Abstract

Systems for the minimally invasive repair, stabilization and/or fixation of a fractured bone, such as a rib, are disclosed. The systems include one or more rods/support members that are designed to extend along a dimension of a bone being repaired and secure the fractured bone. The support members can be photodynamic and are formed using an expandable member that is filled with a light-sensitive liquid that is cured to form the rigid support member. Two or more clamps are used to secure the support member(s) to the rib or other bone. Minimally invasive surgical methods for securing the systems to a fractured bone are also disclosed.

Claims (31)

1. A bone fixation device comprising:

an expandable member capable of moving from a deflated state to an inflated state by infusing at least one curable material into the expandable member, the at least one curable material being configured to be cured within the expandable member to harden the expandable member; and

one or more clamps configured to engage a rib bone and receive the expandable member such that the one or more clamps secure the expandable member to the rib bone,

wherein the expandable member is configured to be adjustable to conform to a shape of a rib bone with the at least one curable material.

2. The bone fixation device of claim 1 , further comprising a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the expandable member being releasably engaged with the distal end of the delivery catheter.

3. The bone fixation device of claim 1 , wherein the one or more clamps include a posterior member and an anterior member.

4. The bone fixation device of claim 3 , wherein the posterior member and the anterior member are movably connected to one another between an open position such that the one or more clamps are configured to be positioned on the rib bone and a closed positioned such that the one or more clamps are configured to secure to at least a portion of the rib bone.

5. The bone fixation device of claim 1 , wherein the one or more clamps are shaped to receive the rib bone such that the one or more clamps extend around at least a portion of the rib bone.

6. The bone fixation device of claim 5 , wherein the one or more clamps include a posterior member and an anterior member, and the posterior member includes first and second arms configured to extend around a portion of a posterior side of the rib bone to secure the one or more clamps thereto.

7. The bone fixation device of claim 1 , wherein the one or more clamps include at least one contact point on a surface of the one or more clamps that is configured to contact the rib bone such that the at least one contact point is configured to increase a grip of the one or more clamps on the rib bone.

8. The bone fixation device of claim 1 , wherein the one or more clamps includes first and second clamps configured to be positioned on either side of a fracture in the rib bone.

9. The bone fixation device of claim 1 , wherein the expandable member is adjustable to conform to the shape of the rib bone to allow for a correct orientation of the rib bone.

10. The bone fixation device of claim 1 , wherein the at least one curable material is curable by light energy.

11. A bone fixation device comprising:

an expandable member releasably engaging a distal end of a delivery catheter having an inner lumen extending therethrough;

one or more clamps configured to engage a rib bone and receive the expandable member such that the one or more clamps secure the expandable member to the rib bone; and

at least one curable material;

wherein the expandable member is configured to move from a deflated state to an inflated state when the at least one curable material is added into the expandable member to allow for a correct orientation of a rib bone, and

wherein the at least one curable material is curable inside the expandable member to harden the expandable member.

12. The bone fixation device of claim 11 , wherein the one or more clamps include a posterior member and an anterior member.

13. The bone fixation device of claim 12 , wherein the posterior member and the anterior member are movably connected to one another between an open position such that the one or more clamps are configured to be positioned on the rib bone and a closed positioned such that the one or more clamps are configured to secure to at least a portion of the rib bone.

14. The bone fixation device of claim 11 , wherein the one or more clamps are shaped to receive the rib bone such that the one or more clamps extend around at least a portion of the rib bone.

15. The bone fixation device of claim 11 , wherein the one or more clamps include at least one contact point on a surface of the one or more clamps that is configured to contact the rib bone such that the at least one contact point is configured to increase a grip of the one or more clamps on the rib bone.

16. The bone fixation device of claim 11 , wherein expandable member is configured to be adjustable to allow the expandable member to conform to a shape of the rib bone with the at least one curable material.

17. The bone fixation device of claim 11 , wherein the one or more clamps includes first and second clamps configured to be positioned on either side of a fracture in the rib bone.

18. The bone fixation device of claim 11 further comprising a light fiber extending through the inner lumen into the expandable member to emit a light energy into the expandable member, wherein the at least one curable material is curable by the light energy emitted from the light fiber.

19. A method of repairing a fractured bone, comprising:

positioning one or more clamps on a rib bone, the one or more clamps including an opening configured to receive a portion of an expandable member therethrough to secure the expandable member to the rib bone;

passing the expandable member releasably engaging a delivery catheter through the opening of the one or more clamps, wherein the delivery catheter has an inner void for passing of one or more curable material to the expandable member;

expanding the expandable member by delivering at least one curable material through the delivery catheter and into the expandable member; and

adjusting the expandable member by altering an amount of the at least one curable material therein to allow for correct orientation of the rib bone.
