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. A device for use in repairing a fractured bone includes 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 passage of at least one reinforcing material and an inner lumen for passage of a light source; a conformable member releasably engaging the distal end of the delivery catheter, wherein the conformable member moves 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 source and the at least one reinforcing material.

主权项

1. An internal bone fixation device comprising:
a balloon portion releasably engaging a distal end of a delivery catheter, wherein an inner lumen of the delivery catheter connects to the balloon portion to guide light energy from a light source into the balloon portion; at least one reinforcing material curable by the light energy emitted from the light source; and one or more radiopaque markers positioned on the balloon portion, wherein the balloon portion is configured to move from a deflated state to an inflated state when the at least one reinforcing material is added into the balloon portion, and wherein the balloon portion is configured for placement into an inner cavity of a bone.
