Revolutionizing Surgery: Through-Tissue 3D Printing with Focused Ultrasound

A groundbreaking 3D printing technique uses focused ultrasound and a novel ultrasound-sensitive ink to construct biocompatible structures within thick, layered tissues. This could revolutionize surgery, enabling minimally invasive procedures such as repairing heart defects without open-heart surgery. The technique leverages ultrasound's penetration ability, precisely controlling temperature to solidify the ink into intricate 3D shapes. Successful animal testing, creating complex structures, paves the way for future human applications.
