It was reported that sheath split and saline leak occurred.The target lesion was located in the heavily calcified left anterior descending artery (lad).A 1.25mm rotalink plus was selected for use.During the procedure, the lining inside the sheath split, the device leaked and resistance was noticed.The procedure was completed with a different device.No patient complications reported and the patient's condition was fine.

Device evaluated by mfr., eval summary attached, method codes, result codes, conclusion codes updated.Device evaluated by manufacturer: the device was returned for analysis.The unit was returned with a guide wire running through the device.The guide wire was able to be removed from the device without issue.The unit was returned with blood present in the catheter sheath.A visual examination of the complaint unit was carried out, the advancer knob was locked upon return in a backward position; it was loosened and advanced in order to inspect the handshake connection.The handshake connection was inspected and no damage was noted.A handshake connection test was attempted to examine the integrity of the connection.No issues were noted.Tightened marks were noted on the sheath where the hemostasis valve was tightened.An attempt was made to wet test the device and the sheath leaked approximately 19cm and 21cm from the strain relief.The catheter sheath was examined and was noted to be torn 21cm from the strain relief.The coil was noted to be stretched where the sheath was torn.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause has been determined to be use/user error as the condition of the returned device is consistent with over tightening of the hemostasis valve.The dfu states that ¿if the hemeostasis valve is tightened excessively, it can crush the sheath around the drive shaft and cause permanent damage to the rotalink catheter.The hemeostasis valve should be closed just tight enough to prevent blood loss, but still allow the rotalink sheath to slide through the valve¿.(b)(4).
