DEVICES AND METHODS FOR BONE RESTRUCTURE AND STABILIZATION

摘要

Devices (100) and methods for restructure and stabilization of a fractured or weakened head of a bone are disclosed herein. A device (100) includes a delivery catheter (150) having a proximal end and a distal end, an inner void for passing at least one light sensitive liquid (165), and an inner lumen; an expandable member (170) releasably engaging the distal end of the delivery catheter (150); and a light conducting fiber (140) sized to pass through the inner lumen of the delivery catheter (150) and into the expandable member (170). The expandable member (170) moves from a deflated state to an inflated state when the light sensitive liquid (165) is passed to the expandable member (170). The light conducting fiber (140) is able to disperse the light energy to initiate hardening of the light sensitive liquid (165) within the expandable member (170) to form a photodynamic implant (510).
