IUI Pump?

Julie
Does anyone have experience with the IUI pump method? I went to a different doc today and due to OH's sperm he thinks that should be our next step as everything with me is ok. 
​He said we would do injections and then iui with pump as it seems I'm clomid resistant as I only had 1 follicle on clomid.  
​Any success/failed attempts with the pump method? 
​Any advice?
