    摘要： The present invention provides methods and apparatus for endoluminally performing gastroplasty. In one variation, the apparatus comprises a sizing tube, and a steerable guide that may be reversibly disposed within the sizing tube. In another variation, the sizing tube and steerable guide are integrated into a single device. In one method of utilizing the apparatus, a pouch is endoluminally formed within a patient's stomach, thereby partitioning or reducing the stomach and restricting the flow of food therethrough. The pouch may form a Vertical Banded Gastroplasty or Magenstrasse and Mill in an endoluminal fashion. Advantageously, the sizing tube or steerable guide may be used to properly size the endoluminal pouch.

    摘要： Apparatus & methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

    摘要： Flexible tubular liner coating systems are described herein. A method for coating and forming the flexible tubular inner liner may comprise, in one example, coating at least a first surface of a flexible elongate strip having a first and a second edge and then bringing the first and second edges of the flexible elongate strip into proximity of one another. Once the edges are brought towards one another, they may be joined such that a flexible tubular liner is formed having the coated first surface formed as an inner surface of the flexible tubular liner.
