Elastic glue seals wounds in 60 seconds
Biomedical engineers from the University of Sydney and the United States collaborated on the development of the potentially life-saving surgical glue, called MeTro. MeTro’s high elasticity makes it ideal for sealing wounds in body tissues that continually expand and relax – such as lungs, hearts and arteries – that are otherwise at risk of re-opening.
The material also works on internal wounds that are often in hard-to-reach areas and have typically required staples or sutures due to surrounding body fluid hampering the effectiveness of other sealants.
MeTro sets in just 60 seconds once treated with UV light, and the technology has a built-in degrading enzyme which can be modified to determine how long the sealant lasts – from hours to months, in order to allow adequate time for the wound to heal.
The liquid or gel-like material has quickly and successfully sealed incisions in the arteries and lungs of rodents and the lungs of pigs, without the need for sutures and staples.
