Manufacturing review: a lot history review, a device history record review, and complete manufacturing review could not be conducted for the investigation as the lot number is unknown.Investigation summary: one powerport mri isp attached to a groshong catheter were returned for evaluation.Visual, microscopic and functional evaluation were performed on the returned device.Two circumferential kinks were noted on the catheter approximately 7.6cm and 8.4cm from the distal end of the cath-lock.A partial circumferential break was noted approximately 9.0cm from the distal end of the cath-lock.The edges of the partial circumferential break were jagged with smoothed and rounded surface.The observed characteristics are consistent with damage due to flexural fatigue.The breaking with smoothed and rounded edges are characteristic of flexural fatigue, which is due to the repetitive kinking of the catheter.Further during functional evaluation both the port body and catheter segment were patent to infusion with a leak noted at the site of break.Aspiration was attempted, but was unsuccessful.Therefore, the investigation is confirmed for aspiration problem, fracture, deformation and leak.A definitive root cause could not be determined based upon available information.Labeling review: a review of product labeling documentation (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.(device: 1250) 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.
