During testing, the SHELTER device grabs a simulated blood clot (a moistened gummi bear) from within a silicone "blood vessel." The water-filled, silicone test-bed was modeled from human-cadaver brain vessels, and contains added aneurysms, atherosclerosis and "plaque" to provide the device an even more challenging testing environment. The new test-bed is more accurate than certain animal tests, and has helped speed the device's development. Potentially, the test-bed could present a new approach to late-stage evaluation of certain medical technologies.
