Flexible transoral endoscopic gastroesophageal flap valve restoration device and method

摘要

A transoral gastroesophageal flap valve restoration device has sufficient flexibility and dimension to be passed through the mouth, throat, and esophagus of a patient into the patient's stomach. The device includes a first member and a second member hingedly coupled to the first member. The first and second members are configured to flex in a direction to follow the esophageal path into the stomach and to be substantially rigid when forming the restored gastroesophageal flap valve.

主权项

1. An assembly for restoring a gastroesophageal flap valve, comprising:
a longitudinal member having an end arranged for placement in a stomach; a transoral gastroesophageal flap valve restoration device carried at the end of the longitudinal member and including an elongated body member, and an arm member hingedly coupled to the elongated body member, the elongated body member and arm member being arranged for esophageal passage into a stomach to receive stomach tissue there between to form a flap of a gastroesophageal flap valve; the elongated body member having a longitudinal tubular dimension and includes an outer tubular surface; the arm member being attached to the elongated body member by a hinge and pulley, the arm member being positioned radially outwardly relative to the outer tubular surface of the elongated body member and pivotable 180° relative to the elongated body member; the arm member having a distal end with a wing member extending transverse to a longitudinal axis of the arm member, the wing member having spaced apart openings to provide tissue reinforcement as fasteners are driven through the flap in tissue areas defined by the openings; and the elongated body member and arm member being configured to flex in a direction to follow an esophageal path into the stomach and to be rigid when receiving the stomach tissue there between and forming the flap of the gastroesophageal flap valve.
