Abstract
An inflatable and implantable balloon for treatment of degenerative disc disease, bones, lesions, spinal deformities and spinal motion segment instabilities. The balloon is comprised of adjustable and expandable volumes. Further disclosed are methods of forming, inserting, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the spinal lesion or disease. Still further disclosed are kits for aligning and stabilizing elements of the spine.
Claims25
A multi-volume balloon for treating clinical consequences of degenerative disc disease, vertebral body bone defects, and spinal motion segment instability comprising a plurality of single volumes each connected, directly or indirectly, to one another, wherein a perforation site is located between at least two of the single volumes, and wherein each single volume is individually adjustable and expandable such that (a) each single volume can contain a variable volume of contents, and (b) each of the plurality of single volumes can contain the same, or a different, amount and type of contents relative to another single volume.
A balloon for treating clinical consequences of degenerative disc disease, vertebral body bone defects, and spinal motion segment instability comprising at least two pieces of material that are bonded together to form a balloon, wherein the material contains marks, wherein the marks can be bonded together to form at least two compartments in the balloon.
A method of angling a single-volume balloon to create a multi-volume balloon, the method comprising:
- providing a single-volume balloon;
- providing at least one ring, wherein the ring has two ends and the ends of the ring are set to a predetermined angle;
- inserting the single-volume balloon into the ring;
- inserting the ring containing the single-volume balloon into a cavity of a vertebral column, wherein the cavity is selected from the group consisting of an intervertebral disc space and a space in a vertebral body;
- and
- expanding the single-volume balloon, wherein the expansion of the single-volume balloon within the ring forms a multi-volume balloon with the predetermined angle of the ring determining the angulation of each volume of the multi-volume balloon.
A method of aligning and stabilizing a vertebral column, the method comprising:
- inserting a balloon-catheter containing a multi-volume balloon, wherein the multi-volume balloon is located at the distal end of the balloon-catheter, into a cavity of a vertebral column, wherein the cavity is selected from the group consisting of an intervertebral disc space and a space in a vertebral body;
- expanding a first volume of the multi-volume balloon by inserting a fluid, wherein the expansion of the first volume restores height to the vertebral column;
- and
- expanding a second volume of the multi-volume balloon by inserting a solidifying material, wherein the solidifying material hardens after insertion to maintain the height restoration created by the expansion of the first volume.
A method for inserting a balloon into a cavity of a patient, the method comprising:
- rolling the balloon into a tubular shape;
- inserting the balloon into the cavity of the patient, wherein the cavity was cleared prior to insertion of the balloon;
- and
- unfurling the balloon once inside the cavity.
A kit for aligning and stabilizing a bone, the kit comprising:
- at least one single-volume balloon;
- and
- at least one ring, wherein each ring has two ends, the ends of the ring are set to a predetermined angle, the single-volume balloon is inserted into the ring, wherein inflating the single-volume balloon containing the ring creates a multi-volume balloon, and the predetermined angle of the ring determines the angulation of each volume of the multi-volume balloon.
