Abstract
Photodynamic bone stabilization systems are disclosed herein. In an embodiment, a photodynamic bone stabilization system includes a catheter having an elongated shaft with a proximal end adapter, a distal end releasably engaging an expandable portion, and a longitudinal axis therebetween; a light-conducting fiber configured to transmit light energy to the expandable portion; a light-sensitive liquid monomer comprising an initiator, wherein the initiator is activated when the light-conducting fiber transmits the light energy to initiate polymerization of the light-sensitive liquid monomer; and a cooling medium configured to control polymerization temperature, wherein the catheter comprises an inner void sufficiently designed to pass the light-sensitive liquid monomer into the expandable portion, and wherein the catheter comprises an inner lumen sufficiently designed to pass the light-conducting fiber into the expandable portion and configured to circulate the cooling medium.
