An incontinence treatment device (20) includes a non-porous sling (22) located between two anchors (40, 42). A first line (50) is attached between a first end (24, 92) of the sling (22) and the first anchor (40), and a second line (52) is attached to a second end (26, 94) of the sling (22) and inserted through a channel (90) of the second anchor (42). The second anchor (42) is provided with a restrictor segment (96) provided in the channel (90). The second line (52) has an adjustment device (70) attached to the second line (52) and the restrictor segment (96) is configured to resist movement of the adjustment device through the channel (90). The adjustment device is movable through the channel (90) from a first position that locates the adjustment device between the second anchor (42) and the sling (22) to a second position that locates the second anchor (42) between the adjustment device and the sling (22) to thereby reduce an effective length of the sling (22) between the first and second anchors (40, 42).
