Apparatus including multiple invaginators for restoring a gastroesophageal flap valve and method
First Claim
1. A transoral gastroesophageal flap valve restoration assembly comprising:
- an elongated member having a distal end arranged for being fed down an esophagus in communication with a stomach;
a tissue shaper carried on the distal end of the longitudinal member, the tissue shaper comprising a first member adjacent the distal end of the elongated member and a second member, the first and second members being hingedly coupled to receive the stomach tissue to be shaped there between, the distal end of the elongated member having a tissue gripper that grips esophageal tissue oral of a Z line and the first member of the tissue shaper having a tissue gripper that grips stomach tissue aboral of the Z line; and
a tissue fastener that maintains the shaped stomach tissue.

Abstract
A transoral gastroesophageal flap valve restoration assembly comprises a pair of tissue grippers. The device comprises an elongated member having a distal end arranged for being fed down an esophagus in communication with a stomach and a tissue shaper carried on the distal end of the longitudinal member. The tissue shaper comprises a first member adjacent the distal end of the elongated member and a second member. The first and second members are hingedly coupled to receive the stomach tissue to be shaped there between. The distal end of the elongated member has one of the tissue grippers that grips esophageal tissue oral of a Z line and the first member of the tissue shaper has the other tissue gripper that grips stomach tissue aboral of the Z line. A tissue fastener maintains the Shaped stomach tissue.

17. A transoral gastroesophageal flap valve restoration assembly comprising:
-
an elongated member having a distal end arranged for being fed down an esophagus in communication with a stomach, the distal end of the elongated member having a plurality of tissue grippers that together grip both esophageal tissue oral of a Z line and stomach tissue aboral of the Z line;
a tissue shaper carried on the distal end of and hingedly coupled to the elongated member to cause stomach tissue to be shaped to be received between the elongated member and the tissue shaper when the tissue shaper hingedly pivots into engagement with the elongated member; and

25. A method of restoring a gastroesophageal flap valve associated with an esophagus, a stomach and a Z line that transitions esophageal tissue and stomach tissue, the method comprising the steps of:
-
concurrently gripping esophageal tissue oral of the Z line and stomach tissue aboral of the Z line;
axially translating the gripped tissue until the Z line is within an associated diaphragm; and
manipulating stomach tissue from within the stomach to restore the gastroesophageal flap valve. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
