Applied Spine Technologies Inc. won a patent from the U.S. Patent & Trademark Office for an element of its spinal mobility preservation device.
The USPTO awarded the patent, for a "Spinal Stabilization Device with Weld Cap," April 20, according to a press release.
The patent covers "geometry for a spring-based spinal stabilization device including members to mechanically connect the spring to other structural components," according to the release. Rocky Hill, Conn.-based Applied Spine is developing its Stabilimax dynamic spine stabilization system, which is designed to support an injured or degenerated spine without the need for a spinal fusion procedure. The system consists of two spring-loaded devices that attach to the pedicles of adjacent vertebrae.
The technology is being examined in a 100-patient clinical trial in the U.S. comparing it with traditional spinal fusion stabilization to treat degenerative lumbar spinal stenosis under an investigational device exemption from the Food & Drug Administration, according to the release.
In January the company won a patent for another element of its device, "Pedicle Screw Assembly with Bearing Surfaces," according to its website. In November 2009 the USPTO granted the company a patent for "Mounting mechanisms for pedicle screws and related assemblies."
