Habib™ 4X Device Yields Less Blood Loss and Shorter Operative Time in StudyQUEENSBURY, N.Y. April 2, 2009 — Sixty-eight percent less blood was lost when AngioDynamics’ Habib 4X device was used to operate on kidney malignancies compared to a control, according to a study highlighted by the company today.

The study – published in the Journal of Urology – also showed 91% fewer adverse events and a 16% shorter operative time when using the Habib 4X.

The Habib 4X – manufactured and marketed by AngioDynamics (NASDAQ: ANGO) – delivers radio frequency energy through electrode needles, coagulating tissue along a path then followed to surgically cut out and remove the lesion. By cauterizing the blood vessels excessive bleeding and other complications can be avoided compared to other methods.

“Our results show the Habib 4X radio frequency device can yield a significant benefit during open nephron sparing surgery, including reduced blood loss and a faster operative time,” said Dr. Wesley M. White, the chief author of the study. “We believe these and other key results from this study will be very helpful to physicians looking for better ways to conduct this increasingly common procedure.”

Ninety patients underwent open nephron sparing surgery, during which the surgeon resected sections of the kidney with tumors but other portions of the treated kidney were preserved. Half were treated with the Habib 4X radio frequency resection device and half with blood flow controlled with foam bolsters, suture ligation and Bovie electrocautery.

The study, titled “Nephron Sparing Surgery Using a Bipolar Radio Frequency Resection Device,” was authored by Wesley M. White, Frederick A. Klein and W. Bedford Waters from the Division of Urologic Surgery, University of Tennessee Medical Center, Knoxville, Tennessee, and published in the December edition of the Journal of Urology. “This data reinforces the meaningful improvement the Habib 4X represents over alternatives in terms of reduced blood loss, complications and operative times, providing significant advantages to both physicians and patients,” said Jan Keltjens, President and CEO of AngioDynamics. “This device is an important part of the surgical oncologist’s black bag. As the leader in radio frequency resection technology, we look forward to further controlled trials comparing radiofrequency resection versus standard treatment options to continue to reinforce the clinical benefit of this approach.”
