NTU Singapore Scientists Develop System to Deliver Electrically-activated Glue for Sealing Defects in Broken Blood Vessels

New device offers a quicker, less invasive way to seal tears and holes in blood vessels


New device offers a quicker, less invasive way to seal tears and holes in blood vessels
A team of researchers led by Nanyang Technological University, Singapore (NTU Singapore) has developed a device that offers a quicker and less invasive way to seal tears and holes in blood vessels, using an electrically-activated glue patch applied via a minimally invasive balloon catheter.
This device could eventually replace the need for open or keyhole surgery to patch up or stitch together internal blood vessel defects.
After inserting the catheter into an appropriate blood vessel, the glue patch - nicknamed Voltaglue - can be guided through the body to where the tear is located and then activated using retractable electrodes to glue it shut in a few minutes, all without making a single surgical cut. ....

Scientists from Nanyang Technological University, Singapore (NTU Singapore), have developed a new way to cure adhesives using a magnetic field.
Conventional adhesives like epoxy which are used to bond plastic, ceramics and wood are typically designed to cure using moisture, heat or light. They often require specific curing temperatures, ranging from room temperature up to 80 degrees Celsius.
The curing process is necessary to cross-link and bond the glue with the two secured surfaces as the glue crystallises and hardens to achieve its final strength. ....
