Pinnacle Spine launches Infill anterior lumbar interbody fusion device

189

Pinnacle Spine has launched its InFill anterior lumbar interbody fusion (ALIF) interbody device. The device is designed to maximise wall thickness and graft chamber volume, ensuring optimal contact with the vertebral endplates by both the interbody device and bone graft material.

The InFill ALIF device is designed to be used with Pinnacle’s InFill graft delivery system, which is allows surgeons to deliver the optimal volume of graft material to the implant in situ without disrupting the interbody device’s placement, providing an opportunity to achieve maximum bone graft-to-endplate contact.

According to a press release, the ALIF device exhibits the following features:

  • Designed for optimal use of the L5/S1 disc space
  • A gently bulleted nose to assist ease of insertion
  • The option for in situ delivery of bone graft material intended to ensure a more complete fill
  • A large graft chamber which designed to facilitate formation of a robust fusion column
  • An aggressive tooth design intended to prevent displacement of the device
  • A large surface area designed to provide maximum contact with the apophyseal ring, with the aim of restoring and maintaining disc space and height
  • Tantalum rod markers intended to promote radiographic visualisation of interbody device orientation and placement.

Pinnacle recently announced its first international patent, a Chinese patent, which followed receipt of three US patents on the InFill fusion system.
