Cement packing kyphoplasty surgical device and method
Apparatus and associated methods relate to a balloon kyphoplasty surgical device comprising an extrusion tube having internal fluid channels and a support wire, a port arrangement positioned on a proximal end of the extrusion tube and a balloon arrangement positioned on a distal end of the extrusion tube, the balloon arrangement resulting in a cubic shape when inflated by the port arrangement. An exemplary implementation may be configured with multiple inner balloons housed in an outer balloon to create a specific shape. Some designs may be configured with multiple ports designed to individually and independently inflate each inner balloon and outer balloon. The outer balloon may be inflatable. The outer balloon may be sealed off, constraining inflation of the inner balloons to create a cubic-like shape when the inner balloons are inflated within the sealed outer balloon, resulting in improved vertebral structure stabilization by increased surface area lifting the bone.
METHODS AND COMPOSITIONS FOR REPAIR OF CARTILAGE USING AN IN VIVO BIOREACTOR
Methods and compositions for the biological repair of cartilage using a hybrid construct combining both an inert structure and living core are described. The inert structure is intended to act not only as a delivery system to feed and grow a living core component, but also as an inducer of cell differentiation. The inert structure comprises concentric internal and external and inflatable/expandable balloon-like bio-polymers. The living core comprises the cell-matrix construct comprised of HDFs, for example, seeded in a scaffold. The method comprises surgically removing a damaged cartilage from a patient and inserting the hybrid construct into the cavity generated after the foregoing surgical intervention. The balloons of the inert structure are successively inflated within the target area, such as a joint, for example. Also disclosed herein are methods for growing and differentiating human fibroblasts into chondrocyte-like cells via mechanical strain.
BALLOON KYPHOPLASTY SURGICAL DEVICE AND METHOD
Apparatus and associated methods relate to a balloon kyphoplasty surgical device comprising an extrusion tube having internal fluid channels and a support wire, a port arrangement positioned on a proximal end of the extrusion tube and a balloon arrangement positioned on a distal end of the extrusion tube, the balloon arrangement resulting in a cubic shape when inflated by the port arrangement.
In-situ intervertebral fusion device and method
An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.
Self-distracting cage
Various spinal implants and methods for stabilizing the spine are provided. In one exemplary embodiment, a spinal implant is provided having an expandable container with an interior volume that is selectively expandable between a compressed condition and an expanded condition. The expandable container is coupled to a superior endplate member having a bone-contacting surface and an engagement surface effective to mate with a superior surface of the expandable container, and an inferior endplate member having a bone-contacting surface and an engagement surface effective to mate with an inferior surface of the expandable container. In addition, at least one inlet port is formed in the expandable container and is effective to communicate a fluid to at least one cavity disposed within the interior volume of the expandable container.
CORTICAL RIM-SUPPORTING INTERBODY DEVICE AND METHOD
An inflatable central distractor is inserted in to a disc space between two vertebral endplates. A perimeter balloon is inserted into the disc space in such a manner as to surround the central inflatable distractor. The perimeter balloon and the central inflatable distractor are simultaneously expanded such that as the central inflatable distractor expands the perimeter balloon surrounds the central inflatable distractor and such that the central inflatable distractor and the perimeter balloon, when expanded, contribute to forcing adjacent vertebral endplates apart.
Prosthetic spinal disk nucleus
This specification describes technologies relating to an intervertebral disc prosthesis used to strengthen and stabilize the spine. Implementations of the technology described herein comprise a surgical device that is implanted through a small surgical incision into a portion of a human intervertebral disc, various support tools used to insert such a surgical device, and a method by which the device is used to strengthen and stabilize the spine.
Cortical rim-supporting interbody device and method
An inflatable central distractor is inserted in to a disc space between two vertebral endplates. A perimeter balloon is inserted into the disc space in such a manner as to surround the central inflatable distractor. The perimeter balloon and the central inflatable distractor are simultaneously expanded such that as the central inflatable distractor expands the perimeter balloon surrounds the central inflatable distractor and such that the central inflatable distractor and the perimeter balloon, when expanded, contribute to forcing adjacent vertebral endplates apart.
