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.

Claims12

Dependent claims

Apparatus for performing a medical procedure on a body organ comprising:

an overtube having a flexible state and a rigid state;
a mechanism selectively operable from outside the body organ to reversibly transition the overtube between the flexible and rigid states;
a flexible tube with a distal end configured for insertion through the overtube and into the body organ;
a tissue engaging assembly on the distal region of the flexible tube;
and
an anchor delivery system comprising a flexible delivery catheter having a proximal portion and a bending section, with the bending section movable from a first position where the bending section is generally aligned with a longitudinal axis of the proximal portion of the flexible delivery catheter, to a second position where the bending section is generally transverse to the longitudianl axis of the proximal portion of the flexible catheter;
with a distal end of the flexible delivery catheter directly connected to the distal end of the flexible tube via a pivoting link;
and
a needle movable from a first position where the needle is substantially completely retained within the flexible delivery catheter, to a second position where a distal portion of the needle extends from the distal end of the flexible delivery catheter.
