Abstract
The invention provides a device, assembly, and method for transoral endoscopic restoration of a gastroesophageal flap valve. The invention also provides a self-steering and self-closing tissue fixation device for tissue fixation, and an invaginator device for gripping and maneuvering tissue. The restoration device includes a longitudinal member arranged for transoral placement into a stomach, a tissue shaper carried on the longitudinal member that causes stomach tissue to assume a shape related to a gastroesophageal flap, and a tissue fixation device that maintains the shaped stomach tissue in a shape approximating a gastroesophageal flap. The tissue shaper may include a mold. The device may include the invaginator device for gripping and maneuvering esophageal tissue to aid restoration of the gastroesophageal flap, and may include the tissue fixation device.

4. A tissue fixation device comprising an elongated member having a first end portion and a second end portion, the first end portion terminating in a tissue-piercing end, and a connecting portion extending between the first and second end portions, the elongated member having an initial configuration before deployment and a final configuration after deployment that forms an interior perimeter holding together a fold of tissue enclosed within the perimeter, and the properties of the elongated member cause it to move from the initial configuration to the final configuration.

5. A tissue fixation device comprising an elongated member having a first end portion and a second end portion, the first end portion terminating in a tissue-piercing end, and a connecting portion extending between the first and second end portions, the elongated member having an initial stressed and distorted configuration that, as the portions beginning with the first end portion are deployed from a lumen by a force pushing on the second end portion, steers the elongated member into and through tissue proximate to the lumen and assumes a final configuration, wherein the elongated member forms an interior perimeter holding together tissue enclosed within the perimeter.

48. A self-closing tissue fixation device for effecting tissue geometry, the device comprising:
-
an elongated member having a first end portion and a second end portion, the first end portion terminating in a tissue-piercing end; and
a connecting portion extending between the first and second end portions, the connecting portion having a first and second joining portions separated by a pressure portion, the elongated member having an initial stressed and distorted configuration that, as portions beginning with the first end portion are deployed from a lumen by a force pushing on the second end portion, steers the elongated member into and through tissue proximate to the lumen and assumes a final configuration, wherein the elongated member forms an interior perimeter holding together the tissue enclosed within the perimeter. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56)

-
a tissue fixation device comprising a tissue fixation device for effecting tissue geometry, the device comprising a first end portion and a second end portion, the first end portion having a tissue-piercing end, and a connecting portion extending between the first and second end portions, the device having an initial configuration before deployment and a final configuration after deployment that holds together tissue between the first and second portions; and
a tissue fixation device director including a lumen that slidingly receives the tissue fixation device and guides the tissue fixation device into tissue layers to be fixated. - View Dependent Claims (72, 73, 74)
