Apparently, someone has put one of these together: http://newsfeed.time.com/2012/05/30/mit-invents-star-trek-needleless-injections/?hpt=hp_t3
Pretty cool stuff, if true.

Very cool. But, two points:
It's interesting that they're able to deliver medicines right into the eye and through the tympanic membrane -- presumably without damaging either.
- I don't trust any man if I can't see his lips move when he talks.
- Would it have killed someone to let us hear the hypo in use? I was really hoping to hear if it made the old, familiar hiss. I bet it makes a really scary noise instead. Just because it's a needle.

Yes this was cool indeed. Loved it.
I could not agree more with your point two. I really wanted to see this thing used.
Problem is, due to its specific purpose, I would think that demonstrating its use may be tricky. I suppose one could inject simple inert saline solution. You would hear the "hiss" or "pop" or whatever sound it makes, but you likely wouldn't see any mark on the skin, nor would there be any particular way to "prove" that it works.
I suppose one could get some...well...pig skin, thin it out a bit and inject that. In theory, you should see whatever was injected (maybe green food coloring in this case) and watch it dripping down underneath the inner skin layer and showing an unbroken outer skin layer. Seriously demoing this particular device may become somewhat gruesome. But it definitely has some great potential in the treatment of chronic diseases. I, for one, am Type 2 diabetic. Manageable through medication for now, but not at all looking forward to the day that I might have to take the needle. This would definitely help alleviate that trepidation.

Jet injection is nothing new.
http://en.wikipedia.org/wiki/Jet_injector#History
1960: Aaron Ismach invented and patented the Jet Injector medical device which was used for quick mass vaccination for smallpox and other diseases. Ismach was assisted by Dr. Abram Benenson in developing the Jet Injector Gun. The new method met with tremendous success as teams vaccinated large numbers of people at collecting points in the affected countries. The foot operated gun was called the Ped-O-Jet and the electric operated gun was called the Jet Injector Gun.
1962: Robert Andrew Hingson claimed to have invented a prototype jet injector and called it the peace gun, for quick mass vaccination. But sometimes the injection process dislodged infected matter from a patient onto the nozzle of the injector, risking cross-infection.
1964: Aaron Ismach was presented with a Gold Medal from the US Government for his efforts related to the Jet Injector Gun. The Jet Injector also appeared on postage stamps as a commemorative of his efforts.

If it's been around so long, why is nobody using it?
I received such an injection back in the 1970s. The unit itself vaguely resembled a gun, and it was a clunky affair with a hose leading to what I assume was a compressed air reserve. It was noisy, too, and I remember flinching at the sound as it delivered its payload into my upper arm. It wasn't exactly painless, either. Instead of feeling like I'd gotten one carefully administered injection, it felt more like someone punched me in the arm with brass knuckles mounting an array of needles. This was industrialized medicine lacking any real grace and having nothing in common with either Dr. McCoy's sickbay or even a contemporary physician administering the vaccine with a bit of tender consideration.
I walked away feeling like I'd just been riveted. And I had a circular reverse-hickey that was very tender to the touch.
So to sum up, you're talking about an expensive contraption that has a lot of parts to be maintained, frightens small children, and will likely get you shot if you wield one in the presence of a trigger-happy cop. I think they're only practical when engaged in mass vaccinations where kids have no say in the matter and the police have been notified in advance.
Don't really see what's so innovative here. I've owned a needle-free injection system for about 5 years. The military has used them for decades. Heck, I remember being inoculated for something with a needle-less system way back in junior high, and that would have been in the early 1970s.
The only real difference I can see between my hypo and this, is that my unit uses a CO2 cartridge to drive the delivery piston instead of the electronic actuator of this newer system. Beyond that, the description of this device reads pretty much identical to the features in my hypo's user's manual.
