The customer reported that the or towels (b)(4)from the cardiac catheterization kit/ (b)(4) were shedding fibers onto the wires before entering the patient¿s body and in the rinse bowl.The procedure performed was a cardiac left heart catheterization with possibility of stenting.There was no injury or delay.No patient demographics were provided.Based on supplier investigation, the device history record could not be reviewed as a lot number was not provided.No sample was provided for evaluation, only a photo showing cotton lint to twine on the medical wire and rinsed on gloves.The supplier checked retained sample.The average linting data was 0.173g / 10 pieces and within limits (=0.38g/10 pieces).The or towel is made of cotton, so lint is born and inevitable.The intended use of or towel is to be used for applying medication to or absorbing small amounts of body fluids from a patient's body surface.Measures to better control and improve linting have been implemented.A suction process was added before products' final folding and operators perform this activity according to standard operation procedure requirements.In the folding process, one cloth bag protects 100 pieces of semi-finished products to avoid linting stuck onto the products during product transfer.Based on the investigation, all linting test data is within the acceptable range.There is no abnormal situation that has happened in production.Therefore, the root cause could not be determined and no further action.The complaint information was shared with the relevant sectors within the manufacturing facility for their awareness and we will continue to monitor for this type of incident.
