BACKGROUND The rheolytic thrombectomy catheter has been specially designed to remove intravascular thrombus from coronary and peripheral arteries. It demonstrates a practical application of Bernoulli's principle relating to a low-pressure zone in the region of a high-velocity jet. In this device, this effect is created by direct high-pressure saline jets(More)
Technical advancement and new anti-thrombotic regimens have recently shown so much improvement in the results of coronary stenting that the conventional contra-indication for stenting in small coronary arteries (<3 mm) needs to be revised. We undertook a prospective pilot study of elective Palmaz-Schatz stenting in de novo lesions located in coronary(More)
OBJECTIVES The purpose of this prospective study was to evaluate the immediate results and the 6-month angiographic recurrent restenosis rate after balloon angioplasty for in-stent restenosis. BACKGROUND Despite excellent immediate and mid-term results, 20% to 30% of patients with coronary stent implantation will present an angiographic restenosis and may(More)
— We consider decentralized control of a process with multiple sensors, controllers and actuators interconnected by analog erasure links. To stabilize the process, feedback information needs to be transmitted over both implicit signaling channels and external erasure channels. Based on a data flow network model, a necessary and sufficient condition for mean(More)
This paper proposes a reconfigurable parallel architecture for space-borne on-board processing that combines the advantages of powerful computational resources with a straightforward software development. This approach introduces the concept of software payloads that enable the users the direct transfer of their ground-based applications towards space and(More)
Accurate segmentation of ventricular cerebrospinal fluid (CSF) regions in stroke CT images is important in assessing stroke patients. Manual segmentation is subjective, time consuming and error prone. There are currently no methods dedicated to extracting ventricular CSF regions in stroke CT images. 102 ischemic stroke CT scans (slice thickness between 3(More)
Consensus clustering, also known as clustering ensembles is a technique that combines multiple clustering solutions to obtain stable, accurate and novel results. Over the last years several consensus clustering approaches were proposed addressing practical clustering problems with different degrees of success. In this paper, we consider data fragments as(More)
