The reported event is inconclusive due to poor sample condition.Evaluation report of the returned sample, submitted by futurematrix interventional, stated that the sample was visually inspected under 7-20x magnification.The portion of the inner shaft that was contained inside the balloon was found to have a jagged end.There were markings on the broken end of the inner shaft that appeared to be forceps or other clinical procedure instrumentation.The distal end of what was left of the balloon appeared to have been bunched up or forcibly twisted.There were remains of pebax and loose fibers.Fibers were wrapped around the inner shaft as if twisted.Portholes and bullets were in place and were not defected.Due to the poor condition of the sample, the investigation could not be conducted further.The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The instructions for use were found adequate and state the following: ¿inflating the balloon catheter 1.Fill the inflation device (eagle¿ inflation device) with sterile, liquid media.2.Attach the inflation device to the balloon lumen.3.Open the stopcock and inflate the balloon.4.Once dilation has been attained, advance the sheath over the balloon.Warning: do not use air or any gaseous substances as a balloon inflation media, always use sterile liquid media.Note: the use of an inflation device with a pressure gauge is highly recommended to make sure adequate pressure is applied and the maximum limits of the balloon are not exceeded.Note: slight reduction in balloon pressure may be required if resistance is encountered when advancing the sheath over the balloon.Caution: do not exceed the recommended rated burst pressure (rbp) for this device.Balloon rupture may occur if the rbp rating is exceeded.Please refer to the device label for the recommended rbp.Deflating the balloon catheter deflate the balloon using an inflation device.Since deflation times vary based on balloon sizes and lengths, check fluoroscopically to confirm deflation before attempting to withdraw.1.Attach the inflation device (eagle¿ inflation device) and remove the solution from the balloon by pulling back on the inflation device.2.Remove the inflation device from the balloon catheter.This will allow ambient pressure to enter, relaxing the balloon.3.Gently withdraw the catheter.Use of a gentle counterclockwise twisting motion is recommended when removing the catheter.Warning: if resistance is felt when removing either the catheter or the guidewire from the working sheath, stop and consider removing them as a single unit to prevent damage to product.Applying excessive force to the catheter can result in tip breakage or balloon separation.Using the refolding tool the balloon catheter is supplied with a refolding tool.This aids in preparing the balloon for another insertion during the procedure.To use: 1.Manually compress the balloon.2.Position the refolding tool at one end.3.Twist the refolding tool counter clockwise and push down on the balloon until it goes the entire length of the balloon.4.Once the balloon is folded, remove the refolding tool and proceed with the procedure.Storage store in a cool, dry and dark place.Do not store near radiation or ultraviolet light sources as these may damage product materials." 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.
