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

May 23 2021

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.

Patented by NTU and Massachusetts Institute of Technology (MIT) scientists, Voltaglue is a new type of adhesive that works in wet environments and hardens when a voltage is applied to it.

The catheter device that deploys Voltaglue is jointly developed by Associate Professor Terry Steele from the NTU School of Materials Science and Engineering, former NTU PhD student Dr Manisha Singh, now at MIT, and Associate Professor Ellen Roche from the Department of Mechanical Engineering and Institute for Medical Engineering and Science at MIT, USA.

This catheter device is the first proof-of-concept application of Voltaglue in a medical setting since it was invented by Associate Professor Steele in 2015.
