A team of researchers has developed an artificial lung that uses regular air, not pure oxygen, and is portable, marking a huge step forward for people with acute and chronic lung disease. The research is a result of collaboration between CWRU and the Louis Stokes Cleveland VA Medical Center.
"The most significant finding is that we have demonstrated a small scale, prototype artificial lung," says Joseph A. Potkay, research assistant professor in CWRU's department of electrical engineering and computer science. "It represents a major leap forward toward a self-contained, portable or implantable device that would use ambient air, rather than oxygen cylinders, and would thus give patients full mobility."
Current artificial lung systems require heavy tanks of oxygen, limiting patients' portability -- and they can be used only on patients at rest. Also, the lifetime of the system is measured in days. This new prototype is much smaller in size -- equivalent to a natural lung.
"These results prove that constructing a device with features similar in size to those found in the natural lung can result in large improvements in efficiency over current alternatives, thereby enabling portable devices," says Potkay. "This technology will be used in portable heart lung machines and portable systems for the treatment of acute and chronic lung disease or as a bridge to transplant."
Potkay and his team began developing the lung in early 2008 and will begin animal testing in two years. Human trials should begin in 10 years. The research was funded by the U.S. Department of Veterans Affairs. Lung disease affects over 200 million people worldwide.

From University Circle to Slavic Village to Buckeye and beyond, art abounds in and around Cleveland. In this pictorial essay, Fresh Water photographer Bob Perkoski trains his lens on the stunning, stirring and thought-provoking works that can be found inside Cleveland's finest repositories of art to some of Cleveland's most overlooked urban enclaves. Art, both classical and modern, architecture and design fill this city with beauty, imbue its citizens with hope, and brighten up the places we live, work and play.
Recent CWRU mechanical engineering graduates Austin Schmidt and Solomon Alkhasov won the 2011 Idea Competition, sponsored by LaunchHouse and CSU's Accelerated MBA program at Nance College of Business. They created a company called Affinity Algorithms, which develops proprietary computer arbitrage software to facilitate transactions between buyers and sellers in various online marketplaces. The software provides greater liquidity and price transparency in the marketplaces.
"We are developing a suite of online software that helps the seller in fragmented marketplaces better manage inventory," explains Schmidt. Although Schmidt and Alkhasov came up with the idea from their experiences buying and selling textbooks in college, they say it can be applied to many online marketplaces.
The idea for Affinity Algorithms came about in January, they set up shop in March, and landed at LaunchHouse this month. They plan to roll out a full build of the software in September.
Students from all Northeast Ohio colleges and universities were invited to pitch a business concept to a panel of entrepreneurs, venture capitalists, CSU faculty and LaunchHouse staff. The contest primarily focused on students who had innovative ideas in the fields of software and internet technology, low-tech medical devices and clean energy.
The second winner is Ronny Shalev, also a student at Case. Shalev created a product known as an autonomous intravenous (IV) insertion tool that will be the most effective replacement for the current procedure of manual vein localization and needle insertion. Shalev's tool will completely replace the need for trained medical staff.
Contest winners were each awarded a $2,500 scholarship to the Global AMBA program along with a prize basket of support services from LaunchHouse, "Additionally, we received a $500 check from LaunchHouse, along with a bunch of services that include legal services, accounting, and free space for three months," says Schmidt. "All in all, a very comprehensive package with everything needed to get a business off the ground."
The winners will also have the opportunity to compete for up to $5000 in follow on funding.

The PNC SmartHome is complete at the Cleveland Museum of Natural History and open to visitors who want to learn how to make environmentally-friendly improvements to their own properties. The 2,500-square-foot three-bedroom house uses 90 percent less energy than a traditional home, and it uses no furnace for heating and cooling. The walls are a foot thick and packed with insulation, while the windows are triple-pane glass -- both of which reduce heat loss. The home is heated and cooled with small heat pumps.
"The museum wanted to help people understand how they can dramatically reduce energy consumption," says David Beach, director of the GreenCityBlueLake Institute at CMNH. "We think the SmartHome will be the first home to receive passive home certification in Northeast Ohio."
Other features include hardwood floors made from 100-year-old reclaimed wood and artwork with environmental themes created by local artists. The landscaping features storm water management techniques to keep rain water on-site instead of in storm sewers.
So far, the home has been well-received. "People walk in it and go, 'wow,'" says Beach. "What they are reacting to immediately is what a beautiful home it is. Then they see they can learn things [to do] for their own homes."
The house will be moved to an empty lot on Wade Park Boulevard this fall and will go on the market soon. Beach says they've already received inquiries about purchasing the house.
Tours run Monday through Saturday 11 a.m. to 4 p.m., Wednesdays from 11 a.m. to 9 p.m. and Sundays 12:30 p.m. to 4 p.m. Tickets are $5 with museum admission, $3 for those who can't go upstairs. Children 2 and under are free.
