US Patent 7285124 Single-tailed suturing method

A suture loop is formed in a hollow braided suture by feeding one end of a length of suture through a part in the braid of the suture and into the inner lumen formed by the hollow braid. The braided configuration of the suture allows it to be expanded in diameter by pushing and reduced in diameter by pulling. Said end of suture is passed continuously through said inner lumen forming a loop of suture with a single tail. The loop may be tightened by pulling on said first end of the suture while pushing on said outer hollow braid. The loop may be locked by extending or pulling on said outer hollow braid to reduce its diameter and lock it down around said first end of the suture.
