摘要：
An endoscopic closure device comprises: a coupling member a helical needle mounted to the coupling member and carrying a suture and a plurality of grasping needles, each of said plurality of grasping needles moveable between a storage position and a deployed position. The plurality of grasping needles is configured to be (a) advanced in the storage position into a luminal defect, (b) moved into the deployed position, and (c) then refracted from the luminal defect, thus pulling and drawing tissue surrounding the luminal defect together. Then, upon rotation of the coupling member and the helical needle, the helical needle is driven into and pierces the tissue, carrying the suture through the tissue.
