a second coupling component coupled to the second end portion of the implant, the second coupling component defining a second slot, the second slot having an opening on a lateral edge of the second coupling component that extends into the second coupling component;

an insertion tool having a needle member defining a slot;

a first delivery member, the first delivery member being a first suture, the first delivery member having a first elongate portion and a second elongate portion, the first elongate portion including a first loop and being configured to be removably coupled to the first slot of the first coupling component via the opening of the first slot, the first loop being defined by the first suture and a coupling member, the second elongate portion including a second loop, the coupling member being fixedly disposed between the first loop and the second loop, the second loop being defined by the first suture and the coupling member, the coupling member being disposed between the first elongate portion of the first delivery member and the second elongate portion of the first delivery member, the first loop being coupled to the second loop via the coupling member, the first loop being disposed distally from the second loop, the first loop being longer than the second loop, the second loop configured to be removably coupled to the slot of the needle member; and

a second delivery member, the second delivery member being a second suture separate from the first suture, the second delivery member having a first elongate portion and a second elongate portion, the first elongate portion of the second delivery member including a first loop defined at least partially by the second suture, the first loop of the first elongate portion of the second delivery device being configured to be removably coupled to the second slot of the second coupling component via the opening of the second slot, the second elongate portion of the second delivery member including a second loop defined at least partially by the second suture, the second loop of the second elongate portion of the second delivery member configured to be removably coupled to the slot of the needle member.

8. The kit of claim 7, wherein the first and second slots are L-shaped slots.

9. The kit of claim 7, wherein the first coupling component includes two pieces that are coupled together, the first end portion of the implant being disposed between the two pieces.

10. The kit of claim 7, wherein each of the first and second slots has a first portion extending along a first axis and a second portion extending along a second axis, the first axis being non-parallel to the second axis, the second portion having an end portion wider than a mid-portion of the second portion.

11. The kit of claim 7, wherein the first loop of the first elongate portion of the first delivery member is a first complete loop, and the second loop of the second elongate portion of the first delivery member includes a second complete loop.

12. A method of inserting an implant within a body of a patient, comprising:

inserting a delivery member into the body of the patient such that a first portion of the delivery member is disposed within the body of the patient and a second portion of the delivery member extends from the body of the patient, the delivery member being a suture such that the first portion of the delivery member defines a first loop and the second portion of the delivery member defines a second loop, the second loop being longer than the first loop;

19. The method of claim 12, wherein the first loop is a first complete loop, and the second loop is a second complete loop, wherein the cutting includes cutting the first complete loop and the moving includes moving the second complete loop in a direction away from the implant such that a portion of the first complete loop moves towards the implant and then away from the implant while the second complete loop is moved in the direction away from the implant.

20. The method of claim 12, the delivery member being a first delivery member, the end portion of the implant being a first end portion, the method further comprising:

inserting a second delivery member into the body of the patient such that a first portion of the second delivery member is disposed within the body of the patient and a second portion of the second delivery member extends from the body of the patient;

coupling the second portion of the second delivery member to a second end portion of the implant after the inserting of the second delivery member;

disposing the second end portion of the implant within the body of the patient; and

decoupling the second portion of the second delivery member from the second end portion of the implant while the second end portion of the implant is disposed within the body of the patient.
