Abstract
An endoscopic clip device for closure of a mucosal defect or transmural perforation in a gastrointestinal wall may include a sleeve and a clip disposed at least partially within and coupled to the sleeve. The clip may be configured for reversibly moving between an open configuration for positioning relative to the wall and a closed configuration for closing the defect or perforation. The clip may include a first clip arm configured for engaging the mucosal and submucosal layers of the wall and including a first needle extending to a distal end of the first clip arm and configured for advancing through the mucosal layer and into at least the submucosal layer, and a second clip arm disposed opposite the first clip arm and configured for engaging the mucosal layer. The device may be configured for advancing through an operative channel of an endoscope or overtube having a tortuous shape.
