Event Description

It was reported that tip separation, unretrieved device fragment, additional intervention, and vascular perforation occurred.A coronarography was performed on a lesion in the intermediate stenosed right coronary artery (rca).Vascular access was obtained via the radial artery.A comet wire was advanced, and while navigating into the 2nd segment of the rca, the radiopaque segment fractured, which remained in the vessel.It was noted that while progressing in the rca to reach the lesion intended for evaluation, the radiopaque segment of the comet wire was observed to be fractured and separated from the wire.The separation occurred 3cm from the tip.A new angiography was performed and there was an attempt to withdraw the fractured segment during the second procedure but failed and resulted with a vascular perforation.It was noted that the tip of the guide/diagnostic catheter maintained position in the ostium during the entire procedure.It was later reported that no other devices were tracked over the wire and that the comet wire fractured when navigating down the artery, there was no abnormality in the patient's anatomy, and the tip did not become trapped at any point during the procedure.The procedure was not completed successfully.No additional patient complications were reported in relation to this event.

Manufacturer Narrative

Device returned to manufacturer: the devices shaft was visually and microscopically inspected for damage.The device showed multiple kinks and bends throughout the wire shaft.The tip was separated from the shaft at 3cm.The separation was not on the laser cut part of the shaft.The coefficient was confirmed to be programmed per specification.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The complaint of device tip detachment was confirmed.Device analysis determined the condition of the returned device was consistent with the reported information.
