Now this is fucking cool! Sure it will probably take some time to become affordable, but that it's possible at all is awesome.

How does this handle activities that require increased blood flow? Does it have a little rheostat you crank to 11 when it's time to go for a jog or something?

That sounds strampunk af, I'd get it even if I didn't need one if it did that!

[–] biggerbogboy@sh.itjust.works 26 points 7 hours ago (2 children)

Apparently you can live with a BiVACOR TAH for around 10 years without replacement due to the Maglev system inside it.

Gosh it feels like cyberpunk 2077 is just a few years away, we just need more corporate built cities.

[–] orrk@lemmy.world 6 points 33 minutes ago

oh yay, a techno dystopia, just wait for the repo men after you miss your heart payment

[–] Petter1@lemm.ee 16 points 7 hours ago

America is on track I’d say, Musk n Zuck are so horny to do that…

Now time to make it look like some DeusEx heart

[–] Skanky@lemmy.world 13 points 8 hours ago (4 children)

Not to belittle this accomplishment, but how is this a "World's First" success?

https://en.m.wikipedia.org/wiki/Artificial_heart

[–] Lv_InSaNe_vL@lemmy.world 20 points 7 hours ago (1 children)

Because I read the article I actually know the answer! It's the first time this technology has been used in a human, and it's been a huge success so far. Quote from the article

The BiVACOR total artificial heart, invented by Queensland-born Dr Daniel Timms, is the world’s first implantable rotary blood pump that can act as a complete replacement for a human heart, using magnetic levitation technology to replicate the natural blood flow of a healthy heart.

[–] SkyeStarfall@lemmy.blahaj.zone 3 points 5 hours ago (2 children)

It would be nice if the article said if the artificial heart includes functions such as pumping harder in response to exercise and such, because it isn't entirely clear if it does

Maybe it's implied, but I feel it should be explicitly mentioned

[–] MaggiWuerze@feddit.org 3 points 1 hour ago (1 children)

I actually asked this very question in another post and got a technician who worked on this to answer: https://feddit.org/comment/5284139

[–] kiagam@lemmy.world 2 points 5 hours ago (1 children)

Other prosthetic/mechanical changes to hearts don't do that, so I would guess this one doesn't either. It would require interfacing with the brain and decoding stimulus, which would be much more complex.

Usually the recipents just keep activity low or pass out when they need the energy/heat dissipation and can't get it.

[–] SkyeStarfall@lemmy.blahaj.zone 4 points 5 hours ago

Yes exactly, so when they call it a "total heart replacement" I'd like to have clarification on it, so that I know how excited I should get

It's frustrating when articles on new innovations don't go into details about them at all except just "it exists" pretty much

[–] roofuskit@lemmy.world 7 points 8 hours ago* (last edited 8 hours ago)

Likely the length of time is what's first.

Edit: nope several people have had them for over 100 days

[–] vrighter@discuss.tchncs.de 1 points 8 hours ago

it was first invented by Tigger, too!

[–] Hux@lemmy.ml 108 points 13 hours ago* (last edited 13 hours ago) (9 children)

Did some fuckin’ Aussie heart surgeon just breeze into a Home Depot and saunter into the plumbing aisle in his board shorts and flips flops and just whip together a heart out of brass fittings and teflon tape???

“Oi! DANNY, YA FUCKIN’ BOGAN! I DONE DID YA UP A NEW RICKY TICKEY—ALL FUCKIN’ SHINEY AND CHROME!!! GRAB A CARPET KNIFE AND SOME DUNNY GLOVES—WE’ll GET THIS FUCKER INTO YOUR BLUDGER CHEST BEFORE YA SHEILA SAYS YA WERE CHUCKING A SICKIE!”

[–] MaggiWuerze@feddit.org 1 points 1 hour ago

Funny you would say that, the inventor credits trips with his father to Bunnings as inspiration for his work

For orthopods though, using power tools and sledgehammers is pretty much the name of the game.

[–] sem@lemmy.blahaj.zone 6 points 6 hours ago

I just gotta say.

Photoshopping is such a great skill to have. Thank you for making my day better.

[–] nightlily@leminal.space 3 points 6 hours ago

Bunnings is the appropriate hardware store franchise here. He of course would have grabbed a Snag outside on the way home

[–] synapse1278@lemmy.world 22 points 11 hours ago (2 children)

Function over form, I suppose. I am pretty sure it's mostly made of titanium and silicone.

It does seems like that sometimes tho, that surgeons are the mechanics of the human body, fixing you up in the most crude ways, as long as it gets the job done.

[–] Excrubulent@slrpnk.net 11 points 10 hours ago (1 children)

Friend of mine who'd been in the room for bone surgeries said it was basically just carpentry. All saws, drills & screws.

[–] toynbee@lemmy.world 2 points 6 hours ago

It's been a while since I watched the video, but I think I remember this guy having some interesting things to say about surgeries. The things I vaguely remember align with what you said.

