Knotless micro-suture anchors and anchor arrays for anatomical attachment of soft tissue to bone

A toggle-type suture anchor comprising:

• an elongated body having a proximal end and a distal end defining a longitudinal direction therebetween with at least a first bore and a second bore extending laterally through the elongated body at a spaced interval;
• and,
• a pair of fins projecting both radially outward and proximally from a proximal portion of the elongated body, with at least a portion of each fin extending outwardly beyond a maximum cross-section dimension of the elongated body;
• wherein the proximal end of the elongated body includes a slit between the pair of fins to allow each fin to temporarily flex radially inward when confined.

A toggle-type suture anchor comprising:

• an elongated toggle body having a proximal end and a distal end defining a top surface and a bottom surface, with at least a first hole through the elongated toggle body extending from the top surface to the bottom surface;
• and
• at least one fin projecting from a proximal portion of the elongated toggle body in both a lateral and proximal direction;
• wherein the distal end of the elongated toggle body has an angled lower surface extending upward relative to the bottom surface;
• wherein the at least one fin has an upper surface extending proximally from the top surface and angled downward relative to the top surface;
• and wherein the at least one fin includes a distal portion connected to the elongated toggle body and a proximal portion extending laterally outward from the distal portion of the fin and having a thinned cross section to allow the proximal portion to temporarily flex laterally inward when confined.
