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), applicable manufacturing records, photo analysis and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of difficulty inserting the introducer was confirmed but the cause is unknown.A single photograph of a 3.5fr microintroducer/dilator/sheath was returned for evaluation.The dilator was inlaid within the sheath and the sheath handles had not been split.It was reported that splits were seen at the transition between the dilator and sheath.No tears or splits were evident in the sheath material in the photograph.However, it is possible that the damage had occurred on the side of the sheath that was not visible in the photograph.The sheath material did appear to be slightly flared away from the dilator shaft and the dilator shaft was slightly bowed.These characteristics are indicative of difficulty inserting the introducer.However, the root cause of the difficult insertion could not be determined.Possible contributing factors could include too small of an incision, a steep insertion angle, a poor transition of the introducer sheath to the dilator, or damage to the sheath prior to use.Sheath damage can be minimized by simultaneously advancing the sheath and dilator as a single unit using a rotational motion.If necessary, a small incision may be made adjacent to the guidewire to facilitate insertion of the sheath and dilator.H3 other text : evaluation findings are in section h.11.
