1. An apparatus comprising:
a pusher having a distal end;
a needle having a distal portion, the needle slidably disposed within the pusher with the distal portion of the needle extending from the distal end of the pusher; and
a suture having a first section and a second section, each of the first section and the second section having a first portion and a second portion, the second portion of each section including a coil that has a proximal end and a distal end and being formed of multiple turns about an exterior of the needle, a first end of the second portion of the first section being at the distal end of the coil of the first section;
a first end of the second portion of the second section coupled to the first end of the second portion of the first section;
the first section forming a first loop forming segment having a first end at the proximal end of the first coil, a second end at the distal end of the first coil, and being routed proximally external to the second coil and distally internal to the second coil;
the second section forming a second loop forming segment having a first end at the distal end of the second coil, a second end at the proximal end of the first coil, and being routed distally external to the first coil and proximally internal to the first coil;
the second section forming a first loop by routing the first portion of the second section proximally along the exterior of the coil of the second section and distally through the proximal end of the coil of the second section, internal to the coil of the second section, and out a portion of the coil of the second section between the distal end and the proximal end of the coil of the second section;
the first section forming a second loop by routing the first portion of the first section distally along the exterior of the coil of the second section and proximally through the distal end of the coil of the first section, internal to the coil of the first section, and out a portion of the coil of the first section between the distal end and the proximal end of the coil of the first section;
the first portion of the first section being crossed with the first portion of the second section and routed through the first loop; and
the first portion of the second section being crossed with the first portion of the first section and routed through the second loop.
