Abstract
An embodiment of a bone stabilization and distraction system of the present disclosure includes a light-sensitive liquid; a light source for providing light energy; a light-conducting fiber for delivering the light energy from the light source to cure the light-sensitive liquid; a delivery catheter having a proximal end in communication with the light-conducting fiber and the light-sensitive liquid, an inner lumen for passage of the light-conducting fiber, and an inner void for passage of the light-sensitive liquid; and an expandable body removably engaging a distal end of the delivery catheter, wherein the expandable body has a closed end, a sealable open end, an inner cavity for passage of the light-sensitive liquid, an external surface and an internal surface, and wherein the expandable body has an insertion depth with a fixed dimension, a width with a fixed dimension, and a thickness with a changeable dimension.

18. A method of maintaining distraction of a fractured distal radius bone comprising:
-
providing temporary distraction to a fractured distal radius bone to provide a distraction gap; delivering an expandable body in an unexpanded state into the distraction gap; infusing a first fluid into the expandable body to expand the expandable body so that a desired amount of distraction is achieved at the distraction gap; removing the first fluid from the expandable body; determining an amount of the first fluid removed from the expandable body; infusing an amount of light-sensitive liquid into the expandable body to expand the expandable body, wherein the amount of light-sensitive liquid is substantially equivalent to the amount of the first fluid; curing the light-sensitive liquid in the expandable body to form a rigid photodynamic device; and maintaining a desired amount of distraction at the distraction gap. - View Dependent Claims (19, 20)
