    Abstract: Apparatus & methods for endoscopic suturing are described herein. A distal tip of the endoscopic device engages the tissue and then approximates the engaged tissue to form a tissue fold. A needle body positioned within a flexible catheter is deployed into or through the newly created tissue fold where it is then detached or released from the endoscopic device. The needle body has a length of suture which depends therefrom and can be used to secure the tissue fold. The entire endoscopic device or its tissue engaging assembly can then be rotated relative to the tissue fold while maintaining engagement with the tissue to maneuver the flexible catheter to the opposing side of the penetrated tissue fold. This procedure can be repeated any number of times to create an interrupted, continuous, or running suture to secure the tissue fold.

    Abstract: The attenuation or isolation of environmental parameters on a gastric lumen is described herein. Once tissue plications are formed into a gastric lumen or sleeve within a stomach, the newly formed lumen is subjected to a multitude of fluctuating stresses or pressure from food or fluids passing therethrough, from naturally-occurring contractions, and/or from changes in pH levels from caustic stomach acids and hormones. The tissue interface between these plications can be isolated from such environmental fluctuations, or the fluctuations can be attenuated, by a number of methods. One example is to place a gastric stent or sleeve within the newly formed lumen. Another example is to utilize multiple rows of anchors, clips, or sutures along the interface. Alternatively, bio-adhesives can be dispensed to buttress the tissue interface. In another variation, the tissue can be approximated in different configurations which effectively reduce or isolate the adhered tissue region.
