Methods and apparatus for securing and deploying tissue anchors are
described herein. A tissue manipulation assembly is pivotably coupled to
the distal end of a tubular member. A reconfigurable launch tube is also
pivotably coupled to the tissue manipulation assembly, which 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. A deployment assembly is provided for securing
engaged tissue via one or more tissue anchors, the deployment assembly
also being configured to disengage the anchors endoluminally or
laparoscopically by applying thermal energy through at least one suture
cutting element disposed along the deployment assembly.
