Suture lock, lock applicator and method therefor

A suture lock rivet for locking at least one suture thread, said suture lock rivet comprising:

• a rivet having a rivet head on a rivet stem, said stem having a first body part and a second body part separated by a breakaway section;
• said first body part being adjacent said rivet head and defining a cut-out adapted to capture said at least one suture thread therein, and said first body part defining a first locking surface thereon;
• a lock base defining a longitudinal passage adapted to mate with said rivet stem, said base defining a second locking surface complementary to said first locking surface;
• and
• said base adapted to lock onto said rivet stem via said first and second locking surfaces such that said at least one suture thread is trapped in said cut-out and said second body part is adapted to break away from said first body part.

A suture lock rivet and delivery gun system for locking at least one suture thread, the system comprising:

• a rivet having a rivet head on a rivet stem, said stem having a first body part and an elongated second body part separated by a breakaway section;
• said first body part being adjacent said rivet head and defining a cut-out adapted to capture said at least one suture thread therein, and said first body part defining a first locking surface thereon;
• a lock base defining a longitudinal passage adapted to mate with said rivet stem, said base defining a second locking surface complementary to said first locking surface;
• said base adapted to lock onto said rivet stem via said first and second locking surfaces such that said at least one suture thread is trapped in said cut-out and said second body part is adapted to break away from said first body part;
• and
• a rivet gun gripping a proximal portion of said elongated second body part of said stem and coacting with said lock base to force said base over said second body part towards said rivet head thereby locking said head onto said base prior to said break away.

A method of locking at least one suture thread a surgical site comprising:

• providing a lock head and a lock base;
• capturing said at least one suture thread with said head;
• cinching said at least one suture thread;
• fastening said lock base onto said head such that said at least one suture thread is trapped therebetween.
