1. A method for delivering an anchor for use in a gastric reduction system for reducing the cross-sectional area of a gastrointestinal lumen, comprising:

  • providing a delivery catheter having a needle translatably disposed therein, a distal end, a stabilization device disposed at the distal end and one or more anchors disposed within the needle, with at least one of the anchors comprising a sleeve of braided material and an eyelet for attaching the anchor to a suture;

    advancing the delivery catheter into the gastrointestinal lumen;

    engaging the stabilization device to a tissue wall of the gastrointestinal lumen;

    advancing the needle through the tissue wall;

    ejecting an anchor from a distal tip of the needle, the anchor having a suture attached thereto;

    withdrawing the needle from the tissue wall whereby the suture is extended through the tissue wall; and

    translating a fastener over the suture whereby a tension force is created on the suture and a tissue fold is maintained in the tissue wall.
