Abstract:
1. A system for forming a photodynamic joint spacer, the system 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 light-sensitive liquid therethrough; an expandable member releasably engaging the distal end of the delivery catheter, the expandable member moveable from a deflated state to an inflated state when the at least one light-sensitive liquid enters the expandable member, wherein the expandable member is sufficiently designed to engage a bone; a formable bar configured for attachment to the bone adjacent the expandable member to shape the expandable member into a desired shape; and a light conducting fiber for providing light energy to the light-sensitive liquid within the expandable member to cure the light-sensitive liquid within the expandable member to set the expandable member in the desired shape to form a photodynamic joint spacer.
