EIT 3D Printed Cervical Cage

Emerging Implant Technologies GmbH (EIT) announced the U.S. Food and Drug Administration (FDA) clearance of the expansion of the label of their EIT Cellular Titanium® Cervical Cage to be used in multiple contiguous cervical levels (C2 to T1).

EIT Cellular Titanium® is a 3D printed porous titanium structure that has been designed according to scientific insights on ideal pore shape and size to optimize cell proliferation and bone ingrowth. The anatomical design of the EIT cervical cage assists the surgical and biomechanical challenges of cervical multi-level fusion by adapted to maximized vertebral endplate contact and sagittal balance restoration.

The fusion potential of the implants is supported by EIT’s proprietary 3D process including post-printing etching procedures, allowing for unique porous structures that are impossible to manufacture with traditional manufacturing techniques. “This is another important regulatory milestone for EIT,” said Guntmar Eisen, Founder and CEO of EIT. “Only very few cervical cages are approved for multilevel use and we are poised to quickly enter the US market with the most advanced technology and state of the art FDA labeling and compliance.”

This marks the first multi-level 3D printed cervical cage to enter the US market. The EIT cervical cage is to be used with supplemental fixation and designed for use with autogenous and/or allogenic bone graft to facilitate fusion. Musculoskeletal Clinical Regulatory Advisers, LLC (MCRA), assisted EIT on the FDA strategy and submission. Justin Eggleton, Senior Director of Regulatory Affairs commented “this clearance represents continued synergy between FDA and the medical community. The expanded indications to multiple levels in the cervical spine facilitates improved surgeon collaboration and the ability to collect data that will strengthen the total product lifecycle, which ultimately benefits patients.”

The company’s plans to complete the current product portfolio with a lateral lumbar cage in Q2 and a fully printed lateral expanding cage in Q4.
