Systems and methods for anti-microbial effect for bones
First Claim
1. A system for providing an anti-microbial effect on a bone comprising:
- a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, an inner void for passing at least one light sensitive liquid, and an inner lumen;
an expandable member releasably engaging the distal end of the delivery catheter, the expandable member being configured to be placed into a space within a bone and capable of moving from a deflated state to an inflated state by infusing the at least one light sensitive liquid into the expandable memberat least one ridge disposed on the outer surface of the expandable member, the at least one ridge shaped longitudinally along the expandable member and extending from a first end to a second end of the expandable member;
a light conducting fiber sized to pass through the inner lumen of the delivery catheter; and
at least one channel defined in each of the at least one ridge, the at least one channel sized to accept the light conducting fiber.

Abstract
Systems and methods for restructure and stabilization of bones that provide an anti-microbial effect are disclosed herein. A device includes a delivery catheter having an inner void for passing at least one light sensitive liquid, and an inner lumen; an expandable member releasably engaging the distal end of the delivery catheter; at least one channel positioned in the expandable member; and a light conducting fiber sized to pass through the inner lumen of the delivery catheter and into the expandable member, wherein, when the light conducting fiber is in the at least one channel, the light conducting fiber is able to disperse light energy to provide an anti-microbial effect. When the light conducting fiber is in the expandable member, the light conducting fiber is able to disperse the light energy to initiate hardening of the light sensitive liquid within the expandable member to form a photodynamic implant.

9. A system for providing an anti-microbial effect on a bone comprising:
-
a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, an inner void for passing at least one light sensitive liquid, and an inner lumen; an expandable member releasably engaging the distal end of the delivery catheter, the expandable member is being configured to be placed into a space within a bone and having an outer surface and an inner surface, wherein the inner surface defines a cavity, the expandable member movable from a deflated state to an inflated state when the at least one light sensitive liquid is passed into the cavity of the expandable member; at least one ridge disposed on the outer surface of the expandable member, the at least one ridge shaped longitudinally along the expandable member and extending from a first end to a second end of the expandable member; a light conducting fiber sized to pass through the inner lumen of the delivery catheter; and one or more channel defined in each of the at least one ridge, the one or more channel sized to accept the light conducting fiber. - View Dependent Claims (10, 11)
