Event Description

As reported to customer relations via phone conversation "the device went inside the patient and the stent was deployed.But when the physician was taking out the deployment system, the distal tip became detached from the system.The white distal tip remained inside the patient.However, the physician was able to remove the white distal tip as the tip was still attached to the wire.The whole system was removed together, thereby removing everything from the patient." summary of what happened: the delivery system had some resistance while loading it onto the wire, however i think the wire was not properly lubricated (i was busy making sure the tech was flushing the system correctly).We flushed the system again and wiped the wire down generously and it loaded onto the wire with no resistance.After the stent was deployed successfully, the physician and i noticed the distal white tip on the delivery system was missing , while pin and pulling the delivery system out of the patient.The doctor basically tore apart the delivery catheter to make sure it was not in there.Then he was able to pull the sheath out with the wire still in patient and luckily the white tip was on the wire.We were able to successfully remove it.Patient outcome: did any unintended section of the device remain inside the patient¿s body? - no · please describe the object and how it was retrieved: did the patient experience a delay or require any additional procedure due to this occurrence? - no · please specify delay or any additional procedure(s) and provide details: has the complainant reported any adverse effects on the patient due to this occurrence? - no has the complainant reported that the product caused or contributed to the adverse effects? - no · please specify adverse effects and provide details.
