The OTSC system set has an applicator cap with a mounted OTSC clip, thread, thread retriever and a hand wheel for clip release. The OTSC clip is made of super elastic nitinol which is used for flexible endoscopy, compression and approximation of tissues in the human digestive tract. The OTSC clip is supplied by means of an applicator cap placed to the tip of gastro scopes or colonoscopes. The clip is let out by tightening the thread with the hand wheel. The clip is uniquely designed so that it can close itself and firmly secures the tissue to be compressed for hemorrhage or closure of a GI organ wall wound. OTSC offers continuous force at the implantation site fixing the therapeutic effect because of its smart material properties. OTSC is composed of a biocompatible material and can stay in the body as an implant for a long term.
