An apparatus includes an elongate member, an actuator, and a thread member. A portion of the elongate member defines a central axis. The elongate member defines a slot which extends along an axis parallel to the central axis. The actuator is coupled to the elongate member and is accessible through the slot. The actuator is moveable from a first position to a second position different than the first position. The thread member is coupled to the actuator and has a receiving portion. The thread member is moveable from a first position to a second position different than the first position when the actuator is moved from its first position to its second position. A portion of the thread member is disposed within a lumen defined by the elongate member when the thread member is in its first position. At least a portion of the thread member extends from a distal opening defined by the elongate member when the thread member is in its second position.
