tissue puncture, wherein the multi-level nest comprises;
a first surface contacting the anchor;
a second surface spaced from the anchor in a direction radially inward relative to the first surface when the anchor is in an undeployed position;
wherein the first surface and the second surface are part of an outer surface of the carrier tube;
inserting the tissue puncture closure device into the percutaneous incision;
deploying the anchor into the tissue puncture by advancing the anchor at least partially out of a distal end of the insertion sheath followed by inserting a portion of the insertion sheath between the anchor and at least one of the first and second surfaces of the multi-level nest to rotate the anchor into a deployed position;
withdrawing the closure device from the percutaneous incision; and
tamping the sealing plug toward the anchor.

Abstract
The present invention provides a method and apparatus for sealing a subcutaneous tissue puncture. The method and apparatus increases the reliability of device function by creating a multi-level anchor nest in a carrier tube of a tissue puncture closure device. The multi-level nest allows an insertion sheath or other deployment member to slide between the carrier tube and the anchor to rotate and deploy the anchor within an artery or other lumen.
