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.The following were reviewed as part of this investigation: patient severity, complaint and batch history, applicable previous investigation(s), labeling, applicable manufacturing records, sample analysis and applicable fmea documents.Based on a review of this information, the following was concluded: this complaint is unconfirmed because the issue could not be reproduced on the returned sample.The product returned for evaluation was a 4fr d/l powerpicc catheter.The catheter was received in two segments.The proximal segment contained the luer adaptors, extension legs, molded suture hub and the catheter to the 13cm depth marking.The other piece of returned material was the catheter tubing from just proximal of the 35cm depth marking to past the 54cm depth marking.The catheter shaft from the 14cm depth marking through the 34cm depth marking was not returned for evaluation.Red residual material was seen within both lumens and the proximal segment appeared to hold a curved radius in the catheter tubing around the 2cm depth marking.A circumferential impression was seen and felt at the 2cm and 52cm depth markings.When the catheter was manipulated by the investigator, the catheter would preferentially kink in these locations.It is likely that the catheter had been kinked previously.Microscopic examination of the ends of all the tubing fragments were examined and contained regular striations and a glossy veneer.It appeared that all the tubing ends had been cut with a sharp instrument.When an attempt was made to flush the proximal catheter segment with water from a 12cc syringe, the purple lumen was patent to infusion.Initially the red lumen was occluded.Residual material was flushed out and then the lumen became patent.When an attempt was made to flush the distal catheter segment with water from a 12cc syringe, both lumens were patent to infusion.The distal ends of the catheter segments were clamped, and the catheter segments were flushed against the occlusions.No leaks were detected in either catheter segment.As no leaks were detected, this complaint will be considered unconfirmed at this time.It is unknown if the leak occurred in the catheter tubing segment that was not returned for evaluation.Possible contributing factors that can lead to a leak in the catheter include sharp instrument damage, material fatigue, tensile (pulling) damage, and over-pressurization.H3 other text : evaluation findings are in section h.11.
