Nexgen Spine Inc., a New Jersey firm, has received EU approval to market its Physio-L® Lumbar Artificial Disc, a device based around polymeric elastomers. The material, according to the company, provides both strength and elasticity to better mimic natural disc performance.
From the product page:
The Physio-L™ Artificial Lumbar Disc is a weight bearing artificial intervertebral lumbar disc implant indicated for use between L3 and S1 in skeletally mature patients with degenerative disc disease (DDD). The device closely matches the physiologic properties of the intact human intervertebral disc and is comprised of a superior and inferior titanium endplate and a central elastomeric core.Single durometer poly-carbonate polyurethane core material selected for its static mechanical properties and biodurability
Elastomeric Core Geometry
1) Core deseign allows for physiologically unconstrained center of rotation and enhanced fatigue resistance.
2) Designed to restore normal range of motion n flexion/extension, lateral bending and torison.Dome Design
1) Titanium porous coated endplate dome for ingrowth.
2) 3mm high dome shape optimized to fit anatomic shape of the endplates.
3) Central keel to assist in achieving initial implant stability.
