SpineJet XL Instrument Ushers Era Of HydroSurgery For Spine Market

Billerica, MA - HydroCision Inc. announced that a multi-center study (using cadaver models) demonstrated that the Company's fluidjet-based instruments removed nearly 96 percent more soft tissue from the difficult-to-access posterior contralateral region than conventional surgical instruments in preparation for spinal fusion.

HydroCision's HydroSurgery system, including SpineJet XL instruments, uses a high-velocity stream of water to simultaneously cut and aspirate damaged tissue from spinal discs in preparation for fusion. The technique's advantages, illustrated by this multi-center study, include the safe and more effective removal of degenerated disc-nucleus material and endplate preparation that can lead to optimal clinical outcomes.

"Technology that allows the spine surgeon to effectively remove as much endplate cartilage as possible will facilitate interbody fusion," said Mitchell Hardenbrook, M.D., principal investigator and Director of Spine Surgery at the Naval Medical Center, Portsmouth, Va. "Our evaluations comparing HydroCision's SpineJet XL instrument to conventional surgical instruments showed that disc preparation via a HydroSurgery technique not only reduced the number of passes of the instruments compared to conventional tools but also was more effective removing disc material, thus optimizing the environment for lumbar interbody fusion."

"We are very pleased with the multi-center study that clearly positions HydroSurgery, in general, and our SpineJet XL product, in particular, as a safe and effective modality for spine surgeons--allowing them to confidently prepare a disc space more thoroughly for fusion procedures, with less collateral damage than other modalities, while minimizing the repetitive motion and fatigue currently experienced by spine surgeons using conventional tools," added Douglas J. Daniels, President and CEO of HydroCision. "We believe HydroSurgery will become a standard of care for spine surgeons performing PLIF (Posterior Lumbar Interbody Fusion), TLIF (Transforaminal Lumbar Interbody Fusion) and all MIS (Minimally Invasive Surgery) fusion procedures."
