Claim:
1. A device for bone fixation comprising: a delivery catheter comprising an outer tube and an inner tube, the inner tube disposed within the outer tube and the inner tube extending beyond the outer tube; an expandable member having a proximal region and an open distal region, the expandable member being releasably attached about a distal end of the delivery catheter at the proximal region of the expandable member; and a distal cap comprising an outer surface, an inner surface and a body extending from the inner surface, wherein an outer diameter of the body is smaller than a diameter of the inner surface to provide a recessed attachment section, the open distal region of the expandable member being attached to an outside of the body at the recessed attachment section, and wherein the distal cap terminates and seals off the open distal region of the expandable member to prevent the flow of a light-sensitive liquid from inside to outside of the expandable member and the ingress of bodily fluids inside the expandable member; and an inner compartment defined by an inside of the body of the distal cap in the open distal region of the expandable member, wherein the inner compartment is sized so when the inner tube is inserted into the inner compartment, the inner tube is freely moveable within the inner compartment in a radial direction.
