Accession No.: RE60O0142(U) This report supplies information and evaluation of Soviet developments and application in the area of alloplasty and alloplastic materials. The general field of biostimulation and bioelectric control as applied to various prosthetic devices are discussed, as well as the application from these areas to future developments, not only in various aspects of clinical medicine, but also in industrial, commercial, and training situations, as well as to certain areas of aerospace operations. iii AMD-CR-01-4-66 SUMMARYThe Soviets are gaining considerable experience in the broad field of alloplasty, as well as in the design, construction, and application of equipment for artificial circulation, oxygenation, hypothermia, and hemodialysis. In the latter areas they seem to be suffering from a lack of technical and professional competence, as well as from poor materials and construction technology.The Soviets have introduced two new designs for the construction of artificial heart valves, a teflon-flap type and a segmented spherical model, Both of these deserve long-term clinical evaluation.
