Systems and Methods for Treating Conditions and Diseases of the Spine
First Claim
1. A device comprising:
- a balloon catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the balloon catheter comprising;
a balloon located at the distal end of the balloon catheter;
an optical fiber comprising a nonlinear light-emitting portion configured to emit light energy along the length of the nonlinear light-emitting portion; and
a linear elongated portion for guiding light towards the nonlinear light-emitting portion,wherein the optical fiber has a linear conformation in which the nonlinear light-emitting portion of the optical fiber can be advanced through the elongated shaft of the balloon catheter into the balloon and a curved conformation in which the nonlinear light-emitting portion of the optical fiber can curve inside the balloon.

Abstract
Systems and methods for treating conditions and diseases of the spine are disclosed herein. A device includes a balloon catheter comprising at least one inner lumen incorporated within an elongated shaft; a distal end having an inner balloon positioned inside and completely surrounded by an outer balloon; and a proximal end having an adapter for passage of at least one of an inflation fluid or a medical instrument; and an optical fiber comprising an outer diameter sized to pass through the inner lumen of the elongated shaft; a nonlinear light-emitting portion of a given length, wherein a portion of a cladding material from the nonlinear light-emitting portion has been removed so that light energy may be emitted along the length of the nonlinear light-emitting portion; and a linear elongated portion for guiding light towards the nonlinear light-emitting portion.

13. A system for treatment of an intervertebral disc comprising:
-
a balloon catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the balloon catheter comprising; a balloon located at the distal end of the balloon catheter; an optical fiber having a core surrounded by a cladding material, the optical fiber comprising a nonlinear light-emitting portion configured to emit light energy along the length of the nonlinear light-emitting portion and a linear elongated portion for guiding light towards the nonlinear light-emitting portion; wherein, the optical fiber has a relaxed condition in which the nonlinear light-emitting portion of the optical fiber assumes a curved conformation, in which the nonlinear light-emitting portion of the optical fiber curves inside the balloon and has a stretched condition in which the nonlinear light-emitting portion of the optical fiber has a linear conformation in which the nonlinear light-emitting portion of the optical fiber can be advanced through an inner lumen of the elongated shaft of the balloon catheter; a light-sensitive fluid; and a light source. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for repairing a vertebral compression fracture comprising:
-
gaining access to a collapsed vertebrae; delivering to the collapsed vertebrae, in an unexpanded state, an expandable member; injecting a light-curable fluid into the expandable member; positioning an optical fiber along a length inside the expandable member, wherein the optical fiber is connected to a light source and is configured to emit light energy; delivering light energy to the optical fiber from the light source; and curing the light-curable fluid inside the expandable member to harden the light-curable fluid. - View Dependent Claims (20)
