Abstract:
A fastener for repairing a tear in soft tissue of a patient, the fastener having:a root portion having a proximal end, a distal end, and a distal section having a narrowing cross section toward the distal end; and a helical protrusion atop the root portion along a central section thereof between the proximal end and the distal end, the helical protrusion having a helical pitch along the central section, the helical pitch having a substantially constant value along a distal section extending proximal of the distal end and having a variable value extending proximal of the distal section, wherein the helical pitch decreases from the distal end to the proximal end, and wherein the helical protrusion has a radial depth from an outer edge to the root portion, the radial depth smaller adjacent the distal end than along the variable section.
