3D-Printed Sugary Stent Holds Arteries for Suturing

Jan-26-19 A 3D-printed sugar-based vascular stent helps hold small arteries together during surgery.

One of the challenges of vascular surgery is stitching the ends of the arteries back together—a common process in a wide array of procedures. To make the delicate task easier and more efficient, the team from the University of Nebraska-Lincoln created a tube containing the glucose derivative dextran. This sugary substance provides both an adhesive quality to hold the stent in place during suturing while also helping to prevent clotting. The stent will also be absorbed safely by the body after the artery has been sealed.
