It was reported that during the procedure, the dragonfly opstar imaging catheter got stuck on the guidewire and both were removed together as a single unit.The pullback image was correct, and the procedure was complete at this point therefore no other optical coherence tomography device was used.There were no adverse patient effects and no clinically significant delay during the procedure.No additional information was provided.

Visual and functional analysis was performed on the returned devices.The reported difficulty removing was unable to be confirmed.The dragonfly was returned with an unknown guidewire secured with dried contrast, inhibiting removal.However, the dried contrast was removed, and the unknown guidewire was removed.A proxy guide wire was backloaded through the mini rail of the dragonfly with no resistance noted.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar complaints reported from this lot.Based on the information received and analysis of the returned device, the investigation was unable to determine a cause for the reported difficulties.A proxy 0.014-inch guidewire was backloaded through the mini-rail with no resistance noted.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
