The aims of this study were to assess resistive heating of microwires used for remote catheter steering in interventional magnetic resonance imaging and to investigate the use of alumina to facilitate heat transfer to saline flowing in the catheter lumen.A microcoil was fabricated using a laser lathe onto polyimide-tipped or alumina-tipped endovascular catheters. In vitro testing was performed on...
The aim of this study was too assess magnetic resonance imaging (MRI) radiofrequency (RF)–related heating of conductive wire coils used in magnetically steerable endovascular catheters.A three-axis microcoil was fabricated onto a 1.8Fr catheter tip. In vitro testing was performed on a 1.5-T MRI system using an agarose gel–filled vessel phantom, a transmit-receive body RF coil, a steady-state free...
