An adjustable single-incision sling system, includes a tissue support portion, a first tissue anchor, and a second tissue anchor. The first tissue anchor connects to the tissue support portion via a first arm, which spaces the first tissue anchor from the tissue support portion a fixed first distance. The second tissue anchor connects to the tissue support portion via a second arm, which has a free end passing through the second tissue anchor spacing the second tissue anchor from the tissue support portion a variable second distance, such that movement of the free end with respect to the second tissue anchor decreases the second distance.
