Visual analysis and functional testing were performed on the returned device.The reported leak and catheter damage (perforation or tear in sheath) issue was unable to be confirmed, as the device functioned as intended.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.A query of the complaint handling database for the reported lot was performed and revealed there is no indication of a lot level quality product issue.The investigation determined that the reported leak and catheter damage (tear or perforation in catheter sheath) could not be confirmed, as the device functioned as intended.It may be possible that customer is unaware of the optis and opstar models both having a designated purge hole, which is distal to the lens and proximal to the guidewire exit port, and differs from previous dragonfly models that have purged liquid exit through the guidewire exit notch/port; 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.D4: correction lot# from unknown to 8436616.
