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;
at least one inner lumen incorporated within the elongated shaft;
at least a first inner inflatable balloon positioned inside and completely surrounded by an outer inflatable balloon, the balloons located at the distal end; and
an adapter for passage of at least one of an inflation fluid or a medical instrument, the adapter located at the proximal end; and
an optical fiber having a core surrounded by a cladding material, the optical fiber comprising;
an outer diameter sized to pass through the inner lumen of the elongated shaft of the balloon catheter;
a nonlinear light-emitting portion of a given length, wherein a portion of the 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.

11. A system comprising:
-
a balloon catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the balloon catheter comprising; at least one inner lumen incorporated within the elongated shaft; at least a first inner inflatable balloon positioned inside and completely surrounded by an outer inflatable balloon, the balloons located at the distal end; and a multipurpose adapter for passage of at least one of an inflation fluid or a medical instrument, the multipurpose adapter located at the proximal end; an optical fiber having a core surrounded by a cladding material, the optical fiber comprising; an outer diameter sized to pass through the inner lumen of the elongated shaft of the balloon catheter; a nonlinear light-emitting portion of a given length, wherein a portion of the 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; a linear elongated portion for guiding light towards the nonlinear light-emitting portion; a relaxed condition in which the nonlinear light-emitting portion of the optical fiber assumes a curved conformation; 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 the inner lumen of the elongated shaft of the balloon catheter; and a memory which returns the nonlinear light-emitting portion from the stretched condition to the relaxed condition; a light-sensitive fluid; and a light source. - View Dependent Claims (12, 13, 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 having a first inner balloon positioned inside and completely surrounded by an outer balloon; injecting an inflation fluid into the outer balloon to expand the outer balloon and to temporarily restore height of the collapsed vertebrae; maintaining the expanded outer balloon while injecting a light-curable fluid into the inner balloon to expand the inner balloon within the expanded outer balloon; positioning an optical fiber sufficiently designed to emit light energy along a length of the optical fiber inside the expandable member, wherein the optical fiber is connected to a light source; activating the light source; delivering light energy to the optical fiber from the light source; and curing the light-curable fluid inside the inner balloon to harden the inner balloon within the expanded outer balloon. - View Dependent Claims (20)
