Abstract:
1. 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.
