As reported, the yellow marker at the tip of catheter came off and embolised, lodging in cauda right atrium.A decision was made not to attempt retrieval as small and likely not to cause a problem.Later, there was some difficulty passing catheter through interstices of stent immediately prior to event; however, no significant force required to pass it and eventually went through easily with some torquing of catheter.There was no reported patient injury.The device will not be returned for analysis.

After further review of additional information received the following sections have been updated accordingly.During an unknown procedure, the yellow marker at the tip of a 4 french tempo catheter came off and embolized, lodging in the ¿cauda right atrium.¿ there was no reported patient injury.A decision was made not to attempt retrieval as its small size would likely not cause a problem.There was some difficulty passing the catheter through the interstices of stents immediately prior to event; however, no significant force was required to pass it and eventually it went through easily with some torqueing of the catheter.The device was not returned for analysis.A review of the manufacturing documentation associated with lot 17470606 was performed and no issues were noted that were related to the reported complaint.The reported ¿brite tip/distal tip-catheters separated - in-patient¿ and ¿catheter (body/shaft) tracking difficulty - in-patient¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.Vessel characteristics, while unknown, may have contributed to the reported event as high degrees of tortuosity and stenosis are known to cause damage to catheters.Handling factors may have also contributed to the event as catheters are delicate devices.According to the instructions for use, which is not intended as a mitigation ¿to prevent damage to the catheter tip during removal from the package, grasp the hub and withdraw the catheter.Exercise care when removing guidewires from multiple-curve catheters.Use a guidewire when introducing the catheter through the catheter sheath introducer (csi).Treat all 4f (1.35 mm) catheters and smaller french sizes with ultimate care.The performance of these products may be impaired if not properly and cautiously handled during unpacking and preparation.¿ neither the phr (product history report) review nor the product analysis suggests that the reported failures could be related to the manufacturing process of the unit.Therefore, no corrective or preventative actions will be taken at this time.
