Scientists in Canada have developed a new system of platinum implants to monitor brain aneurysms that is less invasive and more accurate than current methods.

Brain aneurysms - a bulging artery - can rupture and lead to stroke, brain damage or death.

To stop the blood flow to the weak area of the artery, surgeons typically insert an embolization implant made of microscopic coils of platinum.

Researchers at the University of British Columbia have now devised a monitoring technique that is compatible with existing coil-implantation tools and procedures.

The team proved that it is possible to use the platinum implant as an "antenna" to wirelessly detect blood levels and indicate implant failure.

Results of the study will appear in a forthcoming issue of the Elsevier journal Biosensors and Bioelectronics.

"This is a completely brand new approach to monitoring cerebral embolization and our tests in the lab have been quite successful," said lead author Kenichi Takahata, an assistant professor in the Department of Electrical and Computer Engineering.

"As an early detection method, what we're proposing could be carried out by patients at home on a continual basis," he explains.

A prototype device could be developed within two to three years, Mr Takahata added.
