Abstract

Devices for easily and quickly tying complex suture knots are disclosed. The knot tying accessories described herein provide a means for introducing a complex knot pattern into a bight of suture using a device body and a guide thread. The device body includes system for maintaining the guide thread and suture in a convoluted pathway, either with the use of channels, protrusions, or a combination of both within its interior, on its exterior, or both. The guide thread may include a coupler at one end for holding a suture end while the guide thread leads the suture through the convoluted path defined within the guide body. Pull tabs may also be included to aid with exchanging the guide thread for the suture ends.
