Abstract
Apparatus and methods are provided for forming a gastrointestinal tissue fold by engaging tissue at a first tissue contact point and moving the first tissue contact point from a position initially distal to, or in line with, a second tissue contact point to a position proximal of the second contact point, thereby forming the tissue fold, and extending an anchor assembly through the tissue fold from a vicinity of the second tissue contact point. Adjustable anchor assemblies; as well as anchor delivery systems, shape-lockable guides and methods for endoluminally performing medical procedures, such as gastric reduction, treatment of gastroesophageal reflux disease, resection of lesions, and treatment of bleeding sites; are also provided.

10. Apparatus for performing a medical procedure within a hollow body organ of tortuous or unpredictably supported anatomy, the apparatus comprising:
-
an overtube having a flexible state that facilitates insertion of the overtube into the hollow body organ, and a rigid state wherein the overtube resists bending forces exerted on the overtube;
a mechanism selectively operable to reversibly transition the overtube between the flexible and rigid states; and
a device adapted to form tissue folds within the hollow body organ, wherein the device may be advanced through the overtube while the overtube is disposed in the rigid state in any desired configuration within the unpredictably supported anatomy. - View Dependent Claims (11)

12. Apparatus for performing a medical procedure within a hollow body organ of tortuous or unpredictably supported anatomy, the apparatus comprising:
-
a main body having a flexible state that facilitates insertion of the main body into the hollow body organ, and a rigid state wherein the main body resists bending forces exerted on the main body;
a mechanism selectively operable to reversibly transition the main body between the flexible and rigid states while the main body is disposed in any desired configuration; and
a device coupled to a distal region of the main body, wherein the device is adapted to form tissue folds within the hollow body organ. - View Dependent Claims (13)

14. Apparatus for plicating tissue within a hollow body organ of tortuous or unpredictably supported anatomy, the apparatus comprising:
-
a guide tube;
a visualization device; and
at least one therapeutic device, wherein the visualization device and the at least one therapeutic device are configured for passage through the guide tube. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for performing a medical procedure within a hollow body organ of tortuous or unpredictably supported anatomy, the method comprising:
-
advancing an overtube within the hollow body organ in a flexible state;
transitioning the overtube to a rigid state in any desired configuration;
advancing a plication device through the overtube; and
forming a tissue fold within the hollow body organ with the plication device. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
