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.

First claim

What is claimed:

1. 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 connected to one another along a perforation site located between two adjacent single volumes that provides a pre-determined breaking point between the single volumes, 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; and
wherein the perforation site is configured to decouple a guidewire attached to the multi-volume balloon by tearing the two adjacent single volumes apart at the perforation site; and
wherein the guidewire is decoupled with an outer volume of the plurality of single volumes at the perforation site.

2. The multi-volume balloon according to claim 1 , wherein the single volumes are compartments of at least two pieces of foil bonded together at the perforation site, wherein the bonding is selected from the group consisting of: ultrasonic welding, thermal welding using a light source, thermal welding using a heat source, pressure welding, swaging, joining, gluing, and stitching.

3. The multi-volume balloon according to claim 1 , wherein a material of the plurality of single volumes is selected from the group consisting of: foil, mesh, tube, silicone rubber, elastomeric rubber, polyether ether ketone (or PEEK), polyether ketone ketone (or PEKK), polyethelyene (or PE), polyethelyene terephthalate (or PET), polyurethane (or PU), thermoplastic polyurethane (or TPU), and polycarbonate urethane (or PCU).

4. 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 connected to one another along a perforation site located between two adjacent single volumes that provides a pre-determined breaking point between the single volumes, 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,
wherein the single volumes are compartments of at least two pieces of foil bonded together at the perforation site, wherein the bonding is selected from the group consisting of: ultrasonic welding, thermal welding using a light source, thermal welding using a heat source, pressure welding, swaging, joining, gluing, and stitching.
