This book was released on 2018 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The implantation of a Left Ventricular Assist Device (LVAD) is a rapidly growing means of treatment for a large variety of heart ailments. These blood pumps necessarily exert some degree of shear stress on blood passing through them, which, over time, may cause the rupture of red blood cells, coagulation, thromboses, and bleeding. This limits their use as long term treatment and therapy. While the relationship of fluid shear to blood damage has been demonstrated previously, there is significant variance in the reported levels of damage. Were these stresses and subsequent damage to be well understood and related, existing and future VADs, as well as other blood contacting devices, could be more quantitatively designed to apply shear stresses below some damage threshold, thus allowing for longer effective treatment for an implanted patient. The aim of this thesis has been to construct a robust, Couette-flow shearing device in order to expose blood to a known shear stress under well controlled experimental conditions and to evaluate the subsequent damage. This shearing device has been constructed from an existing axial flow LVAD design that uses a novel magnetic bearing system to levitate the pump’s rotor. This technology gives the shearing device a uniquely simplified flow path and avoids any stresses contributed by conventional bearings. Both ovine and porcine blood has been investigated in the course of this work over a stress range of 0-350Pa and exposure time ranging from 200-1200ms. Extremely low levels of damage relative to studies in the literature were observed below 200Pa for both species over any exposure time. Above those conditions, porcine blood shows signs of higher fragility than ovine, seeing as much as 1% red blood cell damage within the investigated range, while ovine damage under identical conditions remained below 0.2%."--Abstract.

Download or read book Handbook of Hemorheology and Hemodynamics written by O.K. Baskurt and published by IOS Press. This book was released on 2007-10-03 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication primarily focuses on the macro- and micro-rheological behavior of blood and its formed elements, on interactions between the formed elements and blood vessel walls, and on the microvascular aspects of hemodynamics. Since many aspects of hemorheology and hemodynamics are affected by disease or clinical states, these effects are discussed as are hyperviscosity syndromes, therapy for disturbed blood rheology, and methods in hemorheology and hemodynamics. Sections of the Handbook include History of Hemorheology; Hemorheology, covering basic aspects, blood composition, blood rheology, cell mechanics, pathophysiology, methods and comparative studies; Hemodynamics, covering basic principles, microcirculation, in vivo effects, endothelium and methods; and Clinical Aspects of Hemorheology, covering hyperviscosity, clinical significance and treatment. The goal is to foster greater interchange between workers in the fields so as to promote collaborative efforts and, hopefully, improved health. In selecting topics for this handbook the editors have attempted to provide a general overview of both basic science and clinical hemorheology and hemodynamics. Hemorheology and hemodynamics are closely related, the former dealing with all aspects of the flow and interactions of the individual blood cells mostly studied in vitro, the latter with the in vivo relationships among vessel architecture, driving pressure, flow rate and shear stress. The linkage between the in vitro and in vivo research described in the book will be of interest to both basic science and clinical investigators. The editors of the handbook have each been active in the fields of bio- and hemorheology for many years, and have published extensively. They have successfully achieved their objective to publish a well-written and well-edited handbook that will be valuable for researchers and students in the field.
Download or read book Biological Performance of Materials written by Jonathan Black and published by CRC Press. This book was released on 2005-12-20 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioengineers need a thorough grounding in biocompatibility - the biological performance of materials. Until now, there were no publications suitable for a neophyte in the field; prior publications were either not comprehensive or focused on rather narrow interests. Drawing on the author's 35 years of experience as a teacher, researcher, and consultant in biomaterials science and engineering (BSE), Biological Performance of Materials: Fundamentals of Biocompatibility, Fourth Edition focuses primarily on principles of biological performance at a relatively fundamental level, analyzing interactions between living organisms and nonliving materials used in medical devices - the subject that sets BSE apart as a distinct field of investigation. Following an introductory section, the book is divided into three sections: the material response to biological systems, host response to biomaterials, and test methods for determining biological response in vitro as well as in animal models and clinical settings. Supplemental "Interparts" summarize the physical properties of commonly used metallic, polymeric, and ceramic biomaterials. They also provide a guide to understanding the clinical performance of implanted biomaterials.

Available in PDF, EPUB and Kindle. Book excerpt: J. Navratil The performance of operations on the heart and its replacement by a trans planted or artificial heart has been an age old dream of man. Rehn for example in an early attempt, in 1868 performed a closure of a heart wound after a thoracic puncture. At that time noone thought that this attempt was the beginning of cardiac surgery. The dream was partially realized when the replacement of the heart function by the heart-lungmachine became possible. Immediately following the first operations, cardiac surgeons and cardiologists saw with great enthusiasm that this machine could be an important tool for correcting congenital and non congenital heart diseases. However, the heart-lungmachine was soon seen to not be an optimal instrument for controlling cardiac failure after cardiopulmonary bypass or myocardial infarction. then arose for the development of mechanical assistance to the heart. Concepts The rollerpump was first designed for assisted circulation and could be applied clinically in 1962. A new concept of mechanical assistance to the heart was pro vided by the intra aortic balloon pump and later by the bypass ventricles. Use of the intra aortic balloon pump can reduce cardiac work by counterpulsation in accord with the natural ECG. The bypass ventricle can functionally replace the heart in series or parallel to the natural heart. The intra aortic balloon pump, now an established method, has reduced the number of patients who used to die from cardiac failure.
