Suture anchor implantation instrumentation system

A system for implanting an anchor into bone, the system comprising:

• a curved cannulated guide for accessing an internal anatomical site, having a proximal end and a distal end, the curved cannulated guide being rigid;
• a flexible obturator insertable through the curved guide from the proximal end to the distal end, the flexible obturator having a shaft made of a nitinol;
• a flexible drill insertable through the curved guide from the proximal end to the distal end, the flexible drill having a shaft including a flexible portion, the flexible portion comprising a plurality of discrete interlocking portions;
• and
• a flexible inserter for inserting a suture anchor into a bore at the anatomical site formed by the flexible drill,
• wherein the flexible obturator, flexible drill and flexible inserter are flexible so as to pass through a curve positioned between the proximal end distal end of the rigid curved cannulated guide.
