  1. 1. Designing a bioreactor to test mechanical properties of decellularized heart valves

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Viktor Börjesson; Oskar Gögelein; [2023]
    Keywords : Technology and Engineering;

    Abstract : Aortic valvular disease is a severe ailment that causes great suffering and many deaths worldwide. The exponentially increasing prevalence of the disease has accelerated the demand of a new functioning valve prosthesis. A new approach is to decellularize homograft heart valves, which has demonstrated promising results in clinical trials. READ MORE

  3. 2. Concept Design and Prototyping of a Test Rig for In Vitro Hemolysis Assessment of Pulsatile Blood Pumps : A design with an Improved Blood Filling and De-airing Interface

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Yun-Ting Lee; [2022]
    Keywords : Hemolysis assessment; test rig design; mock loop; pulsatile flow blood pumps; blood filling and de-airing processes; Hemolysbedömning; testriggdesign; mock loop; pulserande blodpumpar; blodfyllning och avluftningsprocesser;

    Abstract : Hemolysis assessment of heart pumps is necessary to be carried out before progressing to clinical trials. Blood pump hemolysis assessment standards, such as ASTM F1830 and F1841, were initially based on continuous flow pumps and included the pulsatile flow pumps later in 2019. READ MORE

  4. 3. Ultrasound Imaging Velocimetry using Polyvinyl Alcohol Shelled Microbubbles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ida Johansson; [2022]
    Keywords : Ultrasound imaging velocimetry; ultrasound contrast agents; polyvinyl alcohol; microbubbles; echo particle image velocimetry; Ultrasound imaging velocimetry; ultraljudskontrastmedel; polyvinylalkohol; mikrobubblor; echo particle image velocimetry;

    Abstract : Current research within the field of ultrasound contrast agents (UCAs) aims at developing capsules which are not only acoustically active, but also have a chemically modifiable surface. This enables use in new areas, including targeted drug delivery and theranostics. READ MORE

  5. 4. Simulated cerebrospinal fluid motion due to pulsatile arterial flow : Master Thesis Project

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jesper Hägglund; [2021]
    Keywords : Computational fluid dynamics; Fluid structure interaction; Pulsatile flow;

    Abstract : All organs, including the brain, need a pathway to remove neurotoxic extracellular proteins. In the brain this is called the glymphatic system. The glymphatic system works by exchanging proteins from interstitial fluids to cerebrospinal fluids. The extracellular proteins are then removed through the cerebrospinal fluid drains. READ MORE

  6. 5. Development of Vessel Phantoms for Ultrasound Methods

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Benjamin Meirza; [2018]
    Keywords : Longitudinal movement of the arterial wall; Vasa vasourom; Micro vessles; SEBS; Ultrasound phantom.; Technology and Engineering;

    Abstract : Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation.
