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. We also investigate the impact of(More)
Auditory brainstem responses to clicks in quiet, notch noise, and highpass noise were recorded from 10 normal-hearing adults. Contrary to some reports, the latency of wave V increased as the center frequency of the notch decreased. Response identifiability and wave V amplitudes were similar for the notch and highpass noises. Thus, the additional frequencies(More)
BACKGROUND AND PURPOSE Venous malformations are the most common of all vascular anomalies, 40% of which are found in the head and neck. We discuss results of percutaneous sclerotherapy using bleomycin for facial VMs by using subjective clinical assessment and objective changes on MR imaging. MATERIALS AND METHODS Thirty-seven patients with facial VMs were(More)
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(More)
We present 3-D FLUENT simulation modelling of the GP’ Mechanical Thrombectomy Device (MTD) used with a modified funnel structure. Comparisons are made of the results obtained from this modelling with actual measurements made in an in-vitro model of the ‘GP’ MTD with an end mounted funnel structure used in experiments. There was good(More)
