Corrupted WiredTiger.wt

As some other people, our WiredTiger.wt has been corrupted during a maintenance operation. And unfortunately we cannot restore the data as we had synchronization problems with the secondary. 

Restarting the mongod instance with the --repair does not go further than without it. 

Apparently there is a tool made by MongoDB to repair it. Would it be possible for someone to use it on the attached files?
