NuVasive Launches Latest Porous PEEK Implant for Posterior Spine Surgery

SAN DIEGO, Oct. 14, 2021 /PRNewswire/ – NuVasive, Inc. (NASDAQ: NUVA), the leader in spine technology innovation, focused on transforming spine surgery with minimally disruptive, procedurally integrated solutions, today announced the launch of the Cohere®  TLIF-O implant and upcoming launch of the Cohere TLIF-A implant planned for later in the fourth quarter. With these additions to its Advanced Materials Science™ (AMS) portfolio, NuVasive is the only company to offer both porous PEEK and porous titanium implants for posterior spine surgery.1

“NuVasive is focused on providing a comprehensive spine offering across all procedural segments to address some of the most challenging aspects of spine surgery. Porous PEEK is a clear differentiator for us in the market, and the launch of Cohere TLIF-O and future addition of Cohere TLIF-A furthers our commitment to this one-of-a-kind technology,” said Massimo Calafiore, chief commercial officer of NuVasive. “The Company has a uniquely differentiated TLIF portfolio to support the most widely used posterior spine procedure and we will continue to invest in outcome-driven innovation that drives the greatest impact for our surgeons, providers, and patients.”

Cohere TLIF-O is a porous PEEK implant for the transforaminal lumbar interbody fusion (TLIF) procedure with a variety of implant sizes to accommodate various patient anatomies and procedurally designed instrumentation. Its design adheres to NuVasive’s AMS principles of surface, structure, and imaging and includes the following features:

  • Surface: The implant’s proprietary porous surface technology generates stronger integration through bony in-growth and on-growth2 in comparison to smooth PEEK,3,4 which aids fusion and overall clinical outcomes;
  • Structure: Cohere TLIF-O is designed with lordosis in the oblique plane which helps maintain coronal alignment while restoring sagittal balance; and
  • Imaging: The radiolucent polymer composition of porous PEEK enables clear radiographic visualization of the fusion site with a variety of different imaging modalities.

“Porous PEEK combines the stiffness and radiolucency of PEEK with the enhanced osseo-integration of the porous technology—benefits not possible with prior devices,” said Frank Phillips, MD, professor of orthopedic surgery and director of the Division of Spine Surgery at Rush University Medical Center in Chicago. “The enhanced clinical outcomes possible with Cohere TLIF-O and the comprehensive surface technology options for posterior spine surgery now available are helping advance the standard of patient care.”

Later in the fourth quarter, the Company plans to launch the Cohere TLIF-A implant. While the device has similar clinical properties to Cohere TLIF-O, the Cohere TLIF-A implant is designed for anterior column support to maximize sagittal alignment correction.
