Patent ID: 7842040

Claim:
A system for repairing a fractured bone comprising: 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; an internal bone fixation device releasably engaging the distal end of the delivery catheter and adapted to move from a first compact state to a second expanded state; and a mixing element sized to pass through the inner lumen, the mixing element comprising a spinning mechanism releasably engaged to a distal end of a rotatable shaft, wherein the spinning mechanism is inserted into the internal bone fixation device and rotation of the rotatable shaft about a central axis rotates the spinning mechanism about the central axis so that the spinning mechanism contacts the bone cement components to mix the bone cement components together, and wherein the mixing element is sufficiently designed to disengage the spinning mechanism from the rotatable shaft.
