101:) were limited by the applicator system of the clip. However, by 1988, an easy to use applicator delivery system was developed, and a functional reloadable endoclip system was described. This consisted of a stainless steel clip (of size approximately 6 mm long and 1.2 mm wide at the prongs) with a metal deployment device (that could be used to insert the clip into the endoscopic camera, and deployed outside the camera) enclosed in a plastic sheath. These clips were initially reloadable. 205: 19: 90: 253:
Endoclips have been seen to dislodge between 1 and 3 weeks from deployment, although lengthy clip retention intervals of as high as 26 months have been reported. Endoclips are believed to be safe and no major complications (such as perforation or impaction) have been reported with them, although
