Patent ID: 8177847

Claim:
A method for repairing an imperfection on a disc associated with a spinal column, the method comprising: puncturing a first portion of the disc on a first side of the imperfection with a first penetrating member carrying a first end portion of a prosthesis; inserting the first end portion of the prosthesis into the first portion of the disc including: moving a trigger a first trigger distance; moving a first cam a first cam distance in response to moving the trigger the first trigger distance; moving a first follower a first follower distance in response to moving the first cam the first cam distance; and ejecting the first end portion of the prosthesis from the first penetrating member in response to moving the first follower the first follower distance; puncturing a second portion of the disc spaced from the first portion of the disc on a second side of the imperfection with a second penetrating member carrying a second end portion of the prosthesis; inserting the second end portion of the prosthesis into the second portion of the disc including: moving the trigger a second trigger distance; moving a second cam a second cam distance in response to moving the trigger the second trigger distance; moving a second follower a second follower distance in response to moving the second cam the second cam distance; and ejecting the second end portion of the prosthesis from the second penetrating member in response to moving the second follower the second follower distance; and securing the first side of the imperfection to the second side of the imperfection in response to inserting the second end portion of the prosthesis into the second portion of the disc.
