Key result
Patent framework outlines a novel artificial cardiac system designed as a density wave closed-loop engine.
Why the study?
Existing artificial heart systems are designed as pumps, which is considered a conceptual error because the human heart is viewed as a self-sustaining closed-loop density wave engine.
Presents a conceptual patent framework for a novel artificial heart design based on density wave mechanics rather than traditional pump action.
Novel density-wave artificial heart concept remains untested; leaves open feasibility for clinical translation.
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.

Yoshimitsu Katayama (2026) studied Artificial heart system. Cardiac Density Wave Engine vs. Existing artificial heart systems (pumps) was evaluated. A patent claim framework was presented for an artificial cardiac system designed as a V=N/D density wave closed-loop engine, covering six claims including a spiral KOKU scaffold.
