Nature Biotechnology<\/a>, researchers report that the device reliably kept the heart\u2019s pace in check in tests on mice, rats, and other animals, as well as in human heart tissue in a dish. And while the research is still in the early stages, the scientists say the pacemaker was able to overcome key limitations of existing devices.<\/p>\n\n\n\nUnlike traditional pacemakers, which are left inside a patient for the rest of their life or until the battery dies, a traditional temporary pacemaker is implanted and later removed. The devices are typically for children with congenital heart defects or adults who have had a coronary artery bypass graft, who may need a temporary pacemaker to correct a slowed heart rhythm for only a few days or weeks.<\/p>\n\n\n\n
A traditional temporary pacemaker has wires connected to the heart, which poke out of the skin and attach to external hardware. Some experts say that setup could raise the risk of infection, potentially injure the heart when the lead is removed, and can hamper patient mobility. Being able to move around after surgery is especially valuable as patients recover.<\/p>\n\n\n\n
The new device overcomes some of those challenges with the help of an external coil that can be sewn into a patient\u2019s shirt or placed as a patch on the patient\u2019s chest, where it transmits energy to power the pacemaker.<\/p>\n\n\n\n
Because all of the complex programming for the pacemaker is done not in the device itself, but in external hardware, it isn\u2019t confined by circuits that would otherwise be needed to communicate and process heart information. That means the device can be tiny and thin \u2014 less than a millimeter thick \u2014 which makes it easier to implant.<\/p>\n\n\n\n
\u201cIt\u2019s restricted just by the size of the antenna, which will harness the energy,\u201d said Efimov.<\/p>\n\n\n\n
Efimov and his colleagues were able to build on past research into bioresorbable materials, which have been developed and used for other applications for years. They selected materials that could be slowly and safely absorbed by the body. The thickness or type of materials used can change depending on how long the temporary pacemaker needs to last. The materials \u2014 some organic, silicone-based, or metals like magnesium \u2014 are also relatively affordable and comparable to the costs of a typical pacemaker, according to Efimov. The primary cost for manufacturing the devices would come from the external hardware the device requires.<\/p>\n\n\n\n
\u201cIt seems to be a very revolutionary idea. I believe it\u2019s going to be well-received in the field. It targets an unmet need, and I believe it\u2019s going to benefit patients,\u201d said Mansour.<\/p>\n\n\n\n
