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 review, applicable previous investigation(s), sample (if available), labeling, and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of a broken guidewire is confirmed.One accucath device was returned for evaluation.An initial visual observation showed the device was returned without a catheter, and the safety mechanism of the device was observed to have been activated but the needle tip remained protruding from the distal end of the housing.The guidewire was observed protruding from the flash groove of the needle when the needle was advanced, and the guidewire was found to be broken.A microscopic observation revealed the break site of the guidewire was tapered and curved with a granular surface texture, which is characteristic of a tensile (pulling) failure.Advancement of the guidewire against resistance (such as against tissue) can cause the guidewire to become caught in the flash groove of the needle.The shape and texture of the break in the guidewire of the returned device suggest the guidewire was also retracted against resistance, which ultimately caused the guidewire to break.The product ifu warns: ¿do not force or retract the guidewire.Retracting the guidewire may increase the risk of guidewire damage.If the guidewire must be retracted, remove the entire device to prevent the needle from damaging or shearing the guidewire.¿ h3 other text : evaluation findings are in section h.11.
