Suture anchor with microthreads and suture anchor driver with needle attachment

A suture anchor, comprising:

• an elongate anchor body having a proximal end, a distal end and a length therebetween;
• at least one major thread covering the length of the anchor body, wherein the at least one major thread has a major diameter between 2 mm and 10 mm and a thread pitch between 0.1 mm and 5 mm;
• and
• at least two minor threads covering the length of the anchor body,
• wherein the at least two minor threads occupy a space between the at least one major thread, wherein the at least two minor threads have major diameters between 1 mm and 9 mm and thread pitches between 0.1 mm and 5 mm, and wherein the major diameters of the at least two minor threads are smaller than the major diameters of the at least one major thread;
• wherein the at least one major thread has a first angular profile comprising a proximal major thread face and a distal major thread face, wherein the proximal major thread face extends substantially planar at a first angle from a root of the anchor with a longitudinal axis of the elongated body, wherein the distal major thread face extends substantially planar from a root of the anchor and makes a second angle less than 90 degree with the longitudinal axis, and wherein the first angle is closer to perpendicular with the longitudinal axis than the second angle;
• wherein each of the at least two minor threads have a second angular profile comprising a proximal minor thread face and a distal minor thread face, wherein the proximal minor thread faces makes a non-perpendicular angle less than 90 degrees with the longitudinal axis and the distal minor thread faces makes a non-perpendicular angle less than 90 degrees with the longitudinal axis;
• and
• wherein the first and second angular profiles are different along the length, and wherein the at least two minor threads extend to their major diameter in the second angular profile distal from where the at least one major thread extends to its major diameter in the first angular profile.
