The US Patent and Trademark Office (USPTO) has granted new patent No. #8241330 to Lanx's Aspen MIS Fusion system, designed to support posterolateral fusions and interbody fusions.
The Aspen system features proprietary spiked fixation plates designed to be rigidly affixed to the spinous process with the use of streamlined surgical instrumentation and an offset shape for optimized anatomical fit.
In addition, the device’s central barrel allows the implant to share weight with the fixation plates while restoring foraminal height, and also serves as a bone graft containment chamber to promote fusion.
Pacific Spine Specialists spokesperson Robert Tatsumi said clinical data continues to substantiate the versatility and minimally invasive nature of the Aspen device.
"For many patients who require spinal fusion, the ASPEN device provides robust stabilization and promotes fusion while requiring a smaller incision, less muscle trauma, less blood loss, a shorter surgery time and shorter recovery time than standard pedicle screw instrumentation," Tatsumi added.
Lanx chief executive officer Dan Gladney said the Aspen system has been shown to be ideal to support fusion through a tissue-sparing technique, with over 25,000 implantations to date.
"We believe the patent granted today will support our competitive advantage as we introduce new innovations for spinal fixation and fusion, with a particular focus on less invasive treatment options like the ASPEN system," Gladney added.
