New Aids for Spinal Surgery

New aids and devices specially designed for minimally disruptive surgical treatments for the spine have been announced by NuVasive, Inc. (San Diego, CA, USA).

MaXcess II, an enhancement of the MaXcess system, features three blades that slide down over NuVasive's NeuroVision dilators and gently spread apart the patient's tissue. The superior and inferior blades "kick-out” at an angle, spreading the tissue closest to the pathology point. MaXcess II also allows for greater exposure and access to the spine while requiring no greater incision, and offers a retraction system that is radiolucent or translucent to x-rays, giving the surgeon a full view of the pathology point during fluoroscopy.

CoRoent large contoured implant and CoRoent XLR systems are designed to allow for simplicity of surgeon placement and proper anatomical fit in the spine. Both are radiolucent and include radio-dense titanium markers, enabling the surgeon to visually confirm their correct positioning. These products are made of Peek Optima, a biocompatible polymer commonly used in implantable devices.

NuVasive has also made enhancements to its NeuroVision nerve-avoidance system in the form of a software upgrade and improved nerve-monitoring capabilities. NeuroVision has also been given a new harness and dual electrodes to streamline the application of surface electrodes that relay muscle activity to the nerve-monitoring system.

"We are particularly excited about the launch of MaXcess II, which we believe provides surgeons with the greatest access to the spine in a minimally disruptive procedure available on the market,” said Alexis V. Lukianov, chairman and CEO of NuVasive.
