All your points are valid. However, the features you listed all involve peripheral devices, not the pump. None of them are proprietary or patented and can be used by any manufacturer. Data acquisition and power transmission techniques will evolve. These things can be improved and refined in an electronics lab, and don't require the human body. I think the reason they are not using wireless technologies is that you can't beat a cable for reliability. The number one motto for new medical devices under testing is AVOID DEVICE FAILURES AT ALL COSTS. One failure can set the device back years with regulatory agencies. I think you will see improved peripherals once the pump is proven to work in a large number of patients.

The key factors to consider when evaluating different systems all involve the the pump itself. Some of these are (listed in order of importance):

1) Blood Cell Damage
2) Blood Clot Formation
3) Device size.
4) Power requirements
5) Device complexity
6) Failure modes
7) Reliability and device life
8) Manufacturing costs

If you really want to know if the HeartSaver has a competitive advantage, then these are the questions to ask. The old saying "Don't put the cart before the horse" directly applies to this field. Comments are welcome. I'm not an expert on the clinical side, so my views could be off the mark.
