Manufacturer Narrative

This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.A review of the device history record found no deviations that could have caused or contributed to the reported issue.Based on the results of the investigation, since the device was not returned for evaluation, the root cause could not be determined.However, based on past investigation results, it is likely that during the emergency lithotripsy (with the cook emergency handle), various factors such as the size, hardness or shape of the calculus, a load beyond the resistance strength, etc., may have applied to the product.As a result, the operation wire was broken (tore off), and the basket fell off inside the patient.Also, due to various factors such as the size, hardness or shape of the calculus, the basket could not be retracted.The event can be detected/prevented by following the instructions for use (ifu) which state: ¿before use, thoroughly review the instruction manuals for this instrument and the lithotripter (bml-110a-1) to determine the proper method of use.Using the instrument and lithotriptor without thoroughly reviewing their manuals could cause patient injury.¿do not use this instrument if the target calculus is found to be impossible to retrieve through preoperative diagnosis, interoperative contrast enhancing, or after papillotomy/papillary dilation.Do not use this instrument to grasp multiple calculi at one time.Doing so may make it impossible to remove the basket (with calculi engaged) from the patient.Use this instrument with a hospitalization plan ready and the understanding that, if the calculus is too hard to be crushed by the lithotriptor (bml-110a-1), the instrument may become irreversibly damaged and open surgery may have to take place in order to remove the calculus." "when using the bml-110a-1 mechanical lithotriptor, there is a possibility that the basket could become damaged as shown in section10.8, ¿emergency treatment¿.Use the bml-110a-1 with the understanding that the basket could become damaged and open surgery may have to be performed.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." "when using the bml-110a-1, do not withdraw the tube of this instrument from the endoscope while the endoscope is inserted into the patient body.If the endoscope is withdrawn from the patient body, after the tube of this instrument is withdrawn from the endoscope which is still in the patient body, (i.E., if the endoscope is withdrawn from the patient body while the only operation wire of this instrument is still in the endoscope), the forceps elevator of the endoscope contacts the operation wire of this instrument during the withdrawal of the endoscope and may kink the wire.The kink of the operation wire may make it impossible that the distal end of the coil sheath of the bml-110a-1 is inserted into the patient body over the operation wire till the distal end reaches the target calculus and enable the bml-110a-1 to function.When using the bml-110a-1, either withdraw the tube together with the endoscope from the patient body or withdraw the tube of this instrument from the patient body after withdrawing the endoscope from the patient body.Then, insert the coil sheath of bml-110a-1 into the patient body over the operation wire of this instrument.¿ olympus will continue to monitor field performance for this device.
