Abstract

A surgical suture material is provided with a thread (1) and, in some cases, a needle (2) to allow formation of a knot with the greatest possible security while expending little effort, even in situations where space is limited--for example, during an endoscopic operation. The suture material has at least one inherently stable coil, loop or similar preformed feature in at least one initial preformed section (3,4) of its length. Another section of the thread (1) or an end of the thread can be threaded or guided through this preformed feature for the purpose of forming a loop and/or knot. The preformed section can take the form of a preformed feature with an approximately spiral shape, for example.
