AVAILABLE SPACE FOR A TOTALLY IMPLANTABLE CARDIAC PROSTHESIS

摘要

The goal of the present program is to define the spatial constraints of the body for a totally implantable cardiac prosthesis. The design is such that the prosthesis is compatible with both the human experimental animal, the calf Most recent efforts were directed to and shape of the human thorax for implanting the blood pump. T done by formulating a mathematical shape model from dimensions obtained from plastic molds made in the chest cavity of human cadavers. The shape model is used in conjunction with dimensions obtained from chest radiographs of living humans to arrive at a statistical distribution of chest dimensions. At present the shape model, being developed by computer. is nearly complete and over one-third of the radiographic data has been obtained.
