Manufacturer Narrative

It was reported that a patient underwent cardiac ablation procedure with a carto vizigo¿ 8.5f bi-directional guiding sheath - small where hemostatic valve separation occurred.When the dilator was inserted during the transseptal, it felt stranger hardness than during normal use, and once the dilator was pulled out, damage to the hemostatic valve was confirmed.It was confirmed after the procedure that the hemostatic valve had come off.Device evaluation details: the device evaluation has been completed.A visual inspection was performed and it was found that the hemostatic valve is dislodged inside the hub of the device.It was determined that the issue observed could be related to the incorrect insertion of the dilator into the sheath causing the dislodgment of the valve since stress marks and physical damage on the outer diameter were observed under microscope which suggest that excessive force was applied.This retuned condition was reviewed and determined it continues to be deemed mdr reportable.According to the odp (optimal performance guide), there are some precautions on inserting the dilator into the vizigo sheath.- always insert a dilator straight into the center of the sheath¿s valve to prevent damage to the valve.- do not insert a dilator at an angle, as damage to the sheath valve may occur.A device history record was performed and no non-conformances related to the reported complaint were identified.The customer complaint was confirmed.The root cause of the dislodged hemostatic valve inside the hub could be related to handling of the device during the procedure however, this cannot be conclusively determined.The odp (optimal device performance guide) provide additional instructions on how to insert the dilator into the sheath.Due to the conditions observed in the hemostatic valve, an internal corrective action has been open to address this issue.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's ref.# (b)(4).
