Structured PICO

Intervention

Artificial cardiac system designed as a V=N/D density wave closed-loop engine (including spiral KOKU scaffold, self-propagating density wave generation, and autonomous V=N/D ratio regulation)

Comparator

Existing artificial heart systems (VADs, total artificial hearts) designed as pumps

Presents a conceptual patent framework for a novel artificial heart design based on density wave mechanics rather than traditional pump action.

Limitations

Quantitative parameters remain sealed under KHDS v1.0.

Abstract

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.
