Tailored magnetoelastic sensor geometry for wireless biliary stent monitoring
This paper presents three types of wireless magnetoelastic resonant sensors with specific functionalities for monitoring sludge accumulation within biliary stents. The first design uses a geometry with a repeated cell shape that provides two well-separated resonant mode shapes and associated frequencies to permit spatial localization of mass loading. The second design implements a pattern with ...
متن کاملIn situ and ex vivo evaluation of a wireless magnetoelastic biliary stent monitoring system.
This paper presents the in situ and ex vivo evaluation of a system that wirelessly monitors the accumulation of intimal tissue and sludge in a biliary stent. The sensing element, located within the stent, is a magnetoelastic resonator that is queried by a wireless radio frequency signal. The in situ testing uses a commercially-available self-expanding biliary stent enhanced with a 1 mm x 25 mm ...

متن کاملIn vivo and in situ evaluation of a wireless magnetoelastic sensor array for plastic biliary stent monitoring.
This paper presents the in vivo and in situ evaluation of a system that wirelessly monitors the accumulation of biliary sludge in a plastic biliary stent. The sensing element, located within the stent, is a passive array of magnetoelastic resonators that is queried by a wireless electromagnetic signal. The in vivo and in situ testing uses commercially-available plastic biliary stents, each enha...
متن کامل[Cost-effectiveness trial of self-expandable metal stents and plastic biliary stents in malignant biliary obstruction].
INTRODUCTION Self-expandable metal and plastic stents can be applied in the palliative endoscopic treatment of patients with unresectable malignant biliary obstruction. The use of metal stentsis recommended if the patient's life expectancy is more than four months. AIM To compare the therapeutic efficacy and cost-effectiveness of metal and plastic stents in the treatment of malignant biliary ...
