Excerpt from Biomedical Engineering and Instrumentation Branch, Division of Research Services, National Institutes of Health: Annual Report Fy 1980Major Findings: A number of forms and compositions of embolizing agents implanted in cats and monkeys have proven to be unsatisfactory due to localized tissue reactivity.Tensile properties of selected polyurethanes can be significantly enhanced for implant use through a controlled annealing process.Perfusion of drugs through micro-catheters can be determined through a calibrated capillary as a function of viscosity and pressure.Significance: Physiologically compatible polymers with enduring strength are needed for such applications as heart valves, heart-assist devices, vascular implants, indwelling catheters, and subcutaneous uses.Preposed Cours Extend experimental studies to further characterize the surface and bulk properties of biomaterials and, more specifically, determine their interactions with blood and subcutaneous tissue to facilitate development of better surgical implants.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
