Patent ID: 7604636

Claim:
A method of forming a non-linear tunnel through a bone structure, comprising: positioning at least a portion of a flexible single shaft cutting tool through a flexible guide mechanism; positioning the flexible single shaft cutting tool adjacent to the bone structure at a first bone location; guiding the flexible single shaft cutting tool with the flexible guide mechanism from the first bone location to a second bone location; cutting a non-linear path with the flexible single shaft cutting tool through the bone structure from the first bone location to the second bone location so as to cause the flexible single shaft cutting tool to enter the bone structure at the first bone location and exit the bone structure at the second bone location; associating a suture engaging hook with the flexible single shaft cutting tool; engaging a suture with the suture engaging hook at the second bone location; and pulling the suture through the non-linear path from the second bone location to the first bone location to secure the suture to a selected tissue near to the first and second bone location after the non-linear path has been formed.
