Manufacturer Narrative

Right ovarian vein was being embolized using an imp-10 device.The physician was using a 7fr apt medical guide catheter to deliver the imp-10.During device deployment, the imp-10 anchor coil formed in a straight configuration, instead of a helical shape.Because of this, the physician chose to remove the catheter containing the device.After removing the catheter from the patient, the physician ran a guidewire through the catheter lumen and the delivery introducer containing the imp-10 device emerged from the catheter.Subsequent attempts to advance the device were unsuccessful.Thereafter the case was completed using other embolic devices.No adverse event to the patient was reported.A review of the lot history record and lot release report identified no quality issues related to device performance.A benchtop investigation did not occurr because no device was returned to shape memory medical.Based on smm's review of the information received, the most probable root cause for this event is being attributed to the physicians use of the imp-10 device in spite of the fact that the temperature indicator label located on the device pouch had activated.The impede ifu states that if the temperature indicator label shows the temperature has been exceeded (i.E.The indicator dot is black), the device should not be used as the plug component of the device may have expanded impacting delivery performance.This abnormal use coupled with the physician having difficulty advancing the device through the introducer likely led to luer hub detaching from the introducer tubing and the anchor coil remaining straight and not forming a coil as expected.Smm complaint reference number: (b)(4).
