Thanks a lot for your very wise and weighted reply. Of course I entered into this business because first of all I wanted to earn some money, otherwise I should donated to charity. And your point that some applications of stents can be useless or even dangerous are also valid, but we should take in consideration the other factor - number of stent operations per 1M of population. Russia is still way back from the value recommended by WHO, which means there are still a lot of people who need stents for live-saving purpose.
