A secure locking knot for microsuturing

Perfect balance between maximal suture strength and minimal foreign-body reactivity guarantees success, using microsurgical techniques. The proposed initial locking knot allows optimal edge approximation. It has strength, it is simple to master, and is not too bulky. The knot is kept in its first position, without danger of slipping, before securing it with an additional knot of two loops. No additional knots are necessary, because the completed knot may fail by breaking, but never by slippage.
