Devices and methods for laparoscopically repairing a hernia are described. In some embodiments, a laparoscopic instrument is used to deploy one or more tissue anchor assemblies into the edges of the fascia tissue surrounding or adjacent to the hernia defect. The tissue anchor assemblies are used to cause the fascia tissue to be approximated to facilitate the repair procedure, to improve healing, and to reduce the incidence of recurrence.

An attachment or locking apparatus which can effectively secure an implant, such as a stent or stent graft, to a vessel or hollow organ wall and which allows minimally-invasive techniques, such as laparoscopy, to be used to attach the implant. The locking element is inserted through an anatomic vessel or hollow organ wall and the implant from outside of the vessel or hollow organ. The locking element preferably is composed of a thin retaining element and a clamping element joined flexibly at one end of the retaining element. A fixing element is secured in position on the retaining element to secure or attach the implant in place. A positioning device, including a thin cannula with an attached locking element, may be inserted into the patients body, such that the cannula penetrates both the vascular or hollow organ wall and the implant deployed within the vascular wall. The clamping element, held within the cannula, is then ejected into the vessel or hollow organ. The locking element is pulled tight, and pressure-distribution and/or pressure elements are then slid down the locking element toward the vessel wall or hollow organ.

A surgical scissors instrument having disposed at its distal end two bipolar electrode structures which function to coagulate tissue immediately prior to its being severed by scissor action. The instrument comprises a first scissors blade having a distal end and a second scissors blade having a distal end, wherein at least one of the blades is pivotable in relation to the other blade. A first electrically insulated bipolar electrode structure is disposed longitudinally distally from the distal end of the first scissors blade, and a second electrically insulated bipolar electrode structure is disposed longitudinally distally from the distal end of the second scissors blade. The instrument thereby permits a physician to precisely apply electrical energy only at the distal end of the scissor's blades, and to thereafter immediately cut coagulated tissue situated immediately forward of the blade members.

A catheter includes an introducer and a flow isolator adapted for disposition in a primary conduit to facilitate flow in the primary conduit while inhibiting flow and intersecting secondary conduits. The flow isolator may include a tubular mesh and surrounding balloon structure. Alternatively, a sleeve can be provided with a primary opening and a secondary opening which are sized to inflate the sleeve with the body fluid. Structures for deploying the sleeve between a low-profile state and high-profile state may include expandable fingers, or pneumatic chambers inflatable from an external source. In operation the sleeve can be forced by the body fluid against the intersection with the secondary conduits to achieve isolation. Alternatively, the pneumatic chambers can be inflated to form seals with the primary conduit. A blood filter or snare is contemplated to filter any blood clots which may develop around the flow isolator.

A system for treating gastroesophageal reflux disease (GERD) is disclosed herein. A variety of tools, such as a shape-lockable endoscopic device, can be advanced trans-esophageally and into the stomach or through the stomach wall to access regions of the tissue in and around the gastroesophageal junction. Utilizing expandable tissue anchors, the angle of Hiss can be reconfigured by deploying the anchors within the esophagus and fundus and approximating the two. Alternatively, the esophagus can be lengthened by approximating tissue from within the stomach to follow the lesser curve of the stomach. Alternatively, one or more tissue folds can be formed within or adjacent to the GEJ to form a barrier to refluxing stomach contents.

Apparatus and methods are provided for performing mucosectomy, such as to map out gastrointestinal surgery, including endoluminal gastric reduction. In one variation, tie apparatus comprises a separating element and an integrated resection element. In one variation, the apparatus is configured to simultaneously separate mucosal tissue from underlying muscularis tissue and to resect the separated mucosal tissue. Methods of using the apparatus are provided.
