Abstract
Surgical devices and methods used for invaginating tissue during, for example, an endoscopic fundoplication procedure, are disclosed. The device includes an elongated tube having a proximal end configured to extend outside of the body and a distal end configured to extend proximate the tissue to be invaginated, and a distal member coupled to the distal end of the tube. The distal member is configured to hold or grasp the tissue to be invaginated. The devices may include a protective distal sleeve.

A surgical device for invaginating esophageal tissue of a body, comprising:
- an elongated tube having a proximal end configured to extend outside of the body and a distal end configured to extend proximate the esophageal tissue of the body;
- and
- a distal member coupled to the distal end of the tube, the distal member including a radially expandable portion configured for selective expansion in the radial direction in order to engage esophageal tissue.
A method of invaginating tissue toward an organ having an opening, comprising:
- providing an elongated tube having proximal and distal ends and a distal member coupled to the distal end of the tube, the distal member including a radially expandable portion;
- inserting the elongated tube into a body passage so that a distal end of the tube is proximate the tissue;
- radially expanding the radial expandable portion to engage the tissue;
- and
- displacing the tissue toward the opening of the organ by displacing the distal member.
