A suture securing device includes an inner member defining a suture receiving passage extending between a distal end surface of the inner member and a second surface of the inner member. An outer member defines an opening for receiving the inner member such that suture extending from the second surface is secured between the inner member and the outer member. The second surface is a proximal end surface of the inner member, and a slot extends between an outer surface of the inner member and the passage. Suture is threaded through the inner member in a proximal direction, and the outer member is advanced over the inner member to cause the suture to double back in a distal direction. A suture securing cartridge includes a sleeve having an axial bore with the suture securing device disposed in the bore.
