HydroCision Receives Two Additional FDA 510(k) Clearances for SpineJetTM

ANDOVER, Mass., January 9, 2003 – HydroCision, Inc. (www.hydrocision.com) announced today that the United States Food and Drug Administration has granted 510(k) clearances to market its fluidjet-powered burr and its bipolar electrocautery devices for open and minimally invasive spine surgery. These regulatory clearances follow prior European Union CE Mark certification and a prior U.S. regulatory approval of a fluidjet-based soft tissue resection device for indications in the spine.

The SpineJet system combines selective removal of soft tissue, such as the nucleus and annulus, with electrocautery to control bleeding in the surgical field without having to exchange instruments. The high-speed fluidjet-powered burr will further enable spine surgeons to shape and remove hard tissue such as the lamina and bone while maximizing control during their procedures.

“These two new product offerings will provide the spine surgeon and their patients with a significant advancement for open and minimally invasive discectomy procedures”, commented Doug Daniels, President of HydroCision, Inc. “We believe the fluidjet-based hydrosurgery system is a significant advancement in the spine surgeons’ surgical tools and will enable them to perform a number of existing and new spine procedures more effectively, with greater ease, and with improved economic outcomes.” HydroCision plans to enter the US and European MIS spine markets in the second half of 2003.
