True Non-Surgical Spinal Decompression System (DRX9000-SL)

The DRX9000-SL is a powered traction system designed to apply controlled decompressive forces to the lumbar spine to relieve pain and disability from low back pain and sciatica. It uses upper and lower textile harnesses, servo-motor control, and load-cell feedback to deliver smooth cyclic tension (0–150 lbs) for up to 30 minutes, allowing patients to relax completely while the device mobilizes troubled disc segments without conscious exertion.

The subject device has the same traction mechanism (electromechanical), force range (0–150 lbs pull), adjustable continuous traction speed, and 30-minute treatment duration as the predicate. The DRX9000-SL adds newer electrical safety standards (IEC 60601-1:2005 + A1:2012 + A2:2020), EMC standards (IEC 60601-1-2:2014 + A1:2020), battery backup, and specified environmental operating conditions (+10 to +40°C, 30–75% non-condensing humidity, 700–1060 hPa). Specific details of the predicate's electrical and operational specifications were not publicly available for comparison.

IEC 60601-1:2005 + A1:2012 + A2:2020 (electrical safety), IEC 60601-1-2:2014 + A1:2020 (electromagnetic compatibility), IEC 60601-1-6:2010 + A1:2013 + A2:2020 (usability), ISO 14971:2019 (risk management), ISO 10993-1:2018 (biocompatibility), and IEC 62304:2006 + A1:2015 (software life cycle). No clinical testing was performed.

The subject device and predicate share identical indications for use (lumbar low back pain and sciatica management), treatment location (lumbar spine), intended use (prescription-only in professional healthcare settings), and fundamental mechanism (electromechanical spinal decompression). Both operate within identical functional parameters: 0–150 lbs traction force, continuous adjustable speed, and up to 30 minutes treatment duration. Non-clinical testing demonstrates conformance to current international electrical safety and biocompatibility standards; since the predicate's detailed specifications were not publicly available, equivalence is established through matching functional performance, intended use, and mechanism of action rather than component-level comparison.
