Malone. Yes. You are correct, it was related to a W/E puzzle. I was trying to avoid spoiling. I had another gripe with the same puzzle. I don't see 'stent' and 'spare' being synonymous. You don't have a stent from birth. I'm aware of the phrase 'spare part surgery', but still not happy with the clue. I'm just becoming an old curmudgeon, as Columbine keeps saying. ;-)
