Abstract

Claims (29)

1. An apparatus for delivering a reinforcing mixture to a fractured bone, the apparatus comprising:

a balloon configured to be positioned in a cavity in a fractured bone and to expand from a deflated state to an inflated state upon a bone reinforcing mixture entering the balloon through a tube detachably coupled with a distal end of the balloon such that the inflated state of the balloon can be adjusted to place the fractured bone in a correct orientation by inflating and deflating the balloon by altering an amount of the bone reinforcing mixture in the balloon; and

at least one fiber disposed within the balloon and configured to guide a light into the balloon to cure the bone reinforcing mixture when the fractured bone has been placed in the correct orientation,

wherein the balloon, when in the inflated state by the bone reinforcing mixture in the cavity of the fractured bone, is configured to evenly contact a wall of the cavity in the fractured bone and mate with the wall of the cavity in the fractured bone.

2. The apparatus of claim 1 , the tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has one or more inner lumens extending therethrough, the balloon being configured to engage the distal end of the tube.

3. The apparatus of claim 2 , wherein the bone reinforcing mixture is configured to enter the balloon through a first lumen extending through the tube.

4. The apparatus of claim 2 , wherein the at least one fiber is configured to extend through a second lumen extending through the tube and into the balloon.

5. The apparatus of claim 1 , wherein the balloon is configured to be contoured to fit inside a cavity in a particularly shaped bone.

6. The apparatus of claim 1 , wherein an outer surface of the balloon is substantially smooth and mates with the wall of the cavity in the fractured bone.

7. The apparatus of claim 1 , wherein an outer surface of the balloon includes a textured surface.

8. The apparatus of claim 1 , wherein an outer surface of the balloon includes a convexity along its length.

9. The apparatus of claim 1 , wherein an outer surface of the balloon is coated with one or more materials, the one or more materials include at least one of a drug, a bone glue, a protein, a bone morphogenic protein, or a growth factor substance.

10. An apparatus for delivering a reinforcing mixture to a fractured bone, the apparatus comprising:

a tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has at least a first inner lumen and a second inner lumen extending therethrough;

a balloon detachably coupled to the distal end of the tube, wherein the first inner lumen of the tube extends into the balloon to pass the bone reinforcing mixture into the balloon, wherein the balloon is configured to be positioned in a cavity in a fractured bone and to expand from a deflated state to an inflated state upon the bone reinforcing mixture entering the balloon through the first inner lumen extending through the tube and into the balloon such that the inflated state of the balloon can be adjusted to place the fractured bone in a correct orientation by inflating and deflating the balloon by altering an amount of the bone reinforcing mixture in the balloon, wherein the balloon is configured to be detached from the tube when the balloon is positioned in the correct orientation; and

at least one fiber extending through the second inner lumen extending through the tube and into the balloon to guide a light into the balloon to cure the bone reinforcing mixture when the fractured bone has been placed in the correct orientation,

wherein the balloon, when in the inflated state by the bone reinforcing mixture in the cavity of the fractured bone, is configured to mate with a wall of the cavity in the fractured bone.

11. The apparatus of claim 10 , wherein the balloon is configured to be contoured to fit inside a cavity in a particularly shaped bone.

12. The apparatus of claim 10 , wherein an outer surface of the balloon is substantially smooth and mates with the wall of the cavity in the bone.

13. The apparatus of claim 10 , wherein an outer surface of the balloon includes a textured surface.

14. The apparatus of claim 10 , wherein an outer surface of the balloon includes a convexity along its length.

15. A method for reinforcing a bone comprising:

inserting a balloon into a cavity in a fractured bone;

infusing a reinforcing mixture into the balloon through an inner lumen extending through a tube and into the balloon such that the balloon expands to an inflated state, the balloon being detachably coupled to a distal end of the tube;

adjusting the inflated state of the balloon to place the bone in a correct orientation by inflating and deflating the balloon by altering an amount of the bone reinforcing mixture in the balloon such that the balloon evenly contacts a wall of the cavity and mates with the wall of the cavity in the bone, wherein the reinforcing mixture is hardened with a light delivered from a light source disposed within the balloon;

hardening the reinforcing mixture in the balloon; and

detaching the balloon from the distal end of the tube.

16. The method of claim 15 , wherein the balloon engages a distal end of the tube.

17. The method of claim 16 , wherein the reinforcing mixture is infused into the balloon through the inner lumen of the tube.
