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. 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.

主权项

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; andan 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.
