One 8f fast-cath introducer sheath and dilator were received for evaluation.The reported needle insertion difficulty and dilator tip damage was confirmed.The dilator had been perforated at the distal tip and skived material was noted to exit the perforation and distal tip opening.A needle/stylet assembly from current inventory was inserted and advanced through the dilator/sheath assembly; however, the needle could not advance past the location of the perforation.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The cause of the perforation and skiving was not conclusively determined.
