a pre-tied knot body formed from the suture material at a region near the first end of the suture, the pre-tied knot body having one or more loops of the suture material, wherein each loop has at least one crossing point; and a leader snare formed of a length of linear and flexible material, wherein the pre-tied knot body is tied around the leader snare so that the leader snare passes through the one or more loops of the knot body, wherein a bight region of the leader snare extends from a first end of the knot body and a pull tail extends from a second end of the knot body, wherein the material forming the leader snare has a larger diameter than the suture material of the elongated flexible length of suture material, wherein the knot body and leader snare are sufficiently flexible and narrow of profile to be pulled through a tissue behind a tissue penetrator. ### Claim 2 (depends on 1) The suture of claim 1, wherein the pre-tied knot body comprises three or more loops of suture material. ### Claim 3 (depends on 1) The suture of claim 1, wherein the leader snare is formed of a second suture material. ### Claim 4 (depends on 1) The suture of claim 1, wherein the bight region of the leader snare extends towards the second end of the elongate flexible length of suture material, and the pull tail of the leader snare extends towards the first end of the elongate flexible length of suture material. ### Claim 5 (depends on 1) The suture of claim 1, wherein the knot body is configured to slide along a length of the suture. ### Claim 6 (depends on 1) The suture of claim 1, wherein the pre-tied knot body comprises at least two loops of the suture material. ### Claim 7 (depends on 1) The suture of claim 1, wherein each loop comprises at least two crossing points. ### Claim 8 (depends on 1) The suture of claim 1, wherein the pull tail comprises a first end or a second end of the length of linear flexible material. ### Claim 9 (depends on 1) The suture of claim 1, wherein the pull tail comprises a first and a second end of the length of linear flexible material. ### Claim 10 (depends on 1) The suture of claim 1, wherein the pull tail comprises a first and a second end of the length of linear flexible material secured together as a single end region. ### Claim 11 (depends on 1) The suture of claim 1, wherein one or both of the first and second ends of the elongate flexible length of suture material pass through the bight region of the leader snare. ### Claim 12 (depends on 1) The suture of claim 1, wherein a length of the suture material extends from a suture anchor that is configured to be secured to a bone. ### Claim 13 (depends on 1) The suture of claim 1, wherein the pre-tied knot body is configured as a suture trap that allows one-way passing of the elongate flexible length of suture material through the pre-tied knot body. ### Claim 14 (depends on 13) The suture of claim 13, wherein the suture trap is coupled to the leader snare. ### Claim 15 (depends on 13) The suture of claim 13, wherein the suture trap is formed into the suture material, secured over the suture material, or secured in the suture material. ### Claim 16 (depends on 1) The suture of claim 1, wherein the leader snare is formed of a nitinol wire or string material. ### Claim 17 (depends on 1) The suture of claim 1, wherein the length of linear and flexible material is distinct from the suture material. ### Claim 18 (depends on 1) The suture of claim 1, wherein the leader snare is formed of a piece of suture material. ### Claim 19 (depends on 1) The suture of claim 1, wherein the pre-tied knot body is formed of a polymeric, metal, alloy or ceramic material.
