Distal Tip for Bone Fixation Devices

A system for bone fixation comprising:

• a delivery catheter having a proximal end and a distal end;
• an expandable member having a proximal region and a distal region, wherein the expandable member is releasably attached about the distal end of the delivery catheter at the proximal region of the expandable member;
• a distal cap attached to the distal region of the expandable member to seal the expandable member;
• a light conducting fiber;
• and
• a light-sensitive liquid;
• wherein the delivery catheter has an inner void for passage of a light-sensitive liquid into the expandable member to expand the expandable member and an inner lumen for passage of the light conducting fiber into the expandable member to cure the light-sensitive liquid inside the expandable member.

A method for bone fixation comprising:

• advancing to a fractured bone a device comprising:
• a delivery catheter having a proximal end and a distal end;
• an expandable member having a proximal region and a distal region, wherein the expandable member is attached about the distal end of the delivery catheter at the proximal region of the expandable member;
• and
• a distal cap attached to the distal region of the expandable member to seal the expandable member
• positioning the expandable member within an intramedullary cavity of the fractured bone;
• expanding the expandable member with a light-sensitive liquid;
• and
• curing the light-sensitive liquid within the expandable member.
