Nice, I've never heard of this "dechoking" method. I'm guessing you need one of these types of vacuums: http://www.tipa.eu/fotocache/bigorig/08850298.jpg and then you put your mouth around it?
On the cost side, you can probably get a nice vacuum cleaner for $150 :)
I'm still wondering about how effective vs. how risky this technique might be though
