Method for securing tissue
An apparatus and method is disclosed for securing tissue to a bone comprising a novel screw anchor for insertion into a bone by a novel rotational driver. The screw anchor and rotation driver enables the screw to be completely embedded into the bone while permitting a suture to be threaded through a transverse aperture in the screw. The rotation driver facilitates insertion and engagement of a capture with one of a series of protuberance formed along a length of a suture. In addition, the method is disclosed of forming the series of protuberance.
1. A method of moving a capture along a suture with a driver, the suture having a series of protuberances spaced apart along a length thereof, the capture having a central locking aperture for moving over the series of protuberances in a first direction and for resisting moving over the series of protuberances in a second direction, comprising the steps of
threading the suture through a central aperture in the capture and through a central orifice in the driver to extend outside and adjacent to the driver;
positioning the central aperture in the capture in alignment with the central orifice in the driver; and
moving the driver relative to the suture to move the capture along the suture to lockingly engage the capture with one of the series of protuberances.

threading the suture through the central locking aperture in the capture and a central orifice in the driver to extend outside and adjacent to the driver;
positioning the central locking aperture in the capture in alignment with the central orifice in the driver; and
moving the driver relative to the suture extending outside of the driver to move the capture along the suture in the first direction to lockingly engage the capture with one of the series of protuberances.
