EPFL engineers have developed a neural interface that disappears harmlessly within the physique after a number of months and permits pure tissue to develop again. What’s extra, it may be implanted in a affected person’s blood vessel quite than contained in the mind, thereby avoiding the necessity for invasive surgical procedure.
Some implants like pacemakers can final for years, whereas others put on out shortly as a consequence of technical weaknesses. “New neuroprosthetic units are thinner, extra versatile and extra elastic, making them higher suited to the mechanical properties of mind tissue,” says Diego Ghezzi, a professor at EPFL’s College of Engineering and holder of the Medtronic Chair in Neuroengineering. “However that additionally makes them extra fragile and fewer sturdy.” Eradicating these implants could be troublesome, and even unattainable, as a result of it usually requires invasive surgical procedure.
A biodegradable implant for longer-term purposes
Ghezzi and his staff of engineers are growing a brand new era of biodegradable implants that get round this downside. The primary impediment they confronted pertains to the brief lifetimes of biodegradable supplies, which restrict how extensively they can be utilized. “The biodegradable neural interfaces presently being developed solely work for a
