I'm not a long time follower of VPHM but the past year or two they seemed to be especially sensitive to competition questions maybe that is just addressing what the analysts were asking but before discontinuing it they were quite hopefully with the HALO sub-q. I think they did a good service to their shareholders and picked a good time to sell but time will tell :-)
I did do a quick listen to the call and they said they are still open to other deals though it seems like it will be a while... I think an ERT company would have offered a lot of synergy too :-).
