NSF Webcast: Getting a Grip on Stroke Treatment
Wed, 19 May 2010 16:42:00 -0500

Modeled environment for testing the Insera blood-clot removal device.

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 ...
