Per the creation of (b)(4), the contact reported finding foreign matter (reported as yellow liquid) on the product inside the sterilized package.A 2nd complaint with the same description was created per (b)(4).Seven products were returned with four of them being unopened (for (b)(4)).The product code is 20-1038 (disposable scalp clip applier).The lot code provided was 363631.Upon completion of the investigation, the operators were retrained to mps-pc509.Internal operations were reviewed for the assembling of disposable scalp clip appliers.Per mps-pc509 rev u, the use of an oil lubricant is permitted.For lot code 363631, a yellow spot was seen on the tyvek lid and on the tip of the clip applier.In disassembling one of the returned and opened components, an oil track (or drip line) was observed.It was concluded the fluid is the oil lubricant.A procedure exists for the lubrication of the clip sleeve (refer to mps-pc509 rev u).Manual operation includes placing three drops of oil in the indicated area.The root cause can most likely be attributed to human error as the lubrication process is a manual operation.Upon disassembling one of the returned products, a trail of oil was found along the entire length of the device, originating from the clip sleeve.An excessive amount of oil was added to the product and ultimately contributed to the runoff of oil.The production records for this lot were reviewed and no non-conformances were found.Trends will be monitored for this and similar complaints.At the present time, this complaint is considered closed.
