Weill Cornell science briefs May 2008

l catheter is then guided up through the maze of the blood vessels of the circulatory system and into the targeted heart chamber. Then, a tiny metal clip is clamped into the area to stabilize the malfunctioning valve. This less-invasive method also means less morbidity and less recovery time as little as a one-day stay in the hospital compared to the usual five days.


Combating Stroke
Outfitting Device With Drugs to Prevent Future Stroke

Dr. Pierre Gobin is the inventor of the MERCI Retriever, a catheter corkscrew device that slips into the blood vessels of the brain to hook onto and then remove blood clots. But now, Dr. Gobin is working on another pioneering advancement: the combination of the MERCI device with a drug delivery system to protect the affected part of the brain as blockages are removed. Doing so might help to minimize damage to blood-starved brain tissue, while lowering the risks associated with removal of a blockage, such as reperfusion hemorrhage a form of bleeding caused by the weakening of blood vessels due to the absence of blood flow.

For the first time, Dr. Gobin and his team, in collaboration with faculty at Cornell Universitys School of Engineering in Ithaca, New York, have developed a novel microcatheter to successfully deliver neuroprotective drugs through the brain arteries of a rat. The compounds were infused both into an entire hemisphere of the brain, and into the basal ganglia, the deep brain structures that help start and control movement and which are often damaged by stroke.

Infection by Deadly Bacterium Can Be Prevented With Proper Sanitation

As urban sprawl spreads throughout the globe, so do poor urban ghettos and the infectious diseases that are perpetrated by unsanitary slum conditions. Weill Cornell researchers stationed in the urban slums of Salvador, Brazil, have discovered that certain unhealthy living conditions lead to transmi
