Have anyone heard of the ultraseal device for LAA closure?

It’s made of foam, ideal for those with nickel allergies from the watchman

Dr Natale told me he read of a new foam device. I didn’t get it’s name. Perhaps it’s the ultraseal...maybe something else.

The article says the device is made of nitinol, which is exactly the same stuff the Watchman is made of. Nitinol is an alloy composed of nickel and titanium. I don't know if the Ultraseal is what Natale was referring to, but if it is it doesn't solve anything for you.

The thing is, just because you have a nickel allergy doesn't mean you have a nitinol allergy. You really should let them test you by taping a Watchman to your skin for a week as they suggested.

Best alloy for these uses is unobtanium but it's awfully hard to get.
