The Figulla Flex II device Carlos AC Pedra, MD, PhD, FSCAI Flex II background • The Flex II (ASD and PFO devices) represent the third generation of Occlutech ASD and PFO occluders following the Figulla N (CE marked in May 2007) and the Flex I device. • 20000 implants have been performed worldwide with the Figulla family of ASD and PFO occluders. CONFIDENTIAL - © Occlutech 2012. All rights reserved. www.occlutech.com 2 Figulla N and I Experience at IDPC and HCor • 127 ASDs and 27 PFOs • 1 embolization/1 mal position: retrieval • No erosion • 2 residual leaks (additional small defects) Pedra CAC, Braga SLN, Pedra SRFF, Costa RN, Braga SLN, Esteves CA, Fontes VF.

All rights reserved. www.occlutech.com 37 Occlutech erosion statistics • With twenty thousand implants the real incidence ‘should be’ 40 cases of erosions • The reported number of erosions of the Figulla ASD/PFO occluders is ZERO. As a European manufacturer following CE/ISO rules, there is a complaint reporting system in place. CONFIDENTIAL - © Occlutech 2012. All rights reserved. www.occlutech.com 38 Ways to further investigate these data • Due to the rarity of erosion, it may not be feasible to do a randomized trial. Also difficult with registries. • An independent third party could audit operators/hospitals and gather the data. • The company could also initiate a registry for ASD implants with deficient rims.
