Biodegradable Flow Diverter

Biodegradable flow diverters (BDFD) is a new concept for the endovascular treatment of cerebral aneurysm. BDFD primary goal is to avoid the negative log-term hemodynamic effects of metal flow diverters.

The new concept was initially proposed in 2019 by a group of Japanese researchers who published an in vivo study using animal models. The BDFD was made from poly‐l‐lactic acid wires and was completely degraded in 18 months. In the in vivo experiment, aneurysm occlusion rates were 0% at 1 month, 20% at 3 months, 50% at 6 months, and 33% at 1 year.
