      Engineers from Northwestern University have just unveiled the world's smallest pacemaker. Small enough to fit inside the tip of a syringe, this allows doctors to inject it into the body without surgery to help patients who need temporary heart pacing.

      What is this? A pacemaker for ants?

      First the titanium heart as an alternative to a pacemaker. Now a pacemaker that is less invassive and safer.

      The fact it doesn't even need an operation and fits in already commonly available biopsy needles are huge upsides. Though I wonder how long they remain functional in the body. I imagine basically getting a heart biopsy too frequently would get old pretty fast and come with other risks like accumulating scar tissue. But the upsides of not needing full blown open heart surgery, anesthesia, saving on blood transfusions, rejection drugs, and all the other costs of heart surgery is incredible. like pennies in materials and a few minutes with a nurse vs thousands dollars and hours of a full O.R. staff. The implications are actually insane.

      My grandmother underwent a pacemaker implantation. Somehow during the procedure her diaphragm nerve got damaged and she has trouble with short breath, which in retrospect made it worse for her. There are no known treatments for this and only hope it gets better over time, it has been over a year since the operation. I pray medicine science will progress so others are not troubled with the complications.

      Please bring attention to the fact the federal funding for Northwestern who developed this tech was just fully cut so it will be so much harder for discoveries like this to be made

      There is such a thing as a leadless pacemaker (two brand names of Micra and AVEIR) already. These do require surgery but are not bulky compared to the current PPM out there. They are inserted directly into the heart vs outside the heart such as this new invention

      "Galvanic Cell" that "oxidizes in the body" is a quite nice way to say you stick two electrodes into the heart so it becomes a battery. It is certainly awesome that works, but I still want to know which materials can form a battery and be absolved by the body afterwards.

      i work at Northwestern. This is Amazing technology that could save the lives of so many americans. that must be why our federal funding was just taken from us 😒

      My dad got to be one of the first to get a similar tiny pacemaker. His has no leads and is used to respond to the beat of the top of his heart. He had open heart in May 2020 (Yeah, bad timing πŸ˜‚, literally the day of Covid lockdowns) and recently all three bundle branches, the nerves that communicate between the top and bottom of the heart, were overwhelmed by scar tissue and the bottom of his heart pretty much stopped responding to the top of his heart. He had to have this little pacemaker implanted to stimulate the bottom of his heart in response to the top of his heart. It was actually his original heart surgeon's son who did the surgery to implant it

      Amazing! Especially the control of the device by near infrared light through the skin. A wireless network for the human body!!! Brilliant!

      How are you consistently so funny AND so knowledgeable?! Trust me, most people are usually one or the other. But when I need a quick brush up on science that's outside of my scope, don't want to feel like I'm working, and want to actually remember enjoying learning, you're my go to. Thanks!

      Whats even cooler is we're developing diamond batteries which can last for a century at least. These batteries are incredibly small as well, and van deliver up to 2V. Meaning it's practically PERFECT for a pacemaker
