About EMD

EMD was started by Alan Cross, DVM, Diplomate ACVS after a patient tragically died when a pop-off valve was accidentally left in the closed position. After searching and finding no acceptable way to prevent this mistake from ever happening again, he designed and manufactured the precursor to the EMD Safety Valve. After departing interns, residents, and visiting surgeons asked where to get the valves, he decided to manufacture more and sell them to the veterinary community. They are currently in use in over 100 clinics and several Universities. We hope this simple device has saved the lives of many pets.
