The frame of the implant provides radial expansion properties to secure the cover within a body vessel. The cover and/or the frame can occlude flow of a fluid through the body vessel. ## Claims ### Claim 1 A method of assembling an implant delivery system, comprising: providing an implant, in a relaxed state, to a catheter having a kerf (1) extending from and through an outer surface of the catheter into a lumen of the catheter, and (2) extending in a first helical direction and defining opposing sides along a helical coil; engaging a first end portion of the implant with a proximal portion of the catheter; and engaging a second end portion of the implant with a distal portion of the catheter, such that the implant is held in a torsional state by the catheter, and such that the implant applies a torque to the catheter to cause opposing sides of adjacent windings of the coil between the proximal portion and the distal portion to be pulled toward each other. ### Claim 2 (depends on 1) The method of claim 1, wherein the kerf has a non-linear profile following a helical path. ### Claim 3 (depends on 2) The method of claim 2, wherein, the non-linear profile comprises a triangular profile. ### Claim 4 (depends on 2) The method of claim 2, wherein, the non-linear profile comprises a sawtooth profile. ### Claim 5 (depends on 2) The method of claim 2, wherein, the non-linear profile comprises an undulating profile. ### Claim 6 (depends on 1) The method of claim 1, wherein the implant further comprises a helical member extending in a second helical direction, opposite the first helical direction. ### Claim 7 (depends on 1) The method of claim 1, wherein, while the implant is in the relaxed state, the proximal portion is configured to disengage from the first end portion and/or the distal portion is configured to disengage from the second end portion. ### Claim 8 (depends on 1) The method of claim 1, wherein the kerf is defined between adjacent windings of the helical coil, and while the implant is in the torsional state, the adjacent windings of the helical coil contact each other. ### Claim 9 (depends on 1) The method of claim 1, wherein the kerf is defined between adjacent windings of the helical coil, and while the implant is in the relaxed state, the adjacent windings of the coil are spaced apart from each other by a gap. ### Claim 10 (depends on 1) The method of claim 1, wherein the torque causes opposing sides of adjacent windings of the coil between the proximal portion and the distal portion to be pulled toward each other. ### Claim 11 (depends on 1) The method of claim 1, wherein the kerf extends between adjacent windings of the coil. ### Claim 12 A method of assembling an implant delivery system, the method comprising: providing a catheter comprising a proximal portion, a distal portion, and a helical coil extending in a first helical direction and connecting the proximal portion to the distal portion, the coil being defined by a kerf between adjacent windings of the coil; engaging a first end portion of an implant with the catheter proximal portion, the implant being biased to a relaxed state; moving the implant away from the relaxed state to a collapsed state and engaging a second end portion of the implant with the catheter distal portion such that the implant applies a torque to the catheter to reduce a width or pitch of the kerf between adjacent windings of the catheter coil. ### Claim 13 (depends on 12) The method of claim 12, wherein the kerf has a non-linear profile following a helical path. ### Claim 14 (depends on 12) The method of claim 12, wherein the implant further comprises a helical member extending in a second helical direction, opposite the first helical direction. ### Claim 15 (depends on 12) The method of claim 12, wherein, while the implant is in the relaxed state, the adjacent windings of the coil are spaced apart from each other by a gap. ### Claim 16 (depends on 12) The method of claim 12, wherein, while the implant is in the relaxed state, the proximal portion is configured to disengage from the first end portion and/or the distal portion is configured to disengage from the second end portion. ### Claim 17 A method of assembling an implant delivery system, the method comprising: providing a catheter comprising a proximal portion, a distal portion, and a kerf that defines windings of the catheter that connect the proximal portion to the distal portion and are movable relative to each other; and compressing an implant onto the catheter to couple (i) a first end portion of the implant to the catheter proximal portion and (ii) a second end portion of the implant to the catheter distal portion such that the implant is engaged on the catheter in a collapsed state to apply a torque to the catheter, thereby reducing a width or pitch of a gap between adjacent windings. ### Claim 18 (depends on 17) The method of claim 17, wherein the catheter comprises a coil wherealong the kerf extends between adjacent windings of the coil. ### Claim 19 (depends on 17) The method of claim 17, wherein the kerf has a non-linear profile following a helical path.
