Synthetic heart

A Synthetic heart, classified within Vey’Zari medics as Core-Pulse Actuator Systems (CPAS), is a class of internal bio-mechanical pumps designed to replace the function of a biological heart in heavily augmented or non-viable circulatory systems. Developed originally for long-term use in cybernetic operatives whose organic hearts degraded under systemic augmentation stress, the CPAS unit uses a tri-chamber magnetic pulse driver array to maintain rhythmic circulatory compression across synthetic or hybrid vascular networks. Unlike organic hearts, which rely on electrochemical nerve impulses, the CPAS operates through neuro-linked impulse conversion—integrating directly into the user's spinal interfacing node and responding to dynamic bioelectric cues. The system requires synthetic or modified blood for optimal function, as unregulated clotting and ion incompatibility make it unsuitable for standard physiology.   Each CPAS module is constructed from heat-neutral alloys and non-reactive polymeric sheathes, featuring a self-lubricating inner lumen and a triple-redundant internal regulator that prevents arrhythmia, pressure spikes, or electromagnetic failure. The synthetic heart runs on a long-cycle microcellular power core embedded near the clavicular junction, capable of sustaining uninterrupted function for up to twelve years before requiring recalibration. Because of its complexity, full CPAS integration is typically performed only in high-clearance surgical sanctums under syndicate control, with extensive pre-conditioning required. The only known outlier to this protocol is Calyra Val’Druna, whose heart was replaced with a compact, pediatric-scaled CPAS unit at birth due to complete failure of natural cardiac function. The procedure, conducted in absolute secrecy, remains unrepeated and controversial, as full CPAS implantation in undeveloped bodies is considered medically unstable and ethically prohibited. While the technology is common among elite augmented operatives, it is never used as a life-saving measure for standard Vey’Zari births due to the strict compatibility and high-risk demands of the system.
