Systems and methods for internal bone fixation

Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. According to aspects illustrated herein, there is provided a device (700) for repairing a fractured bone that includes a delivery (710) having an elongated shaft (701) with a proximal end, a distal end, and a longitudinal axis therebetween, the delivery catheter (710) having an inner void (713) for passing at least one reinforcing material, and an inner lumen (711) for accepting a light pipe (652), wherein a distal end (723) of the inner lumen (711) terminates in an optical lens (754); a conformable member (703) releasably engaging the distal end of the delivery catheter (710), the conformable member (703) moving from a deflated state to an inflated state when the at least one reinforcing material is delivered to the conformable member (703); and an adapter releasably engaging the proximal end of the delivery catheter (710) for receiving the light pipe (652) and the at least one reinforcing material.
