The reported event was unconfirmed since the problem could not be reproduced.The evaluation found that the returned catheter could function as intended.No abnormalities or defects were observed on the catheter.The catheter was dissected and no damage or breakage was observed on the thermistor wire that could potentially result in display failure.Therefore, the reported event is unconfirmed based on the investigation findings.The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The instructions for use were found adequate and state the following: ¿1) based on non-clinical studies, mri safety for the device is confirmed under the following conditions: static magnetic field of 3-tesla or less with regard to magnetic field interactions.Spatial gradient magnetic field of 720-gauss/cm or less with regard to magnetic field interactions.Maximum mr system reported whole-body-averaged specific absorption rate (sar) of 3.5-w/kg at 1.5- or 3-w/kg at 3-tesla for 15 minutes of scanning.2) the position of the wire of the foley catheter with temperature sensor has an effect on the amount of heating that may develop during an mri procedure.Accordingly, the foley catheter with temperature sensor must be positioned in a straight configuration down the center of the patient table (i.E., down the center of the mr system without any loop) to prevent possible excessive heating associated with an mri procedure.3) importantly, the mri procedure should be performed using an mr system operating at a static magnetic field strength of 1.5-tesla or 3-tesla only.The safe use of an mr system operating at lower or higher field strength for a patient with a foley catheter with temperature sensor has not been determined.4) if the foley catheter with temperature sensor has a removable extension cable, it should be disconnected prior to the mri procedure.5) remove all electrically conductive material from the bore of the mr system that is not required for the procedure (i.E., unused surface coils, cables, etc.).6) keep electrically conductive material that must remain in the bore of the mr system from directly contacting the patient by placing thermal and/or electrical insulation including air between the conductive material and the patient." h11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
