"In fact, just prior to our pausing the neuromodulation program, we

performed a successful acute first in man test in Europe with
prototype electrodes and an external pulse generator. The testing
showed a clear and immediate physiologic response with drops in
both heart rate and blood pressure. These results strengthen our​

conviction that we have identified a significant clinical opportunity"


"We also filed two neuromodulation patent

applications in the third quarter of 2016. In the future, we will
consider alternative opportunities to fund the development of this​

valuable technology."


Is it possible they didn't want to do anything till they get the patents?  as someone could quickly copy cat them?
How long does it take to get a patent approved in the medical field?
