(A-B) the Coherex WaveCrest LAA occlusion system is the latest development in LAA occlusion devices. It consists of a nitinol frame with retractable coils and anchors to enable optimal device positioning. The device consists of a multi-composite membrane including a PTFE membrane on the LA side of the device, and a foam substrate on the LA-opposing surface to minimize residual leaks. Very recently, the WAVECREST I clinical trial was completed - CE Mark approval was obtained in September 2013. (C) a cine image showing contrast injection distally of the device (into the LAA) in order to assess complete LAA closure. (D) a TTE image confirming the device is well-seated and without leaks. Some images were presented by Franzen O. on EuroPCR 2013.⁴³
