Endoscopic clip systems for hemostasis and defect closure in gastrointestinal endoscopy

Table 1 Features of through-the-scope clips

Feature	Importance
Open width	Determines the width of tissue grasp; distance between the distal teeth when the clip is opened to the maximum
Stem/tail length	Affects reach, especially in deeper lesions; also important to consider on narrow areas
Rotatability	Allows precise positioning
Overshoot	Rotation exceeding 30 degrees after stopping
Open-close mechanism	Allows repositioning of clips prior to deployment
Tensile strength	Grasp of the clip to the apposed mucosa
