MITT - Minimally Invasive Transcranial Thrombectomy


To test a catheter that removes intracranial blood clots from stroke patients

Anticipated Impact: 

Reduced 30-day mortality rates, intensive care unit (ICU) days, and long-term care intensity in patients suffering from hemorrhagic stroke


Hemorrhagic stroke affected more than 2,000 Washingtonians last year. Half of all victims die within one month; most survivors require support for the remainder of their lives. In 2010, the direct cost of hemorrhagic stroke in Washington was $274 million ($12.7 billion in the US). Recent preclinical and clinical evidence supports evacuation of stroke-related blood clots through minimally invasive surgery to improve patient outcomes. Viket has designed a catheter that is compatible with familiar neuronavigation imaging equipment and that can be used to remove clots in minutes. The tip includes an ultrasound proximity sensor to help surgeons avoid healthy brain tissue. Through LSDF funding, Viket has tested its second-generation catheter design in a human skull model and an animal model. A supplement was awarded to add 3-D visualization of the clot. This modification is expected to simplify use by the neurosurgeon and increase the catheter’s commercial appeal.

Grant Period:
09/19/2012 - 09/18/2013 (Completed)
Grant Amount:
With our LSDF grant we were able to demonstrate that a 3 dimensional representation could be created with the Viket imaging tip. This elegant proof of concept may provide important evidence that will drive investors to financing Viket's next round.
