Background: Mechanical thrombectomy can restore blood flow to the brain after acute ischemic stroke, but may be associated with risks, such as breakage of moving parts and clot fragmentation. The aim of this study was to evaluate a new aspiration thrombus device (ATD), the GP ATD, which has no moving parts and extracts clots by suction in a vortex flow pattern.
Methods: The GP ATD is used to extract porcine blood clots inserted into the middle cerebral artery (MCA) of a model of the circle of Willis, and from porcine aorta.
We present data concerning the extraction of clots using the newly invented "GP" mechanical thrombectomy device (MTD). Artificial and porcine clots of various lengths were used in plastic tube models of an artery. We investigate the pressures and times taken for clot extraction together with the volumes of fluid extracted.
