The information provided by bard 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 bard.The following were reviewed as part of this investigation: patient severity, trend analysis, applicable previous investigation(s), sample (if available), applicable fmea documents, labeling, and applicable manufacture records.Based on a review of this information, the following was concluded: the complaint was confirmed and the cause is use related.The product returned for evaluation was a 5fr single-lumen 45cm power groshong catheter.The investigation findings are consistent with damage accumulated through flexural fatigue.Flexural fatigue occurs due to cyclic kinking of the catheter tube in which physiological, placement, usage, and mechanical factors may gradually form a crack(s) in the catheter.The catheter split was located between the 40cm and 41cm depth markings, and the observed damage which is characteristic of this failure type included: circumferentially aligned split in the catheter, rounded fracture edges, impressions from material buckling near the fracture site, and polished features due to material wear.An examination of the catheter structure revealed no potential damage/defect related to manufacture of the product.A lot history review (lhr) review is not possible; the manufacturing lot number that was provided is incorrect.
