Manufacturer Narrative
Patient's exact age is unknown; however it was reported that the patient was over the age of 18. The device has been received for analysis; however the evaluation has not been completed. Therefore, the cause of the reported malfunction has not been determined. Upon completion of the failure analysis of the complaint device, if there is any further relevant information from that review, a supplemental medwatch will be filed.
 
Event Description
It was reported to boston scientific corporation that a lithovue standard deflection scope was used in the kidney during a nephroscopy procedure performed on (b)(6) 2018. According to the complainant, during procedure, a foreign object that looks like a ¿jelly roll¿ was lodged in the patient and was seen by the physician inside the working channel of the scope. Reportedly, the object does not look like a part of any device. The foreign object was retrieved upon withdrawal of the lithovue scope however it was not retained. A different device was used to complete the procedure. There were no patient complications reported as a result of this event. The patient condition at the conclusion of the procedure was reported to be stable. Additionally, the patient had previous surgical procedures. Last (b)(6) 2018, the patient had nephrostomy with stent insertion due to 10 mm stone. On (b)(6) 2018, the patient had a left sided rigid ureteroscopy with disintegration and extraction of stone fragments and the recent procedure on (b)(6) 2018 for a ureteroscopy to extract 4 mm stone fragment from lower renal calyx.
 
Manufacturer Narrative
Additional information received on 02jul2018. A lithovue single-use digital flexible ureteroscope was returned for evaluation. Visual examination revealed that the black covering of the active deflection section appeared to have fallen off. Additional examination on the black covering revealed that the composition does not match with the foreign matter reported by the customer which was "diaphanous" and ¿jelly roll¿. There was no foreign material found inside or pushed out of the working channel upon disinfection. It is likely that the foreign matter reported by the customer was a component from the inner lumen of the navigator hd access sheath used by the customer without lubricant. It is also likely that matter emerging through the access sheath, such as a component of the access sheath that rubbed off would appear like matter emerging through the working channel, as described by the customer. Based on all gathered information, the noted damages indicate difficulty was experienced during the procedure and are likely due to anatomical or procedural factors such as tortuous anatomy or maneuvering of the device. Therefore, a review and analysis of all available information indicated that the most probable root cause is operational context. A review of the device history record (dhr) was performed; no anomalies were noted. A search of the complaint database revealed that no similar complaints exist for the specified lot. A labeling review was performed, and from the information available this device was used per the directions for use (dfu)/product label.
