This is filed to report the hemostasis valve break that occurred with the steerable guiding catheter, which has the potential to cause or contribute to air leak/embolus.It was reported that this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4.The steerable guiding catheter (sgc) was advanced to the left atrium.During and attempt to insert the clip delivery system (cds) into the sgc, the cds could not be inserted past the key.Four to five attempts were made, but it was observed that the sgc hemostasis valve was turning, and that the hemostasis valve and the holder could be rotated completely.The blue markers could not be aligned; therefore, the device was replaced and a new sgc was used successfully with the same cds.One clip was implanted and the mr was reduced to 1-2.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

(b)(4).Evaluation summary: (b)(4).The device was returned for analysis, and the inability to advance the clip delivery system (cds) into the steerable guiding catheter (sgc) was confirmed.Additionally, analysis identified that the bond between the valve and the guide shaft was broken.A review of the lot history record was conducted and found no exceptions associated with this lot during manufacturing.An expanded review was conducted that identified an issue potentially related to inherent variability in the manufacturing process.Further assessment of this issue per site operating procedures have been performed, and corrective and preventative actions to address this issue are in the process of being implemented.The performance of these devices will continue to be monitored.
