Systems and Methods for Internal Bone Fixation
First Claim
1. An internal bone fixation device comprising:
- a balloon portion releasably engaging a distal end of a delivery catheter, wherein an inner lumen of the delivery catheter connects to the balloon portion to guide light energy from a light source into the balloon portion;
at least one reinforcing material curable by the light energy emitted from the light source; and
one or more radiopaque markers positioned on the balloon portion,wherein the balloon portion is configured to move from a deflated state to an inflated state when the at least one reinforcing material is added into the balloon portion, andwherein the balloon portion is configured for placement into an inner cavity of a bone.

Abstract
Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. A device for use in 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 at least one reinforcing material and an inner lumen for passage of a light source; a conformable member releasably engaging the distal end of the delivery catheter, wherein the conformable member moves from a deflated state to an inflated state when the at least one reinforcing material is delivered to the conformable member; and an adapter releasably engaging the proximal end of the delivery catheter for receiving the light source and the at least one reinforcing material.

11. A system for internal fixation of a fractured bone comprising:
-
a light cure adhesive; a light pipe; a delivery catheter having an elongated shaft with a distal end and a proximal end, the delivery catheter having an inner void for passage of the light cure adhesive and an inner lumen for passage of the light pipe; and a balloon portion releasably engaging the distal end of the delivery catheter, and the balloon portion having a textured outer surface, wherein the balloon portion expands from a deflated state to an inflated state when the light cure adhesive is delivered through the inner void of the delivery catheter into the balloon portion, and wherein the inner lumen of the delivery catheter connects to the balloon portion to guide the light energy into the balloon portion to harden the light cure adhesive within the balloon portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for internal fixation of a fractured bone comprising:
-
positioning a balloon portion releasably engaging a delivery catheter within an inner cavity of a fractured bone, wherein the delivery catheter has an inner void for passage of a light cure adhesive to the balloon portion and an inner lumen for passage of a light pipe to the balloon portion; expanding the balloon portion by infusion of the light cure adhesive into the inner void of the delivery catheter and into the balloon portion; inserting the light pipe into the inner lumen of the delivery catheter and towards the balloon portion, wherein the inner lumen connects to the balloon portion to guide the light from the light pipe into the balloon portion to cure the light cure adhesive within the balloon portion; and delivering light energy through the light pipe to cure the light cure adhesive. - View Dependent Claims (25, 26)
