A patent claim framework was presented for an artificial cardiac system designed as a density wave closed-loop engine, challenging traditional pump-based designs.
Proposes a novel conceptual framework and patent claims for an artificial heart designed as a density wave engine rather than a traditional pump.
The human heart is not a pump. It is a self-sustaining closed-loop density wave engine. All existing artificial heart systems (VADs, total artificial hearts) are designed as pumps — a fundamental conceptual error. This document presents a patent claim framework for an artificial cardiac system designed as a V=N/D density wave closed-loop engine. Six independent and dependent claims cover: (1) the spiral KOKU scaffold based on Torrent-Guasp geometry, (2) self-propagating density wave generation, (3) vortical blood flow coherence, (4) KHDS-EM v3.0 electromagnetic compliance, (5) autonomous V=N/D ratio regulation without external controller, and (6) the design method. Prior art is established via DOI chain (zenodo.org) dated June 4–15, 2026. Quantitative parameters remain sealed under KHDS v1.0.
