A new surgical device--tested using silicone copies of human cadaver blood vessels--is poised to advance stroke treatment and revolutionize how the medical community evaluates new technologies.

On Thursday, May 27, at 2:00 p.m. EDT, during a webcast hosted by the National Science Foundation, the developers of the net-like Insera SHELTERTM device will demonstrate how their technology filters and removes blood clots, and present the latest results from recent performance tests.

Interventional neurologist Vallabh Janardhan and Insera engineer and CEO Vikram Janardhan will explain how SHELTERTM (which stands for Stroke Help using an Endo-Luminal Transcatheter Embolus Retrieval device) may be a safer alternative to the common "corkscrew" approach for strokes, which can release stroke-inducing debris. The researchers will also describe their uniquely accurate testing platform, one nearly identical to living human tissues--complete with aneurisms, atherosclerosis and "plaque"--which may supplant certain types of animal testing experiments.

Who:Interventional neurologist Vallabh Janardhan and engineer Vikram Janardhan of Insera Therapeutics of Sacramento, Calif.

What:Webcast demonstration of NSF Small Business Innovation Research (SBIR)-supported Insera SHELTERTM device.

When:Thursday, May 27, 2010, at 2:00 p.m. EDT

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2022 budget of $8.8 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
