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 of a leaking chronic catheter was confirmed and the cause appears to be use related.The product returned for evaluation was one 9fr d/l hickman catheter.The damage observed in the returned sample was characteristic of over-pressurization (burst) damage.This can occur through the use of syringes smaller than 10ml, by flushing against an occlusion, or due to excessive force applied during infusion procedures.The returned product sample was evaluated and a split was observed just distal of the bifurcation, on the white-lured lumen side.This catheter damage was typical of a burst, and the characteristics observed which supported this type of failure included: 'c' shaped split.Tensile weakness at the fracture site (due to material ballooning prior to burst).Granular fracture surface texture (typical of tearing failure modes).The catheter material was visibly lighter in color at the fracture site.An examination of the catheter structure revealed no potential damage/defect related to manufacture of the product.Reference (b)(4) for further information about this failure type.The product nursing guide provides the following guidance pertaining to occluded or partially occluded catheters: ¿to avoid catheter rupture, do not force entire amount into catheter if strong resistance is felt.¿ a lot history review (lhr) is not possible since a valid lot number was not provided by the complainant.
