摘要:
An interspinous spacer comprising: a) a first brace having an upper throughhole and a lower throughhole, b) a second brace having an upper throughhole and a lower throughhole, c) a ligament having a first end and a second end, wherein the ligament extends from the upper throughhole of the first brace through the upper throughhole of the second brace.
摘要:
A two-piece fusion cage having opposed interior surfaces, vertical and lateral throughholes adapted to enhance fusion and a dovetail feature mating the opposed interior surfaces.
摘要:
A two-piece fusion cage having ramped interior surfaces. One advantage of such a cage is its easy insertion. In a first step, the lower component is inserted into the disc space and is held in place. The first step confirms placement of the implant and its footprint. In a second step, the upper component is inserted into the disc space by sliding its interior surface along the opposed interior surface of the lower component. This two-step method of insertion eliminates the need to provide an independent distraction means.
摘要:
The invention comprises flat, porous, bioabsorbable implants that are conducive to tissue ingrowth at spinal implantation site, and once absorbed, leave behind a functional ligamentous structure. A preferred material is small intestinal submucosa. Also disclosed are anchoring devices for attaching said implants to the vertebral bodies.
摘要:
This invention relates to a method and compositions for treating pathological intervertebral discs comprising the step of delivering an agent that causes chemical crosslinking of the native molecular components of the disc. Supplemental materials which are susceptible to crosslinking by the aforementioned agent are optionally delivered to the disc in order to increase and maintain disc height.
摘要:
A formed in-place spinal implant comprising a hardenable, resorbable, bone fusion-promoting composition, wherein the implant may be rigidly connected to adjacent vertebrae until fusion occurs.

摘要:
An implantable medical connector device is provided that employs a snap-on technology to safely and easily mate with another device. The medical connector device generally includes an elongate member having first and second connectors members formed on opposed ends thereof. Each connector member includes an opening formed in a sidewall thereof and extending into a nesting seat. The nesting seat is adapted to seat and engage an implanted cylindrical element.
摘要:
An in-situ formed laminoplasty implant comprising an expandable bag containing a flowable, hardenable composition, wherein the implant may be shaped to act as a laminoplasty strut and be rigidly connected to a prepared lamina space.
