As reported, that during a left heart catheterization (lhc) procedure, the doctor attempted to gain access into the radial artery and when he tried to insert the wire of 6f 10cm transradial rain sheath introducer it would only go so far and then not advance anymore.They tried gaining access for approximate 20 minutes.When they tried to remove the wire through the needle, it was reported that the wire was stuck and would not come out.Another doctor was eventually called in to the room to try to assist.At some point the wire was removed, but the tip of the wire had broken off and the new distal end had sheared.A vascular surgeon was called in to try and retrieve the distal tip but was not successful.They performed a cut down of the artery and as reported by the tech, the distal tip was not visible in the artery but was retrieved from the muscle.Another nurse in the room had the same account of the procedure, however, the vascular surgeon did not dictate that in his notes.The patient was ok and went home the same day.Therefore, the left heart catheterization (lhc) procedure was completed by going in through the femoral artery access.The operator was trained to the transradial rain sheath introducer device.The device was stored in the cath lab with the rest of their product, for a few weeks.The device was stored, handled and prepped according to the instructions for use (ifu).There was no difficulty experienced in prepping the device.There were no anomalies noted prior to inserting into the patient.There was no damage noticed to the device prior to opening the package.There was no difficulty removing the device from the sterile packaging.There was difficulty gaining access.The wire kinked while being used.The lesion was sot calcified or tortuous.The device was not used for a chronic total occlusion.The device will be returned for evaluation.
