TISSUE MANIPULATION AND SECUREMENT SYSTEM

摘要

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.

1. A surgical method comprising:
moving an endoscopic body trans-orally to a surgical site within a patient; engaging tissue at the surgical site with a tissue engagement member; grasping the engaged tissue with jaws; passing a needle through the engaged tissue while the tissue remains engaged by the tissue engagement member and grasped by the jaws; deploying a tissue anchor from the needle; withdrawing the needle from the engaged tissue; releasing the jaws from the tissue; and releasing the tissue engagement member from engagement with the tissue.
