Sutures that need no knots

The new knotless tissue control devices will allow surgeons to stitch and secure tissues without needing to tie knots in the sutures.
The devices will be lined with barbs, which will be spaced 1mm apart and form a spiral along length of the string. The barbs will help maintain the tension in the suture while also providing anchor points that will eliminate the need to tie knots, thus allowing surgeons to close wounds more rapidly and reduce the amount of time patients are under anesthesia.
