Back before Omar Ishrak retired last year as the chief executive of Medtronic PLC, run out of Fridley, it's unlikely the board ever gave him $15 million to buy whatever he wanted. Yet Medtronic seems ready to give that to him now that he's the co-founder and chairman of the board of something called Compute Health Acquisition Corp. What Compute Health will do with Medtronic's money can't be known, because this is a special purpose acquisition company, usually called a SPAC or a blank check company. It's going public without a business, so there's nothing to analyze or carefully weigh against any other alternatives for Medtronic's $15 million.
