Scientists develop conductive polymer patch designed to help repair damaged heart

After a heart attack, some beating heart muscle tissue was eventually replaced by unbeat scar tissue – permanently damaging the heart’s function,media New Atlas reported. But scientists are now devising a new patch to help. The device was developed by a research team led by Michael Monaghan, an associate professor at Trinity University in Dublin, Ireland, to connect to the outside of the heart and bridge the area of scar tissue.

The patch is made of a medically recognized stretchable polymer and coated with a separate conductive polymer- polypyride coated with a mesh. This was done through the “melting straight writing” technology developed by Spraybase, a derivative firm at Trinity University in Dublin.

It is hoped that once implanted in the heart, the patch will be able to obtain electrical signals from the surrounding heart cells, spread their signals across gaps, and expand and contract with them in time. So far, researchers have tested the patch on biological tissue from the body and plan to conduct animal experiments.

We have previously seen other experimental “heart patches” designed to perform similar functions. Although many of them integrate actual living heart cells, this new patch is designed to work alone – although it can also work with added cells to enhance function.

A paper on the study was recently published in the journal Advanced Functional Materials.
