Medtronic Announces Launch of X-STOP(R) PEEK IPD(R) System for U.S. Patients Suffering from Symptoms of Lumbar Spinal StenosisFirst FDA-Approved Interspinous Process Decompression Device Available with a Non-metallic Polymer Interfacing with Bone
MINNEAPOLIS--(HSMN NewsFeed)--Medtronic, Inc. (NYSE: MDT ), today announced the U.S. launch of the X-STOP PEEK IPD System, the first interspinous process decompression (IPD) device approved by the U.S. Food and Drug Administration (FDA) that offers a PEEK-Bone interface for treating the symptoms of lumbar spinal stenosis (LSS). LSS is the most common reason for back surgery in people over the age of 65 in the United States.1
Polyetheretherketone (PEEK) polymer, a biomaterial widely accepted for spinal applications, provides several benefits such as biocompatibility and radiolucency (allows the passage of X-rays). Medtronic’s launch of the PEEK version, the second generation of the X-STOP system, gives spine surgeons the option of using this material in IPD procedures.
The X-STOP PEEK system is a minimally invasive treatment of the symptoms of LSS. This degenerative condition can cause compression of the spinal cord and nerves in the lower back, leading to back and leg pain or numbness that can affect mobility. An estimated 875,000 Americans are diagnosed with LSS each year, and more than two million Americans currently suffer from this disease.2
“We are extremely excited to offer the 3,200 U.S. surgeons trained so far on the X-STOP procedure the added benefits of the X-STOP PEEK system,” said Robert White, president of Kyphon products in the Spinal and Biologics business at Medtronic. “Many surgeons will welcome the properties of PEEK, the elliptical shape of the new device, and the addition of a 16 mm size implant to our X-STOP product line.”
The X-STOP PEEK system provides benefits comparable to the original X-STOP system, which was launched in the U.S. in 2006, and also includes changes in material, shape and available sizes.
- In the new system, the body of the device that is implanted between the spinous processes to prevent the pinching of the nerves is composed of a PEEK outer ring, with the remainder of the device made of titanium alloy. The original product is made completely of titanium alloy.
- The X-STOP PEEK implant has been designed to be more elliptical than the first-generation X-STOP device. This shape increases the contact area with bone by 30 percent compared to an implant of circular cross section.3 There is a broader load-bearing surface for distributing loads to the spinous processes, thereby decreasing contact pressures.
- Medtronic has also extended its product offering of X-STOP implant sizes with the addition of the 16 mm implant in the PEEK system. This larger implant size has been requested by spine surgeons for some of their patients.
Medtronic will continue to offer both the titanium and PEEK versions of the X-STOP system to accommodate the preferences of U.S. spine surgeons.
The X-STOP PEEK system will be introduced to the spine surgeon community at this year’s 23rd Annual Meeting of the North American Spine Society scheduled Oct. 14 - 18 in Toronto.
