It was reported via a hot line call.The rn for the cath lab is calling because the chief of perfusion asked that she let us know about their difficulty due to "repeated problems as stated by the chief of perfusion" the rn stated that they inserted the intra-aortic balloon (iab) and on the pump (40101w) and they had persistent "low helium / kink" alarms.The rn attempted changing the tank, etc.Without resolution.There was no blood or kinks noted in the tubing.They were going to try another pump, but the doctor chose to remove the intra-aortic balloon (iab) (the iab serial number unavailable).A second iab was inserted via same site and a new pump was also used.

(b)(4).The device was returned for evaluation, a 40cc 8.0fr fos iab in its supplied return kit.Small areas of dried blood were noted on the bladder membrane, but not within.The one-way valve was tethered to the short fiber-optix sensor (fos) driveline tubing.The bladder membrane was fully unwrapped.No kinks, damage, or abnormalities were noted on the device.The connector and cal key were examined.The gray fos connecter was seated properly in the housing and both retaining tabs were intact.The center post of the fos was centered.The blue clamshell housing was examined and no damage was noted.The cal key was intact.The one-way valve was tested and passed.A vacuum was pulled on the one-way valve and it held for at least 1 minute and then 30 seconds five separate times.The cal key and fos were connected to the iabp.The cal key was recognized, but the fos was not recognized.The fos status was "ll pl" indicating a potentially broken fiber.The fiber was found broken approximately 1.1cm from the distal tip of the catheter.The iab was submerged in water and leak tested.The device passed leak test.No holes or leaks were noted.See other remarks section.Other remarks: a lab inventory guidewire was inserted through the distal tip of the catheter.No resistance was noted.The guidewire was able to fully advance.The guidewire was inserted through the luer end of the device, and no resistance was noted.The guidewire was able to fully advance.The iab was connected to the iabp and inserted into the t-tube.The t-tube was pressurized to 100mmhg.The pump was run for 30 minutes with no alarms noted.A device history record (dhr) review was conducted for the lot number/serial number with no relevant findings.The device passed all manufacturing specifications prior to release.Conclusion: the reported complaint of the pump alarming for low helium and kinks is not confirmed.No kinks or bends were noted on the iab upon return.The iab was also pump tested and no alarms occurred; however, the fiber was found broken, and the iab could not establish a light path with the pump.The root cause of the complaint is undetermined.We will continue to monitor for similar complaints.
