H11: section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.The following were reviewed as part of this investigation: patient severity, complaint and batch history, applicable previous investigation(s), labeling, applicable manufacturing records, sample analysis and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint that the needle detached from the infusion set was confirmed but the cause is unknown.The products returned for evaluation were one 1¿ detached needled from an infusion set, 12 unopened 20g x 1¿ bard winged infusion sets labeled ref (b)(4) and lot redw2506, and 5 unopened 20g x 1¿ bard winged infusion sets labeled ref (b)(4) and lot redx1470.Examination of the infusion sets from the unopened kits revealed that the needles were securely adhered within the needle housings.The samples were patent to infusion and no leaks were detected when the samples were hydraulically pressurized.The needles did not become loose or detach when accessing and deaccessing a non-complainant port.No defects or deformities were noted on the unopened infusion set samples.The detached needle was returned without the interfacing infusion set.The needle shaft, proximal to the manufactured bend was bent.The needle bevel was severely deformed with the bevel tip curling under itself and to the side.A small amount of white residual material was seen along the edge of the needle bevel.Microscopic examination of the needle, proximal of the manufactured bend, revealed a clear material around the needle which appeared to be the manufacturing adhesive.Small voids were seen in the adhesive.The voids were parallel to each other and evenly spaced.It appears that the voids in the adhesive were caused by mechanical tools grasping the needle, possibly while removing the needle from the patient.If the needle bevel was damaged prior to infusion set removal, the damage could have contributed to a difficult removal.Difficult infusion set removal may have contributed to the event of needle detachment.However, it cannot be determined from examination of the needle what damage was due to use and what damage occurred during the removal and later shipping of the needle.Other potential contributing factors could include stress on the bond between the needle and wings due to forceful advancement of the needle against the port, complications with needle insertion/removal, and/or manipulation of the inserted infusion set during use.A review of the manufacturing documents for this batch/lot was conducted.No deviations or issues were identified that were associated with the reported event regarding product materials, manufacturing, packaging, or the inspection process.All necessary inspections were performed throughout the manufacturing and packaging of this lot/batch.H3 other text : evaluation findings are in section h.11.
