17. A method for repairing a fractured or weakened articular head of a bone, the method comprising:
-
removing the fractured or weakened head from the bone; placing an expandable member removably attached to a distal end of a delivery catheter at least partially into an intramedullary cavity of the bone; attaching an articular member having a bearing surface to the expandable member; infusing a light sensitive liquid into the expandable member through an inner lumen of the delivery catheter to adjust a position, an angulation, an alignment or some combination thereof of the articular member; activating a light conducting fiber to cure the light sensitive liquid inside the expandable member; and separating the expandable member and the articular member from the delivery catheter. - View Dependent Claims (18, 19, 20)
