A Robotic System for Treating Intracranial Hemorrhage (ICH)


Vanderbilt researchers have designed a minimally-invasive, image-guided robotic system for delivering a steerable needle through the brain to a blood clot. Aspiration is provided through the steerable needle to remove the clot and decompress the brain. The system is no more invasive than a standard brain biopsy, and preliminary studies show that the system is successful at removing phantom clots via the steerable needle approach.

Addressed Need

The current surgical treatment for ICH often involves an invasive craniotomy in order to expose the blood clot, which causes unnecessary displacement of healthy brain tissue. The robotic steerable needle system is designed to cause disruption of a minimal amount of healthy brain tissue on the way to the clot, and once there, to remove the clot from within. 

Technology Description

The robotic system controls the actuation of two tubes that comprise the steerable needle. Control of the system is performed under image-guidance, providing feedback to the surgeon during removal of the clot. The sterilizable, biocompatible robot incorporates a suction system for decompression of the hemorrhage site.
