1. An assembly for securing soft tissue, the assembly comprising:
- an inserter having a proximal end and distal end, the inserter including a handle near the proximal end, the inserter including a shaft between the handle and the distal end;
an anchor body near the distal end of the inserter, the anchor body having a proximal edge received against a distal edge of the shaft;
a suture including a portion establishing a suture loop near the distal end, the suture loop being distal of the anchor body, the suture including a portion within the shaft, the suture having two ends that protrude outside of the inserter near the proximal end; and
a rotatable member near the handle and wherein rotational movement of at least one of the handle or the rotatable member causes a change in position of the anchor body relative to the suture loop.

Abstract
An illustrative example inserter assembly for securing soft tissue in a position adjacent bone includes an inserter having a proximal end and distal end. The inserter includes a handle near the proximal end and a shaft between the handle and the distal end. An anchor body is situated near the distal end of the inserter. A suture includes a portion establishing a suture loop near the distal end where the suture loop is distal of the anchor body. The suture includes a portion within the shaft. The suture has two ends that protrude from the inserter near the proximal end.

17. A tissue securing assembly, comprising:
-
an inserter including a distal end and a proximal end, the inserter including a handle near the proximal end, the inserter having a longitudinal axis between the distal end and the proximal end, the inserter including a shaft along the longitudinal axis; an anchor body near the distal end, the anchor body being configured to be received in a hole in bone for trapping at least a portion of soft tissue in bone, the anchor body having a proximal edge that is received against a distal edge of the shaft; a tissue gathering portion near the distal end, the tissue gathering portion being distal of the anchor body, the tissue gathering portion being configured to at least temporarily gather a portion of soft tissue near the distal end of the inserter for moving the portion of soft tissue with the distal end of the inserter into a hole in bone; a second portion coupled to the tissue gathering portion, the second portion extending along the longitudinal axis from the tissue gathering portion to near the proximal end, the second portion being at least partially within the inserter and at least partially protruding outside of the inserter, the second portion being at least partially within the shaft, the second portion being moveable relative to the handle to change a position of the tissue gathering portion relative to the anchor body; and a rotatable member near the handle and wherein rotational movement of at least one of the handle or the rotatable member causes a change in position of the anchor body relative to the tissue gathering portion. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
