Competing Interests

Remo Leber, Johann-Jakob Schmid, and Gianluca Generali are either part-time or full-time employees of SCHILLER AG, Baar, Switzerland. Ramun Schmid is employed by SCHILLER AG, Baar, Switzerland and is a teacher at Bern University of Applied Sciences. Dr. Roger Abächerli is a part-time employee of SCHILLER AG, Baar, Switzerland, and a teacher at Bern University of Applied Sciences. He is also a part-time scientific research associate at the Cardiovascular Research Institute Basel, Cardiology, University Hospital Basel, Switzerland. The presented filter is used in the R&D department for further investigation and may be used in clinical products. Further, a related patent application (PCT/EP2014/068534) has been made. Nevertheless, this does not alter the authors' adherence to PLOS ONE policies for sharing data and materials.
