Abstract

Disposable light sources are disclosed herein. A device for connecting a fiber to a light source includes a light source, light director to focus light from the light source, the light director surrounding at least a portion of the light source, a power source providing energy to the light source, and a connector communicating light from the light source to a catheter.

Claims

1. A method of delivering light from a disposable light source to a remote location into a cavity of a fractured bone comprising:

delivering a bone reinforcing mixture through a catheter and into a balloon positioned in the cavity of the fractured bone at the remote location;

connecting a fiber having a distal portion to a disposable light source, wherein the light source emits light in a first direction,

providing a light director having at least one light concentrator surrounding at least a portion of the light source wherein a distal end of the at least one light concentrator is attached to a proximal end of an optical taper, the light director includes a face substantially perpendicular to the first direction, the optical taper having a distal end with a face substantially perpendicular to the emitted light and adjacent an end of the fiber;

providing a connector extending from the distal end of the optical taper that is positioned such that when the end of the fiber is inserted into an optical plug of the connector, an inner surface of the optical plug is contacted by the end of the fiber, so the fiber is aligned with the face of the optical taper, wherein the at least one light concentrator, the optical taper and the connector, each have substantially the same diameter;

positioning the distal portion of the fiber through the catheter and within the balloon containing the bone reinforcing mixture;

delivering light from the disposable light source evenly to the bone reinforcing mixture through a terminating face and along a length of the distal portion of the fiber;

curing the bone reinforcing mixture in the balloon in the cavity of the fractured bone with light emitted from the disposable light source to the distal portion of the fiber located in the balloon away from walls of the balloon, while the balloon is connected to the catheter; and

discarding the disposable light source after a single use.

2. The method of claim 1 further comprising pulsing the light from the disposable light source.

3. The method of claim 2 wherein a rate at which the light pulses is either set by a user or preprogrammed.

4. The method of claim 1 further comprising programming the disposable light source to emit a predetermined amount of energy.

5. The method of claim 1 further comprising inputting at least one variable and programming the disposable light source to emit a calculated amount of energy at a calculated rate based on the at least one variable, wherein the at least one variable includes at least one of a volume, a mass, a type and a structure of a bone reinforcing material.

6. The method of claim 1 wherein delivering the bone reinforcing mixture into the balloon engaged with the catheter that inflates and deflates in the cavity of the fractured bone.

7. The method of claim 1 wherein the bone reinforcing mixture is a light cured material.

8. The method of claim 1 wherein the bone reinforcing mixture is a light cure adhesive, and wherein the light source produces visible light.

9. The method of claim 1 wherein at least a portion of a cladding surrounding the distal portion of the fiber is removed to form a helical design in the cladding along a length of the distal portion of the fiber.

10. The method of claim 1 wherein the at least one light concentrator includes a ring that circumvents at least a majority of an outer edge of the light source, and the optical taper surrounds at least a portion of the light source, such that the ring, the optical taper or both have a light reflecting media to direct the light from a larger diameter to a smaller diameter.

11. The method of claim 10 wherein the optical taper includes a second end proximate the light source, the second end having a second face substantially perpendicular to the first direction and substantially parallel to the first face.

12. A method of delivering light from a disposable light source to a remote location inside a cavity of a fractured bone comprising:

delivering a bone reinforcing mixture through a catheter and into a balloon positioned inside the cavity of the fractured bone at the remote location;

connecting a fiber having a distal portion to a disposable light source, wherein the light source emits light in a first direction,

providing a light director having at least one light concentrator surrounding at least a portion of the light source wherein a distal end of the at least one light concentrator is attached to a proximal end of an optical taper, the light director includes a face substantially perpendicular to the first direction, the optical taper having a distal end with a face substantially perpendicular to the emitted light and adjacent an end of the fiber;

providing a connector extending from the distal end of the optical taper that is positioned such that when the end of the fiber is inserted into an optical plug of the connector, an inner surface of the optical plug is contacted by the end of the fiber, so the fiber is aligned with the face of the optical taper, wherein the at least one light concentrator, the optical taper and the connector, each have substantially the same diameter;

positioning the distal portion of the fiber through the catheter and within the balloon containing the bone reinforcing mixture;

delivering light from the disposable light source evenly along a length of the balloon through a terminating face and along a length of the distal portion of the fiber;

curing the bone reinforcing mixture within the balloon with light emitted from the disposable light source to the distal portion of the fiber located in the balloon away from walls of the balloon, while the balloon is connected to the catheter; and

discarding the disposable light source after a single use.

13. The method of claim 12 further comprising pulsing the light from the disposable light source.

14. The method of claim 13 wherein a rate at which the light pulses is either set by a user or preprogrammed.

15. The method of claim 12 further comprising programming the disposable light source to emit a predetermined amount of energy.

16. The method of claim 12 further comprising inputting at least one variable and programming the disposable light source to emit a calculated amount of energy at a calculated rate based on the at least one variable, wherein the at least one variable includes at least one of a volume, a mass, a type and a structure of a bone reinforcing material.

17. The method of claim 12 wherein the bone reinforcing mixture is a light cured material.

18. The method of claim 12 wherein the bone reinforcing mixture is a light cure adhesive, and wherein the light source produces visible light.

19. The method of claim 12 wherein positioning the fiber proximate the remote location results in positioning the fiber within the balloon that is engaged with the catheter.

20. The method of claim 12 wherein at least a portion of a cladding surrounding a distal portion of the fiber is modified to form a helical design in the cladding along a length of the distal portion of the fiber.

21. A method of delivering light from a disposable light source to a remote location within a cavity of a fractured bone comprising:

delivering a bone reinforcing mixture through a catheter and into a balloon positioned within the cavity of the fractured bone at the remote location;
