Evvv's intracranial stent goes for 10gs a pop. Also their cement onyxx for inracranial aneurysms goes for 10g's a pop as well.
I always loved their products but never got around to buying their stock.
I made the same mistake with Kyphon.
I think delcath will turn out to be a commercial dog. To much competion from cryo, RF ablation, chemo embolisation and cyberknife type focused XRT. Its just my opinion but it is what I do for a living.
