TRANSCRIPT
New TAVR devices :
PVL en Pacemaker rate problems solved
Tailored patient treatment, with a valve choice best for different anatomical features.
Unresolved issue is durability.
Direct Flow Medical® Transcatheter Aortic Valve System
Designed to minimize AR and improve outcomes • Second generation design • Non-metallic, conformable • Polymer-filled double ring frame
Controlled procedure • Precise placement via 3 positioning wires • Assess hemodynamic function prior to
release • Fully repositionable and retrievable
Safe placement • Valve fully functional throughout procedure • No rapid pacing during valve release (stable

The Lotus™ Valve
Design Goals
Controlled mechanical expansion
Valve functions early in deployment to provide hemodynamic stability
Valve is fully repositionable & retrievable throughout the entire deployment process
Adaptive seal conforms to irregular anatomic surfaces to minimize paravalvular leak
Bovine Pericardium in Nitinol in Frame
Adaptive Seal Radiopaque Marker To aid precise positioning
