Endoscopic suturing devices for transgastric flexible endoscopy procedures are described. In a first aspect, the endoscopic suturing device includes a hollow helical needle carrying an elongated suture thread with a suture anchor on the distal end of the suture thread. The suture anchor has a low-profile insertion position and an expanded anchoring position. A suture lock is provided for attachment at the proximal end of the suture thread. In another aspect, the suture device includes a microcarabiner and suture lock. The suture device may take the form of a conventional suture thread or a zip-tie fastener. In an alternate configuration, the microcarabiner can be combined with a tissue anchor. One or more such tissue anchors can be used to form a running suture, purse string suture or other suture configurations. Methods of applying sutures using the endoscopic suturing devices are described.
