The disposable infinity sampling device is intended to be sued to retrieve cytological cell samples in the gastrointestinal tract.A distributor reported the device brush head detached and was retained above stenosis while sampling in the lower biliary duct.The patient was not harmed by the retained brush head.A stent was placed to reduce the stenosis.The physician determined the brush head would be retrieved after expansion of the stent, in a later procedure.In follow up communications, the distributor reported the brush head was retrieved in a second procedure, with no harm to the patient as a result of the retained brush head and no harm due to the retrieval.Examination of the returned device found evidence of bending at the distal catheter.Examination of the returned brush head found similar evidence of bending on the wire stem of the brush head.The instructions for use warn against forcing the device through the endoscope channel and instructs to reduce elevator angulation if resistance is met.This report will be updated if additional information becomes available.
