Systems and methods for internal bone fixation

摘要

Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. According to aspects illustrated herein, there is provided a device for repairing a fractured bone that 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.

1. A device for repairing a weakened or fractured bone 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; a balloon portion releasably engaging the distal end of the delivery catheter, 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 including a core surrounded by a cladding, the optical fiber is sized to pass through an inner lumen of the delivery catheter and into the balloon portion; wherein the core of the optical fiber is partially exposed along at least a portion of a length of the optical fiber such that, when the optical fiber is in the balloon portion, the optical fiber is configured to disperse a light energy along the portion of the length of the optical fiber to cure the at least one reinforcing material within the balloon portion.
