Abstract

Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. In an aspect, a device for repairing a fractured bone includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the delivery catheter having an inner void for passing at least one reinforcing material, and an inner lumen for accepting a light pipe, wherein a distal end of the inner lumen terminates in an optical lens; a conformable member releasably engaging the distal end of the delivery catheter, the conformable member moving 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 pipe and the at least one reinforcing material.

Claims

1. An internal bone fixation device comprising:

a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the delivery catheter having an inner void for passing at least one reinforcing material, and an inner lumen;

a balloon portion extending from the distal end of the delivery catheter, wherein the balloon portion is expandable from a deflated state to an inflated state by adding the at least one reinforcing material into the balloon portion; and

an optical fiber sized to pass through the inner lumen of the delivery catheter and into the balloon portion, wherein a core of the optical fiber is modified such that, when the optical fiber is in the balloon portion, the optical fiber is able to disperse the light energy along at least a portion of the length of the optical fiber to cure the at least one reinforcing material within the balloon portion.

2. The device of claim 1 further comprising a cladding surrounding the core of the optical fiber.

3. The device of claim 2 wherein the core of the optical fiber is exposed by removing a portion of the cladding.

4. The device of claim 2 wherein a distal portion of the optical fiber is modified by cutting at least one notch into the cladding to expose the core of the optical fiber.

5. The device of claim 1 wherein a distal portion of the optical fiber is modified by removing varying amounts of a cladding along the distal portion to create one or more terminating faces to disperse the light energy.

6. The device of claim 1 wherein a distal portion of the optical fiber is modified by removing a cladding from the optical fiber to create a helical design on a surface of the optical fiber to disperse the light energy along the length and at a distal end of the optical fiber in a helical pattern.

7. The device of claim 1 further comprising an adapter releasably engaging the proximal end of the delivery catheter for receiving the optical fiber and the at least one reinforcing material.

8. The device of claim 1 further comprising an optical lens that transmits the light energy from the optical fiber to the balloon portion.

9. The device of claim 1 further comprising one or more illuminators within the core of the optical fiber.

10. The device of claim 1 further comprising a light source for providing the light energy to the optical fiber.

11. An internal bone fixation device comprising:

a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the delivery catheter having an inner void for passage of at least one reinforcing material, and an inner lumen;

a balloon portion extending from the distal end of the delivery catheter, the balloon portion expandable from a deflated state to an inflated state by passing the at least one reinforcing material into the balloon portion; and

an optical fiber sized to pass through the inner lumen of the delivery catheter and into the balloon portion, wherein, when the optical fiber is in the balloon portion, the optical fiber disperses the light energy in a radial direction to cure the at least one reinforcing material within the balloon portion.

12. The device of claim 11 wherein the optical fiber disperses the light energy along a length of the optical fiber.

13. The device of claim 11 wherein the optical fiber includes a core surrounded by a cladding.

14. The device of claim 13 wherein the output end is tapered by removing a portion of the cladding surrounding the core along a length of the optical fiber.

15. The device of claim 11 further comprising one or more illuminators within a core of the optical fiber.

16. The device of claim 11 further comprising an optical lens that transmits the light energy from the optical fiber to the balloon portion.

17. The device of claim 11 further comprising a light source for providing the light energy to the optical fiber.

18. A kit for repairing a weakened or fractured bone, the kit comprising:

an optical fiber, wherein at least a distal portion of the optical fiber is modified, and wherein the distal portion of the optical fiber is configured to disperse light energy at along at least a portion of a length of the distal portion of the optical fiber;

at least one reinforcing material; and

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 passing the at least one reinforcing material into a balloon portion extending from the distal end of the delivery catheter, and wherein the delivery catheter has an inner lumen for passing the optical fiber into the balloon portion.

19. The kit of claim 18 further comprising an adapter to be releasably engaged to the proximal end of the delivery catheter for receiving the optical fiber and the at least one reinforcing material.

20. The kit of claim 18 further comprising a light source for providing the light energy to the optical fiber.
