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 lot history, applicable previous investigation(s), labeling, applicable manufacturing records, and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of a damaged safety mechanism is confirmed and appears to be caused by a bend in the needle shaft.One 22 ga x 0.75 in safestep infusion set was returned without product packaging.The safety mechanism was not advanced.Evidence of use was present within the extension tubing.A slight bend was observed.An attempt to advance the safety mechanism revealed excessive resistance.Additional force was applied in order to successfully activate the safety mechanism.A noticeable bend in the needle shaft was observed near the proximal end of the needle.Microscopic observation revealed no significant needle bevel deformation.The bend in the needle shaft was likely caused by force applied during insertion or use of the device.Since the bend was the source of the difficult safety mechanism activation, the complaint is confirmed and appears to be related to the use of the device.A lot history review (lhr) review is not possible, as no manufacturing lot number has been provided by the complainant.
