HydroCision Launches SpineJet™ Curette and SpineJet Resector XT
at AAOS in San Francisco

Release of the SpineJet Curette and SpineJet Resector XT Offer Potential for Faster Procedures, Greater Patient Safety and Procedural Efficiency

SAN FRANCISCO, CA; ANDOVER, Mass., March 10, 2004 —HydroCision, Inc., the leading provider of Hydrosurgery devices, announced today the release of two new handpieces as part of its SpineJet Hydrosurgery System - the SpineJet Curette and the SpineJet Resector XT. The addition of these two products to the SpineJet family broadens the scope of HydroCision’s product applications allowing the spine surgeon to perform fusion procedures fast, safe, and effectively.

The SpineJet Curette combines the mechanical advantage of a serrated edge tip with the tissue evacuation capabilities of a fluidjet. The spine surgeon can simultaneously remove soft tissue, such as disc nucleus, and scrape vertebral endplates quickly and without the repeated instrument passes by vital structures such as nerves and vessels. These improvements in HydroCision's SpineJet devices enhance the spine surgeon's capabilities in the essential tasks necessary for preparing the disc space prior to spinal fusion.
The SpineJet Resector XT provides access to the hard-to-reach areas of the disc space allowing the spine surgeon the opportunity to remove more of the disc nucleus in fusion procedures.

”The SpineJet Curette helps me perform spine procedures faster and more effectively because it gives me the mechanical advantage of a sharp curette while simultaneously removing tissue from the operative site", states Dr. John Cobb, Orthopedic Spine Surgeon at the Lafayette Bone and Joint Clinic, in Lafayette, Louisiana. “Using one device for both functions allows me to reduce surgical time. The device is perfectly angled to access and remove tissue from the lateral gutters in preparation for rod and screw placement. This is an exciting new technology that has the ability to greatly enhance the care of my patients."

“The SpineJet Curette is the key product platform for HydroCision," commented Doug Daniels, President and CEO of HydroCision, Inc. "These devices will enable spine surgeons to perform fast, safe, and effective tissue resection and removal in a variety of spine procedures. The SpineJet Curette provides a single instrument for the spine surgeon to effectively prepare the interbody space for spinal fusion or artificial discs. The spine market is the key strategic market for HydroCision. The launch of these new SpineJet devices continues to strengthen our leadership position in fluidjet technology. We look forward to showing our technology to leading spine surgeons at AAOS."
HydroCision will showcase its SpineJet Hydrosurgery System – featuring the SpineJet Curette and the SpineJet Resector XT – at the upcoming American Academy of Orthopedic Surgeons (AAOS) meeting, beginning March 10th, in booth #2709.
