Abstract
An inflatable balloon for diagnostics and treatment of diseased discs or fractured bones. The balloon is a multi-volume balloon comprised of a plurality of adjustable and expandable single volumes. Further disclosed are methods of forming, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the diseased discs or fractured bones. Still further disclosed are kits for aligning and stabilizing a bone, disc, or spinal motion segment.
Claims20
A multi-volume balloon for treating the 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 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 method for treating the clinical consequences of degenerative disc disease, vertebral body bone defects, and spinal motion segment instability, the method comprising:
- inserting an unexpanded multi-volume balloon having a proximal end and a distal end, wherein the multi-volume balloon contains a perforated guide tube, into a cavity of a vertebral column, wherein the cavity is selected from the group consisting of an intervertebral disc space, an interspinous space, and a space in a vertebral body;
- inserting an inner tube into the perforated guide tube at an insertion site, wherein the inner tube is attached to a delivery tube;
- securing the delivery tube to the perforated guide tube to create a seal at the insertion site;
- expanding a first volume of the multi-volume balloon most distal from the insertion site by providing contents to the first volume of the multi-volume balloon through the inner tube wherein the volume of contents delivered is adjustable and variable and wherein the expansion provides a correction to the vertebral column;
- retracting the inner tube to a second more proximal volume of the multi-volume balloon;
- expanding the second more proximal volume of the multi-volume balloon by providing contents to the second more proximal volume through the inner tube wherein the expansion provides a further correction to the vertebral column;
- retracting the inner tube from the perforated guide tube;
- sealing the insertion site;
- and
- determining the total correction made to the vertebral column by the expansion of the multi-volume balloon.
A method of guiding and implanting a multi-volume balloon for treating the clinical consequences of degenerative disc disease, vertebral body bone defects, and spinal motion segment instability, the method comprising:
- inserting a first single-volume balloon into an insertion site of a cavity of a vertebral column, wherein the cavity is selected from the group consisting of an intervertebral disc space, a space in a vertebral body, and an interspinous space, wherein the first single-volume balloon includes a first ring on the proximal end of the single-volume balloon;
- connecting a delivery tube to the first ring;
- expanding the first single-volume balloon with contents delivered through the delivery tube;
- sealing off the expanded first single-volume balloon with the first ring;
- inserting a second single-volume balloon in the insertion site of the cavity of the vertebral column, wherein the first ring around the first single-volume balloon guides the insertion of the second single-volume balloon;
- puncturing the expanded first single-volume balloon through the first ring;
- inserting a distal portion of the second single-volume balloon into the first single-volume balloon via the puncture site through the first ring;
- connecting the delivery tube to a second ring on the proximal end of the second single-volume balloon;
- expanding the second single-volume balloon with contents delivered through the delivery tube wherein the distal portion of the expanded second single-volume balloon is expanded within the first single-volume balloon, the first ring around the first single-volume balloon creates a seal between the expanded second single-volume balloon and the expanded first single-volume balloon, and the connected first and second single-volume balloons form a multi-volume balloon;
- sealing the expanded second single-volume balloon with the second ring;
- and
- determining a correction made to the vertebral column from the inflation of the first and second single-volume balloons.
A kit for aligning and stabilizing a bone, the kit comprising,
- a multi-volume balloon including a plurality of adjustable single-volume balloons each connected, directly or indirectly, to one another, wherein each single-volume balloon is individually adjustable and expandable such that (a) each single-volume balloon can contain a variable volume of contents, and (b) each of the plurality of single-volume balloons can contain the same, or a different, volume of contents relative to another single-volume balloon;
- a perforated guide tube contained within the multi-volume balloon;
- an inner tube adapted to be inserted into the perforated guide tube wherein the inner tube is capable of delivering contents to the plurality of single-volume balloons;
- and
- a delivery tube adapted to be connected both to the inner tube and to the perforated guide tube.
