Internal bone fixation system with integrated mixer

摘要

Systems and methods for repairing a weakened or fractured bone are disclosed herein. A system for repairing a fractured bone includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the delivery catheter has an inner void for passage of bone cement components and an inner lumen for passage of a mixing element; an internal bone fixation device releasably engaging the distal end of the delivery catheter, wherein the internal bone fixation device moves from a first compact state to a second expanded state when the bone cement components are delivered to the internal bone fixation device and mixed within the internal bone fixation device; and a spinning mechanism engaged to a rotatable shaft, wherein the spinning mechanism is inserted into the internal bone fixation device.
