THE WORLD'S LEADING PROVIDER OF AMEROID CONSTRICTORS

Welcome to Research Instruments NW, the leading provider of Ameroid Constrictors. Ameroid Constrictors are used in surgical treatment when a Portosystemic Shunt has been diagnosed. The diagnosis of PSS is becoming more common as veterinarians, owners, and breeders are becoming more aware of the clinical signs.

The only treatment for a PSS is shunt ligation. Ameroid Constrictors are being used for gradual shunt ligation across the United States in many of the veterinary teaching hospitals at universities and in private practices. Internationally, we now provide Ameroid Constrictors to veterinarians in twenty-two countries.
