Abstract
Abstract The suture lock or suture lock rivet for locking suture thread includes a lock head defining a cut-out, a first locking surface and a stem connected via a breakaway section. The lock also includes a lock base defining a second complementary locking surface. The locking surfaces trap the suture in the cut-out. The stem breaks away. A suture lock applicator is utilized to deliver and apply the suture lock to the surgical site. The system includes the lock loaded within the suture lock applicator. The applicator, or rivet gun, is designed to grip the stem body and coact with the lock base to cause the lock base to slide over the stem towards the lock head or rivet head, and subsequently, with the application of additional longitudinally directed force, to remove the stem from the lock head or first body part at the breakaway section.
