The regenerative capabilities of our body, despite the large reserves, are very limited, especially if the issue concerns the restoration of internal organs after damage. And experts from the Boston Pediatric Hospital recently presented an implantable medical robot that can stimulate the growth of damaged structures without interfering with their work and without causing rejection by the body.
First of all, the robotic medical system is designed to treat atresia of the esophagus – it is an innate underdevelopment of the esophagus with a complete lack of physiological clearance and obstruction. At this time, this pathology can be cured with reconstructive surgery or a special method of traction (the so-called Focker procedure). And for the latter method the patient should be in a medical coma for 1-4 weeks.
A new implant robot not only allows the patient to be conscious, but also does not require particularly strict bed rest. It is fixed on the esophagus and itself is covered with a soft, biologically inert envelope. The robot is secured with two special ring-shaped fasteners, which slowly “pull” the esophagus, stretching it in the right direction. In the course of experiments on animals, tissue growth of up to 2.5 millimeters in 24 hours was achieved. In this case, the animals showed no signs of discomfort, and the organ itself retained its diameter. As stated by one of the authors of the study, Dr. Pierre Dupont,
“No one knows the optimal force that should be applied to stimulate organ growth. The robot can determine the necessary amount of force and apply it as accurately and effectively as possible. “
