A system for manipulating a rotational device using a flexible guide rod with an external rod feature along its length to engage a rotational device with a complementary interior channel feature along its length. A driver having a handle and coupling element is coupled to the rotational device while the flexible guide rod extends from the handle, through the coupling element, and into the interior channel of the rotational device in order to rotate from within along the length of the device.
A tool for manipulating flexible and non-flexible fastening devices. The tool assembly has a flexible rod for insertion into the distal end of the fastening device. A handle assembly interacts with proximal end of the flexible rod and the proximal end of the fastening device to control of the fastening device by initiating rotation at the distal end of the fastening device.
