HydroCision's novel fluidjet system for Disc Preperation in Lumbar Interbody Fusion to be presented to surgical community

Billerica , Mass. , July 5, 2005 – A breakthrough fluidjet technology introduced last year by HydroCision to treat degenerated spinal discs is poised for international exposure to the medical community. A paper titled “Evaluation of a Novel Hydrosurgery System for Disc Preparation in Lumbar Interbody Fusion in a Cadaver Model” will be presented to surgeons and medical scientists at the 12th International Meeting of Advanced Spine Technology (IMAST) in Banff , Alberta , Canada on July 7-9, 2005.

The paper, authored by Dr. Ali Araghi (Texas Back Institute) and others, presents the effectiveness of Hydrosurgery in removing spinal disc nucleus material and preparing the disc endplate for spinal fusion.

HydroCision's Hydrosurgery™ system, including SpineJet XL instruments, uses a high velocity stream of water to simultaneously cut and asperate out damaged tissue from spinal disc nucleus in preparation for fusion. The technique's advantages include effective removal of degenerated tissue and optimal endplate preparation that can lead to better outcomes.
