The device was not returned for analysis.A review of the lot history record was unable to be performed as there was no batch/lot number provided.Additionally, a review of the complaint history was also unable to be performed due to the lack of batch/lot.The reported difficulty appears to be due to circumstances of the procedure.Based on the reported information, it is likely that the patient anatomical conditions, guidewire employed was damaged or deficient, or use techniques employed caused the catheter to kink¿which caused the subsequent difficulty removing the catheter and material deformation (flared tip); however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.E1: (b)(6) hospital.
