The feasibility of fully implantable circulatory support systems depends on the ability of the body to dissipate heat from the power source driving the blood pump. If the energy source is a radioisotope, the body must also tolerate chronic intracorporeal radiation. The objective of the endogenous heat program is to characterize the effects and management of the added thermal load and nuclear radiation on mammals. This program is a continuation of initial canine studies using electrical heat exchangers and subsequent efforts utilizing 16- and 24-watt plutonium-238 heat sources. The effects of radiation equivalent sources in canines and primates have been under study for several years. The possibility of rejecting heat through the bladder of an axisymmetric blood pump has been evaluated. On the basis of the negative findings of this work, effort has recently been diverted to synthesizing a pump specifically to incorporate the heat rejection function. (GRA)
