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, trend analysis, applicable previous investigation(s), sample (if available), and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of guidewire difficulty was confirmed.The product returned for evaluation was one 20ga powerglide pro midline catheter assembly.Usage residues were observed throughout the sample.The catheter had been advanced and was not returned for evaluation.The safety mechanism was engaged over the needle tip.The guidewire was fully extended, but was not engaged with the guidewire advancer.The guidewire was bent at the exit site from the needle tip.The guidewire did not move during manipulation of the advancer because of that disengagement.Following disassembly, microscopic inspection of the guidewire advancer revealed wear marks in the coupler region.Both the wear marks on the coupler and the advanced position of the guidewire suggested that the guidewire was initially assembled correctly with the advancer and became subsequently dislodged.Such dislodgement can occur if guidewire advancement is attempted against resistance, such as into tissue.The blood residue suggested that dislodgement likely occurred during attempted device placement.H3 other text : evaluation findings are in section h.11.
