Photodynamic bone stabilization and drug delivery systems
First Claim
1. A photodynamic bone stabilization and drug delivery system for repairing a fractured bone comprising:
- an insertion catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the insertion catheter having an inner void for passing at least one light-sensitive liquid, and an inner lumen;
an expandable portion releasably engaging the distal end of the insertion catheter, wherein the expandable portion comprises;
an inner expandable portion fabricated from a non-permeable material, wherein the inner expandable portion is in communication with the inner lumen of the insertion catheter and wherein the inner expandable portion is sufficiently designed to maintain a light-sensitive liquid within the inner expandable portion; and
an outer expandable portion, surrounding the inner expandable portion, sufficiently designed to house and release at least one additive from the outer expandable portion in an outward direction from the inner expandable portion and into an intramedullary canal of the fractured bone; and
a light-conducting fiber, wherein the light-conducting fiber is sized to pass through the inner lumen of the insertion catheter and into the inner expandable portion for delivering light energy to the light-sensitive liquid to cure the light-sensitive liquid within the inner expandable portion,wherein at least one of an outer surface of the inner expandable portion or an inner surface of the outer expandable portion includes a textured surface.

18. A photodynamic bone stabilization and drug delivery system for repairing a fractured bone comprising:
-
an insertion catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the insertion catheter having an inner void for passing at least one light-sensitive liquid, and an inner lumen; an expandable portion releasably engaging the distal end of the insertion catheter, wherein the expandable portion comprises; an inner expandable portion in communication with the inner lumen of the insertion catheter and sufficiently designed to maintain a light-sensitive liquid within the inner expandable portion; and an outer expandable portion, surrounding the inner expandable portion, sufficiently designed to house and release at least one additive from the outer expandable portion in an outward direction from the inner expandable portion, wherein the outer expandable portion includes one or more porous sections designed to release the at least one additive into an intramedullary canal of the fractured bone; and a light-conducting fiber, wherein the light-conducting fiber is sized to pass through the inner lumen of the insertion catheter and into the inner expandable portion for delivering light energy to the light-sensitive liquid to cure the light-sensitive liquid within the inner expandable portion, wherein at least one of an outer surface of the inner expandable portion or an inner surface of the outer expandable portion includes a textured surface. - View Dependent Claims (19)

20. A photodynamic bone stabilization and drug delivery system for repairing a fractured bone comprising:
-
an insertion catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the insertion catheter having an inner void for passing at least one light-sensitive liquid, and an inner lumen; an expandable portion releasably engaging the distal end of the insertion catheter, wherein the expandable portion comprises; a thin-walled non-compliant inner expandable portion in communication with the inner lumen of the insertion catheter sufficiently designed to stabilize the fractured bone, wherein the inner expandable portion is sufficiently designed to maintain a light-sensitive liquid within the inner expandable portion; and a thin-walled non-compliant outer expandable portion, surrounding the inner expandable portion, sufficiently designed to release at least one additive housed between the inner expandable portion and the outer expandable portion into an intramedullary canal of the fractured bone; and a light-conducting fiber, wherein the light-conducting fiber is sized to pass through the inner lumen of the insertion catheter and into the inner expandable portion for delivering light energy to the light-sensitive liquid to cure the light-sensitive liquid within the inner expandable portion, wherein at least one of an outer surface of the inner expandable portion or an inner surface of the outer expandable portion includes a textured surface.
