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.

Abstract: Described herein suture passer apparatus (devices and systems) that may be used to suture tissue within a narrow, confined space. In particular, described herein are suture passers having an elongate body and a bent lower jaw member that houses a tissue penetrator that is adapted to extend laterally through the bend region, and then be laterally deflected from the lower jaw member to a second jaw (e.g. bendable or pivoting) upper member.
