Interdisciplinary Cerebrovascular SymposiumIntracranial Stent Meeting

13 - 14 November 2015Gold Coast, Australia Program

Welcome

WelcomeWe welcome you to the international conference for the 12th Interdisciplinary Cerebrovascular Symposium, Intracranial Stent Meeting (ICS) 2015 being held on the Gold Coast, Queensland, Australia.

This conference will bring together PhD and MD experts from their respective fields to meet and present their work. Both undergraduate and post-graduate students will also present their research work. This will hence provide ample opportunities to network and exchange ideas.

ICS2015 will address issues concerning the understanding of cerebrovascular disease and its treatment. There will also be a significant focus on topics including the challenges of implementing flow diverter (FD) technology; new designs and proposals, the development of new material research; including nano technology and endovascular devices, computational fluid dynamic research, and software regulatory studies.

We would like to thank our invited guest speakers, authors and presenters for sharing their expertise and research results.

And of course we are most grateful to our generous sponsors and supporters.

We trust you will enjoy your time at ICS2015 and the beautiful Gold Coast.

Regards
