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), applicable manufacture records, and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of inter-luminal communication is confirmed and was determined to be manufacturing related.One 5 fr dual lumen powerpicc was returned for evaluation.Both lumens of the returned sample were flushed and pressurized with a 12 ml syringe of water and, once the needleless injection caps were removed, water was found to exit from the hub of the red lumen when the purple lumen was infused, indicating communication between the two lumens.The catheter was clamped at multiple locations along its length and the inter-luminal communication was determined to be within the bifurcation of the catheter.The catheter was cut near the center of the bifurcation and dissected.A microscopic observation revealed a longitudinal split in the septum of the catheter lumens, just distal to the junction of the extension leg tubing and the catheter lumens.This split was observed to be straight with slightly rough edges.The fracture surfaces of the split were observed to be flat and granular in texture.The location of this split indicates the damage likely occurred during manufacturing.The investigation was forwarded to the manufacturing facility for further evaluation.Reynosa evaluation: complaint due to ¿hole between the two lumens¿ was confirmed.According with the photo evaluation performed at reynosa facility and gross visual, microscopic visual, and functional testing performed at vad lab the following was concluded: a longitudinal split was found to be within the bifurcation area causing inter-luminal communication between both lumens.This condition was caused during the over-molding process and makes the device unusable for patient¿s treatment.Therefore, the cause of this condition is manufacturing related.A lot history review (lhr) of redt3514 showed no other similar product complaint(s) from this lot number.
