Olympus medical systems corporation (omsc) was informed that during an endoscopic stone removal using the subject device, the following event occurred.The subject device could not be removed from the patient since the device broke.The user tried to remove the device with the emergency lithotriptor.However, the wire of the device broke.The emergency lithotriptor was no longer usable since the wire became shorter.The wire was protruded from the patient's nose for the time being.On the next day, the user took place a follow-up endoscopic retrograde cholangiopancreatography (ercp), used eswl to crush the stone, and could remove the device from the patient.There is no deterioration of the patient's health condition.

Manufacturer Narrative

This is a supplemental report to provide additional information.The subject device was returned to olympus medical systems corp.(omsc) for evaluation.The operating wire was ruptured at 90 cm from the distal end of the basket.The full length of the operating wire presented no abnormalities, and no missing areas were observed.The operating pipe was ruptured.The tube sheath and operating portion were not returned for investigation.Upon analyzing the ruptured area of the operating wire, it was discovered that the shape of the revealed that a tensile force might have been applied to the ruptured area.The outer diameter of the operating wire was measured.The result indicated no abnormalities.The operating pipe was bent.Upon analyzing the ruptured portion of the operating pipe, it was discovered that the shape of the pipe revealed it has been crushed by something like a tool.The basket was crushed.The guidewire tip (distal tip) was not broken.The manufacturing record was reviewed and found no irregularities.Due to various factors such as the shape, numbers, hardness of the calculus, and the magnitude of the force necessary to close the basket, it can be inferred that a force larger than expected might have been applied to the device while the basket was grasping the calculus.As a result, the operating wire possibly ruptured.As a result of investigating the subject device, the exact location where the operating wire was originally ruptured could not be determined.In order to withdraw the tube sheath to combine with the emergency lithotriptor, the operating pipe might have been severed by using a tool.The above device handling has warned in the instruction manual as follows.*repetition of calculus retrieval will deform and/or deteriorate this instrument.Deformation and/or deterioration may make it difficult to retrieve a calculus or could cause the basket with calculus engaged to become impacted in the body.If calculus retrieval needs to be repeated in a single case, be sure to inspect the action and the appearance before each retrieval.Stop use if any abnormality (e.G., basket wire is cut or worn, tube sheath is bent, etc.) is detected during the inspection.
