Minimally Invasive Heart Surgery Research Wins N.I.H. Award

an lead to problems, such as neuromotor defects in children and stroke in adults."

Dupont is developing the instruments and robotics technology needed to perform these tasks, while partnering with Microfabrica to develop a toolbox of millimeter-scale tools that can perform a variety of delicate repairs.

"Using our EFAB(R) manufacturing process, we can economically produce tiny, robust metal tools to remove and suture tissue. These tools can be quickly designed on a computer, then fabricated without the need for assembly, even when they include dozens of moving parts. And while the overall tool is measured in millimeters, it has features measured in microns," noted Microfabrica chief technology officer Adam Cohen.

According to Dupont, the biggest benefit may be the technology's potential to help all age groups: adults, children and even fetuses. "Working with our clinical partners at Children's Hospital Boston, we're developing different instruments for each of these groups," he said. "Fetal surgery is especially exciting since, in certain cases, repairing a heart defect before birth can greatly improve the chances for the heart to develop normally."
