That could enable them to coordinate the triggering of multiple wireless pacemakers in separate chambers of a patient&#8217;s heart, Yang said.<\/p>\n<figure class=\"mb-4\" itemscope=\"\" itemtype=\"http:\/\/schema.org\/VideoObject\"><meta itemprop=\"name\" content=\"Timing is everything in new implant tech\"\/><meta itemprop=\"url\" content=\"https:\/\/www.youtube.com\/watch\/?v=W0KbaK67PoM\"\/><meta itemprop=\"description\" content=\"Timing is everything in new implant tech\"\/><meta itemprop=\"uploadDate\" content=\"2021-05-10T14:54:25-04:00\"\/><meta itemprop=\"embedUrl\" content=\"https:\/\/www.youtube.com\/embed\/W0KbaK67PoM\"\/><meta itemprop=\"thumbnailUrl\" content=\"https:\/\/img.youtube.com\/vi\/W0KbaK67PoM\/maxresdefault.jpg\"\/><br \/>\n             <iframe loading=\"lazy\" title=\"Hydra stimulation with MagNi\" width=\"640\" height=\"480\" src=\"https:\/\/www.youtube.com\/embed\/W0KbaK67PoM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<\/figure>\n<p>&#8220;We show it&#8217;s possible to program the implants to stimulate in a coordinated pattern,&#8221; he said. &#8220;We synchronize every device, like a symphony. That gives us a lot of degrees of freedom for stimulation treatments, whether it&#8217;s for cardiac pacing or for a spinal cord.&#8221;<\/p>\n<p>The lab tested its tiny implants, each about the size and weight of a vitamin, on tissue samples, live hydra vulgaris and in rodents. The experiments proved that over at least a short distance, the devices were able to stimulate two separate hydra to contract and activate a fluorescent tag in response to electrical signals, and to trigger a response at controlled amplitudes along a rodent&#8217;s sciatic nerve.<\/p>\n<p>&#8220;There&#8217;s a study on spinal cord regeneration that shows multisite stimulation in a certain pattern will help in the recovery of the neuro system,&#8221; Yang said. &#8220;There is clinical research going on, but they&#8217;re all using benchtop equipment. There are no implantable tools that can do this.&#8221;<\/p>\n<p>The lab&#8217;s devices, called MagNI (for magnetoelectric neural implants) were introduced early last year as possible spinal cord stimulators that didn&#8217;t require wires to power and program them. That means wire leads don&#8217;t have to poke through the skin of the patient, a situation that would risk infection. The other alternative, as used in many battery-powered implants, is to replace them via surgery every few years.\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Magnet-controlled bioelectronic implant could relieve pain\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                IEEE&#8217;s Custom Integrated Circuits Conference, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/vlsi.rice.edu\/upload\/CICC_Yu_10_1.pdf\">vlsi.rice.edu\/upload\/CICC_Yu_10_1.pdf<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Rice University<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.rice.edu\/\"><br \/>\n                                                        <svg><use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/><\/svg><\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Timing is everything in new implant tech (2021, May 10)<br \/>\n                                                 retrieved 10 May 2021<br \/>\n                                                 from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2021-05-implant-tech.html<\/p>\n<p>                                            This document is subject to copyright.
