Insurance costs are already low - they only make 4% profits.
Of those the better services we are receiving as a result of new technology accounts for most of the high costs. It just costs more to do a triple bypass that we can do today than to watch a person die back when we were unable to do a triple bypass. When you get more you pay more. However, just like TV sets do a whole lot more than they did 30 years ago and at times we had to pay for those improvements, eventually the prices of improved set came down through innovation.
As have the price of computers, paid $1500 for a computer with 256k memory and two disk drives. Now, less than $500 for 6GB memory, huge hard drive, etc. Prices for computers have come down. I get more but pay much less even without considering inflation of dollars since then.
Now, (remember you say innovation reduces price), when is the price of health care going to come down because of innovation? The price of health insurance has skyrocketed for more than 30 years. Just when is your wonderful "innovation" going to kick in to reduce costs?
If you follow the money, doctors say they are not getting it, the hospitals say that they are not getting it, the expensive equipment is eventually paid off via high charges to patients (and the new equipment is worn out and must be replaced like the computer example, the costs should be lower), and the insurance companies say they are only getting 4% profit (they are not getting it), so again, where is the money going?
Profits by medical industry:
Medical REITs earn about 24% profit
Drug manufacturers earn about 16% profit
Drug delivery earns about 13%
Healthcare information services earn about 9%
Home health care earns about 8%
Medical labs and research earn about 8%
Medical instruments and supplies earn about 7%
Generic drugs about 6%
Hospitals about 3%
health care plans about 3%

So when you buy a generic drug about 6% of your bill is going to the manufacturer of that drug. When you have a hospital stay about 3% of the bill is kept by the hospital, etc.
When innovation brings down the costs of instruments which are bought by many in the field it will be reflected in the bill, but it will only account for a cut in the 7% of the portion of the bill that is due to instruments.
The largest costs as for any industry is in labor. If you have nurses 24 hours a day when in the hospital then there are three shifts with several nurses in each and each one is earning maybe $60,000 per year. It adds up.
