American researchers have just presented a wireless implant that would measure in real time the state of health of a recently transplanted organ and the tissues that surround it, reveals Medicalxpress. Explanations.
The idea of this implant is to be able to assess the level of oxygen in the organ. It is this criterion, which when it is too low, threatens the holding of the graft. “Oxygen is a key element for the ability of our cells to create energy from what we eat, for example. Almost all tissues in the body need a stable supply of oxygen to survive” , says the study.
Go measure oxygen deep in the body
Currently, we have limited means of taking the oxygen level of the transplanted organ, on the surface. The implant would make it possible to react more quickly in the event of failure by going to take measures for the time being almost inaccessible, “deep in the human body”.
The implant works like a microscopic size sensor, equipped with the necessary tools to measure oxygen. He sends information in the form of ultrasound, i.e. an elastic mechanical wave that propagates through fluid, gaseous or liquid media. A technology frequently used in medicine, especially for ultrasounds.
The technology deserves improvement, the study concludes. Especially in terms of longevity in the human body of the implant. Another point on which the researchers continue to work: the implantation technique, so that it is the least invasive possible.
