Tissue manipulation and securement system
First Claim
1. A method of securing tissue, comprising:
- advancing an elongate flexible member to a surgical site in a patient, with the elongate flexible member having a first jaw pivotally attached to a distal end of the elongate flexible member at a first pivot coupling, and a second jaw pivotally attached to the first jaw at a second pivot coupling, and a launch tube extending through a lumen of the elongate flexible member and connecting only to the second jaw at a launch tube pivot coupling distal of the first and second pivot couplings, with the second pivot coupling between the first pivot coupling and the launch tube pivot coupling, and, the launch tube having a substantially tubular shape defining an internal lumen;
moving the first jaw relative to the elongate member distal end by translating the launch tube relative to the elongate flexible member;
moving the second jaw toward the first jaw by translating the launch tube relative to the elongate flexible member.

Abstract
Tissue manipulation and securement systems are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member and has a lower jaw member and an upper jaw member pivotably coupled to the lower jaw member. A reconfigurable launch tube is also pivotably coupled to the upper jaw member and is used to urge the jaw members from a low-profile configuration to an open configuration for receiving tissue. The tissue manipulation assembly may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly.

11. A method of securing tissue within a hollow body organ, comprising:
-
endoluminally advancing a tubular body into a hollow body organ, with the tubular body including a set of jaws comprising a first jaw and a second jaw, each having a front end and a back end, with the back end of the first jaw pivotally attached to a front end of the tubular body at a first pivot coupling, and with the back end of the second jaw pivotally attached to the first jaw member at a second pivot coupling between the front and back ends of the first jaw; opening the set of jaws by pulling back a launch tube attached only to the second jaw; engaging tissue of the hollow body organ between the first jaw and the second jaw; and closing the set of jaws onto the tissue by pushing forward on the launch tube. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
