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 difficulty assembling the catheter/connector system was confirmed.The product returned for evaluation was one 4fr s/l groshong connector.The sample comprised the distal segment.The proximal segment was not returned for evaluation.A segment of catheter shaft was visible within the clear strain-relief sleeve.Following longitudinal bisection of the sample, inspection of the compression sleeve revealed that it contained a fragment of catheter shaft and had been advanced nearly entirely into the narrow region of the bore.Microscopic inspection compression sleeve confirmed that it was advanced too far into the narrow region of the bore.The catheter fragment was compressed and folded within the sleeve.Mechanical damage was observed at the proximal region of the sleeve.The end of the catheter was roughly aligned with the compression sleeve.The catheter alignment indicated that the catheter had not been fully inserted through the distal connector segment during catheter/connector assembly.The catheter was compressed and folded within the compression sleeve because the compression sleeve had been too far advanced into the narrow region of the connector bore.The mechanical damage suggested that connector cannula may have caught on the compression sleeve, causing it to be inserted too far into the distal connector segment.Such damage may be avoided if the catheter is passed entirely through the distal connector segment and advanced over the metal cannula prior to connector assembly.H3 other text : evaluation findings are in section h.11.
