Abstract

Artificial lung (AL) membranes are used for blood oxygenation for patients undergoing open-heart surgery or acute lung failures. Current AL technology employs polypropylene and polymethylpentene membranes. Although effective, these membranes suffer from low biocompatibility, leading to undesired blood coagulation and hemolysis over a long term. In this work, we propose a new generation of AL membranes based on amphiphobic fluoropolymers. We employed poly(vinylidene- co -hexafluoropropylene), or PVDF- co -HFP, to fabricate macrovoid-free membranes with an optimal pore size range of 30–50 nm. The phase inversion behavior of PVDF- co -HFP was investigated in detail for structural optimization. To improve the wetting stability of the membranes, the fabricated membranes were coated using Hyflon AD60X, a type of fluoropolymer with an extremely low surface energy. Hyflon-coated materials displayed very low protein adsorption and a high contact angle for both water and blood. In the hydrophobic spectrum, the data showed an inverse relationship between the surface free energy and protein adsorption, suggesting an appropriate direction with respect to biocompatibility for AL research. The blood oxygenation performance was assessed using animal sheep blood, and the fabricated fluoropolymer membranes showed competitive performance to that of commercial polyolefin membranes without any detectable hemolysis. The data also confirmed that the bottleneck in the blood oxygenation performance was not the membrane permeance but rather the rate of mass transfer in the blood phase, highlighting the importance of efficient module design.

  • In medical devices, fluoropolymer-based structures offer a superior and safer alternative to devices made from other types of polymers; polypropylene and polymethylpentene artificial lung membranes often exhibit inadequate biocompatibility, causing unwanted blood clotting and long-term hemolysis, whereas a novel fluoropolymer-based membrane has demonstrated optimal performance with no detectable

    “For example, in the field of medical devices, fluoropolymer-based structures offer a superior and safer alternative to devices made from other types of polymers; when polypropylene and polymethylpentene are used to make artificial lung membranes for blood oxygenation during open-heart surgery or acute lung failure, they often exhibit inadequate biocompatibility, resulting in unwanted blood”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
