a length of suture having a first end attached to said first fastener element and a second end attached to said second fastener element; and
a surgical suture holding device including
a first fastener element holding device including a first needle, where said first needle has a first tip, where said first needle is sized to accept said first lumen, and
a second fastener element holding device adapted to accept said second fastener element,
where, with said first needle placed through said first lumen, and when said distal end of said first fastener element is inserted into the distal end of said second lumen of said second fastener element, said first plurality of locking elements interact with said second plurality of locking elements to inhibit movement of said first fastener element from said second fastener element.
12. The apparatus of claim 11 , where said first fastener element holding device is configured to locate said first fastener element at a specific location in said first fastener element holding device.
13. The apparatus of claim 11 , where said second fastener element holding device is configured to locate said second fastener element at a specific location in said second fastener element holding device.
