Until recently, most artificial hearts have served as research tools to acquire further knowledge necessary ultimately to design practical systems for human use. Transcutaneous systems or percutaneous systems utilizing permanently implanted energy converters, batteries, and electronics packages have a number of substantial problems that would not exist if most system elements were kept outside the body. These problems include physiologic control, fit and fixation, foreign body infection, hermetic sealing, cable insulation and fatigue, inherent system complexity, stringent requirements for maintenance-free operation with long-term high reliability, and high cost. Percutaneous systems, particularly those in which only the blood pump is implanted, are an attractive choice for practical systems in the near future. A wearable, battery-powered electropneumatic total heart system should be developed.
直到最近，大多数人工心脏都用作研究工具，以获取最终设计供人类使用的实用系统所需的更多知识。利用永久植入的能量转换器、电池和电子组件的经皮系统或经皮穿刺系统存在许多重大问题，如果大多数系统元件置于体外，这些问题将不存在。这些问题包括生理控制、贴合与固定、异物感染、密封、电缆绝缘与疲劳、系统固有复杂性、对长期高可靠性免维护运行的严格要求以及高成本。经皮穿刺系统，尤其是仅植入血泵的那些系统，是近期实用系统的一个有吸引力的选择。应开发一种可穿戴的、由电池供电的电动气动全人工心脏系统。
