Endoscopic plication of massively bleeding peptic ulcer by using the Eagle Claw VII device: a feasibility study in a porcine model.

Background And Objective: We examined the efficacy of endoscopic plication when using Eagle Claw VII in a porcine bleeding ulcer model. ANIMAL MODEL PREPARATION: The right gastroepiploic artery (diameter 1.5-2 mm) was isolated and was tunneled to small gastrotomies at either the lesser or greater curvature of the stomach.

Eagle Claw II: A novel endosuture device that uses a curved needle for major arterial bleeding: a bench study.

Background: Control of bleeding from major arteries in the upper-GI tract remains difficult with currently available endoscopic devices. We designed an endosuture device that uses a curved needle and extracorporeal knotting, and assessed the device in stopping arterial bleeding in a bench model.

Methods: Harvested porcine splenic arteries (2-mm diameter) were tunneled submucosally in pig stomach with the open end protruding into an artificially created mucosal defect.

Endoscopic suturing without extracorporeal knots: a laboratory study.

Background: To eliminate cumbersome extracorporeal knotting, we designed a new endoscopic suturing device, the Eagle Claw V. The efficacy of the new device was tested on the Erlangen model and was compared with the initial extracorporeal knotting version (Eagle Claw II).

Methods: Segments of porcine splenic arteries were placed on the mucosal surface of the anterior wall of a pig stomach.
