German medical device firm Joimax has expanded its invasive endoscopic spinal surgery portfolio with the introduction of two new products, EndoLIF On-Cage and iLESSYS Delta interlaminar system.


EndoLIF is a 3D-printed titanium alloy that is developed using a special electron beam melting (EBM) technology.

In July, the firm obtained 510(k) approval from the US Food and Drug Administration (FDA) for the Endoscopic Lumbar Interbody Fusion or EndoLIF On-Cage implant. It also received FDA approval for Percusys percutaneous screw-rod-system at the starting of the year.

The system has a porous surface with a diamond cell structure, offering an optimal base for cell proliferation and bone growth.

Filled with an autogenous bone, the system’s two large implant graft windows allow for bridging bone to further support fusion.

EndoLIF On-Cage implant enables surgeons to use a mini-open or an inter-muscular approach into the intervertebral disc space, allowing for endoscopic-assisted fusion.

The inter-muscular approach is similar to a mini-transforaminal lumbar interbody fusion (TLIF) approach.

The firm’s iLESSYS Delta system can be used for dorsal and dorso-lateral treatment of central spinal canal stenosis.

The new and specific instrument set comprises newly developed tools, which allow an extensive and tissue-sparing decompression.

A new endoscope with a 6mm working channel enables the use of large shaver blades developed for bone and tissue resection and other instruments can be used under full endoscopic view.

Joimax CEO and founder Wolfgang Ries said: "Albert Telfeian and Jian Shen will be the first spinal surgeons in the USA to perform surgeries with the new iLESSYS Delta endoscopic technology and the EndoLIF On-Cage implants."

The company is exhibiting the EndoLIF system at the 30th annual North American Spine Society (NASS) meeting in Chicago, which is being held from 14 to 17 October.
