MINNEAPOLIS, MN--(Marketwire - July 28, 2011) -

BioDrain Medical, Inc. (OTCBB: BIOR) (OTCQB: BIOR), producer of the FDA cleared Streamway® System for automated surgical fluid disposal, announced today two additional patents are pending for the Streamway System. This is in addition to the three issued patents for the Streamway System covering the United States, Europe, and Canada.

Chad Ruwe, Chief Operating Officer of BioDrain Medical Inc., said, “We continue to invest in our intellectual property portfolio and are pleased to see the steady progress of our filings for a Divisional Patent and a Continuation-In-Part Patent that are pending and under review by the United States Patent & Trademark Office.”

Kevin Davidson, CEO of the Company, added, “The rapid acceptance of our system in hospitals heightens our awareness of the importance of having the highest possible level of patent protection. While our present patent portfolio is strong, these two additional steps expand our claims to cover recent enhancements to the system and also extend the effective protection of the original patents.”

About BioDrain Medical, Inc.
BioDrain Medical, Inc. has a fully automated, patented, FDA cleared, surgical fluid management system that virtually eliminates operating room workers’ exposure to blood, irrigation fluid and the related germs, viruses and diseases that are potentially found in the surgical environment. Today’s manual surgical fluid handling methods of hand-carrying filled surgical fluid canisters and emptying these canisters is an exposure risk and an antiquated approach to the handling of surgical fluid waste. BioDrain’s Streamway system fully automates the collection, measurement and disposal of surgical fluids resulting in: 1) reducing overhead costs to hospitals and surgical centers, 2) improving the Occupational State and Health Association (OSHA) and other regulatory compliance, and 3) improving the efficiency of the operating room (and thereby making surgeries more profitable).

BioDrain’s Streamway System is eco-friendly as it contributes to cleaning up the environment. Currently, approximately 50 million bloody, potentially disease-infected canisters go to landfills annually in the United States. These tainted canisters can remain in landfills for years to come. With the installation of BioDrain’s Streamway system, the number of canisters can be significantly reduced. BioDrain Medical, Inc. makes the operating room and our environment safer, cleaner, and better. BioDrain products are currently being represented by independent professional sales representatives that cater to the needs of hospitals and ambulatory surgical centers across the country.
