H10: manufacturing review: a manufacturing review was not requested as the lot number reported is unknown.Investigation summary: one powerport implantable port attached to a groshong catheter in two segments were returned for evaluation.Functional, gross visual, tactile, and microscopic visual evaluations were performed.The investigation is confirmed for the reported catheter fracture and the identified material separation, wear and deformation issues, as complete circumferential breaks were noted to the distal end of the attached catheter and proximal end of the distal catheter segment.The surface of the complete circumferential break on the distal end of the attached catheter were noted to be round and granular.The surface of the complete circumferential break on the proximal end of the distal catheter segment were noted to be granular and round.However, the investigation is inconclusive for the reported difficult to flush and suction issue, as the exact circumstances at the time of the reported event cannot be verified, and the reported event could not be reproduced in the lab.The identified break is typical of flexural fatigue, which is due to the repetitive, cyclic kinking of the catheter.The definitive root cause could not be determined based upon available information.Labeling review: a review of product labeling documents (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, and unit label) showed that the product labeling is adequate.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.
