Interventional Spine has reported that the US Patent Office (USPTO) has issued US Patent No. 7,648,523, entitled, Method and Apparatus for Spinal Stabilization. The patent includes 25 claims that provide key patent protection for Interventional Spine's PDS System, sold outside the US under the PercuDyn name.

Interventional Spine said that the patent protection strengthens the company’s patent portfolio for its key technologies, which also includes Interventional Spine’s patented ‘Clasp’ technology.

Interventional Spine’s PercuDyn System is the Percutaneous Bilateral Facet-Augmentation System for treating degenerative disc disease (DDD) and Lumbar Spinal Stenosis (LSS). With over 1,500 implants outside the US over the last three years, most in outpatient settings, the system has shown positive outcomes for patients which otherwise only alternative for treatment would have been surgery.

Walter Cuevas, chief executive officer of Interventional Spine, said: “This issuance by the US Patent Office reinforces the strength of our technologies and is one more step in our goal of making Interventional Spine a leading provider of Percutaneous technologies for the treatment of spinal disease. We are very pleased with this decision.”

California-based Interventional Spine is a privately held company that designs, develops, and markets patented implantable devices for the spine that can be deployed via percutaneous techniques, supported by the company’s product introduction systems, providing benefits to patients, surgeons and hospitals.
