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.Based on a review of applicable information, the following was concluded: the complaint of damaged extension tubing is confirmed; however, the root cause could not be determined.The product returned for evaluation was a 20 cm niagara slimcath acute dialysis catheter.Use residue was visible throughout the device.There was a complete break in the arterial lumen extension tubing.A circumferential aligned split was observed in the venous extension tubing.Microscopic inspection of both the complete break and partial split revealed granular fracture surfaces.Superficial stress fractures were observed in the vicinity of both the break and the split.Additionally, the extension tubes exhibited elliptical cross sections at the break and split sites.The shapes of the extension tubes near the break/split sites suggested that compression force, such as that applied by the clamps, contributed; however, the stress fractures suggested that an additional unidentified factor(s) also contributed.This complaint will be recorded for future trending and monitoring purposes.H3 other text : evaluation findings are in section h.11.
