The patient had a clotted graft and was planned for a surgical embolectomy.They were using the size 4 arterial embolectomy catheter.The catheter was added to the surgical field and during the pre-procedure test of the device, it malfunctioned when the balloon was tested; the balloon did not expand or burst, but it did not blow up and fluid leaked out from tiny holes.A 2nd catheter from the same lot was tested and it also malfunctioned.Then, a 3rd catheter from the same lot was also tested, and also had the same malfunction.A 4th catheter from a different lot was tested and worked as expected.
