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:
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 intervertebral fusion device comprising inferior and superior fusion cage devices that provide an ability to correct spondylolisthesis via in-situ adjustment.
摘要:
A self-retaining neural retraction clip, preferably having controlled retraction level and an off-set retraction means. This device can reduce operative site clutter to enhance disc access while providing consistent and stable dural retraction.
