As reported, two 6f infiniti 3.5 x 100cm jr angiography diagnostic catheters of the same catalog and lot numbers were involved in the same procedure/same patient.These two devices were both found crack upon removal, which was suspected to be related to preoperative plasticity.The surgeon reshaped the product by hand according to the anatomical features of the patient and experience.The reshaping of the catheter was performed in the area of cracking/separating.One of them was pulled into two pieces outside the patient by the surgeon.Another cordis device was used to get the procedure completed.There was no reported patient injury.Only one picture of the device was retained.The intended procedure was an angiography.The product was stored, handled, and prepped according to the instructions for use (ifu).There was no device damage noticed prior to opening the package nor difficulty removing the device from the sterile packaging or prepping the device.The access site was radial.The target lesion was the right coronary artery.Lesion calcification, vessel tortuosity and percentage stenosis are unknown.It is not known if the devices were being used for a chronic total occlusion (cto).Force was used for reshaping the device before use; it is not certain if the devices were over torqued or if the catheters were ever in an acute bend.The device did not kink; it was bent due to reshaping.There were bends noted before the event occurred.The devices were found crack after use.Neither the products nor any of the other devices used with it had been re-sterilize.The devices are expected to be returned for evaluation.