[–] nodiratime@lemmy.world 5 points 10 hours ago* (last edited 9 hours ago)

That's the reason a friend of mine once said that surgeons are the only Doctor meds he has respect for.

Also, what do you mean form follows function? It looks like a fricking mini turbo charger 😎

[–] 2deck@lemmy.world 30 points 12 hours ago (1 children)

The surgeon yelled

WITNESS!!

And thrust the heart into their chest.

SHINY AND ~~CHROME~~ TITANIUM

[–] RedditRefugee69@lemmynsfw.com 4 points 7 hours ago

I think chrome references the color, not material. They called chrome colored cake paint "chrome."

[–] TheWinged7@lemm.ee 18 points 13 hours ago

It'd be a Bunnings down here not home depot, but it sure looks like it

[–] Cris_Color@lemmy.world 258 points 16 hours ago (1 children)

The Australian researchers and doctors behind the operation announced on Wednesday that the implant had been an “unmitigated clinical success” after the man lived with the device for more than 100 days before receiving a donor heart transplant in early March.

Just in case anyone else also found the title ambiguous regarding whether "100 days" meant he died 😅

I wonder if his mates will forever call him “Tin Man”.

[–] werefreeatlast@lemmy.world 5 points 9 hours ago

I am titaneeeuum!

[–] original_reader@lemm.ee 84 points 16 hours ago (1 children)

First of all: congratulations. Seriously. This is awesome! Secondly: you designed the most Steampunk looking heart you could. Bravo, truly a capital marvel of fine craftsmanship.

[–] daddy32@lemmy.world 3 points 1 hour ago

Yes, I opened the article just to find an answer to the question: Does it really look this fucking cool? Answer: yes, yes it does.

[–] aeronmelon@lemmy.world 21 points 13 hours ago

That thing looks so steampunk, I’m kinda jealous.

[–] andrewrgross@slrpnk.net 18 points 14 hours ago (1 children)

That's fuckin' nuts.

Also, this headline is bad. I thought he died. No. He just got a transplant after 100 days (whew).

[–] Grass@sh.itjust.works 5 points 12 hours ago

it would be so fucking cool if he still had it but it really is uncharted territory

[–] OhVenus_Baby@lemmy.ml 24 points 16 hours ago* (last edited 16 hours ago) (5 children)

This might be sort if news. I know a guy that had a pump for a heart it pumped the same non stop pressure and he wore a satchel type battery pack forever but functioned fairly normal. Always had to keep extra batteries around and the internal pump had a backup of 30 to 45 mins. This was 15 years ago.

[–] Willy@sh.itjust.works 1 points 5 hours ago

Yeah, my dad was on a bivad 25 years ago for almost a year. Back then it was the size of a washing machine. By the end of his hospital stay they introduced the satchel kind with batteries.

[–] Resurectra@lemm.ee 13 points 14 hours ago (1 children)

Sounds like a Left Ventricular Assist Device (LVAD)! They’re still being used today, although usually as a bridge to transplant rather than definitive therapy.

This new development is definitely exciting though, hopefully it will offer a new longer term alternative for patients :)

If it was the same pressure all the time, does that mean he couldn’t do anything that would otherwise cause a normal heart to beat faster (run, exercise, feel nervous)? Would he faint or something since his “heart” won’t beat faster?

[–] OhVenus_Baby@lemmy.ml 14 points 14 hours ago* (last edited 14 hours ago)

So his heart was pronounced dead, it didnt function but was left inside I think. I always wondered his abilities and I asked once that very question, particularly towards having sex lol. He used to be an alcoholic and could no longer drink as it would thin the blood and thus mess with the pumping ability.

I don't recall him ever doing anything strenuous and truthfully don't recall his answer to that question but seems like he joked that he could still do it with a woman. He walked slow, talked slowish labored sort of, laughed sheepishly like a labored laugh. Generally looked sick like you can imagine. He drove cars and that's about all I remember. Im unsure if he could turn it up maybe? I haven't spoken with him in a decade. I don't even know if he is still alive.

He got robbed/mugged in a big city about 10 years ago, the mugger took his satchel containing his medical battery bank despite him explaining the battery pack and pleading at gunpoint on a downtown street. He nearly died and an ambulance couldn't arrive in time. A stranger he flagged on the street transported him to a hospital where they somehow got him hooked up to a new battery system. They said he had mere minutes left on the internal battery inside his pump. That was the last info I heard of him. Wild to think about and he told the robber it was a medical pack but they thought it was a laptop bag and took it anyhow, it was more square like a car battery than a satchel but more vertical shaped like a rectangle.

I wonder if there'll ever be artificial heart that would last for decades, I imagine that would save lots of people.

[–] nyan@lemmy.cafe 3 points 7 hours ago

I imagine that would save lots of people.

Lots and lots and lots. All the issues with scarcity of donor hearts and tissue compatibility would just go away, and the main constraint on heart transplants would become the availability of a cardiac surgeon. Far fewer people would die while they were on a waiting list, and there would be much less incentive to drop anyone healthy enough to survive the surgery off the list entirely.
