Systems and methods for anti-microbial effect for bones
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.
1. A system for providing treatment to bone, comprising:
a delivery catheter having an elongated shaft and an inner lumen therethrough;
an expandable member positioned on a distal end of the delivery catheter, the expandable member including at least one ridge on an outermost surface thereof, the at least one ridge including at least one channel defined in the at least one ridge; and
one or more optical fibers sized to pass through the inner lumen of the delivery catheter and through the at least one channel, the one or more optical fibers being configured to directly deliver light energy to provide site-specific bone treatment of one or more pathogens,
wherein the direct delivery of light energy creates molecular oxygen for treating the one or more pathogens.
2. The system of claim 1 , wherein the light energy is delivered for about 400 seconds to provide the site-specific bone treatment.
3. The system of claim 1 , wherein the light energy is delivered for between about 400 seconds and about 800 seconds to provide the site-specific bone treatment.
4. The system of claim 1 , wherein the light energy is delivered having a wavelength from about 380 nm to about 500 nm to provide the site-specific bone treatment.
5. The system of claim 1 , wherein the light energy is delivered having a wavelength from about 400 nm to about 420 nm to provide the site-specific bone treatment.
6. The system of claim 1 , wherein the site-specific bone treatment is configured to kill the one or more pathogens.
7. A system for providing treatment to a bone, comprising:
a delivery catheter having an elongated shaft and an inner lumen therethrough;
an expandable member positioned on a distal end of the delivery catheter, the expandable member including at least one ridge on an outermost surface thereof, the at least one ridge including at least one channel defined in the at least one ridge; and
one or more optical fibers sized to pass through the inner lumen of the delivery catheter and through the at least one channel, the one or more optical fibers being configured to directly deliver light energy to provide site-specific treatment of a bone infection,
wherein the direct delivery of light energy creates molecular oxygen for treating the bone infection.
8. The system of claim 7 , wherein the light energy is delivered for about 400 seconds to provide the site-specific treatment.
9. The system of claim 7 , wherein the light energy is delivered for between about 400 seconds and about 800 seconds to provide the site-specific treatment.
10. The system of claim 7 , wherein the light energy is delivered having a wavelength from about 380 nm to about 500 nm to provide the site-specific treatment.
11. The system of claim 7 , wherein the light energy is delivered having a wavelength from about 400 nm to about 420 nm to provide the site-specific treatment.
12. The system of claim 7 , wherein the site-specific bone treatment is configured to kill the bone infection.
