  2. 1. A minimally invasive axial blood flow pump : an experimental and clinical study

    Author : Urban Lönn; Howard Frazier; Linköpings universitet; []
    Keywords : Axial blood flow pump; Hemopump; LVAD; Beating heart CABG; MEDICINE; MEDICIN;

    Abstract : The first aim of this thesis was to evaluate a new minimally invasive axial blood flow pump for treatment of patients needing circulatory support after open heart surgery. This system, the Hemopump temporary cardiac assist device, is a very small catheter mounted intracorporeal pump, which is introduced transvalvularly into the left ventricle. READ MORE

  4. 2. Classical and Quantum Correlations in Microwave Frequency Combs

    Author : Shan Williams Jolin; David B. Haviland; Pertti Hakonen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Josephson junctions; parametric amplifiers; multipartite entanglement; microwaves; frequency comb; Gaussian states; bichromatic pump; surface acoustic waves; IQ mixer; fully inseparable states; superconducting circuits; hybrid circuits; intermodulation; nonlinear resonators; Material and Nano Physics; Material- och nanofysik;

    Abstract : Denna avhandling undersöker korrelationer i frekvensdomänen, av både klassiskt och kvantmekaniskt ursprung, i icke-linjära mikrovågskretsar. Syftet är att utveckla en kompakt metod för att generera kvantmekaniska korrelationer mellan harmoniska oscillatorer (s.k. READ MORE

  5. 3. Concept design and In Vitro evaluation of a novel dynamic displacement Ventricular Assist Device

    Author : Mattias Stenberg; Håkan Elmqvist; Ulf Kjellman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ventricular Assist Devices; artificial heart; heart failure; InVitro evaluation; Medical engineering; Medicinsk teknik;

    Abstract : Ventricular Assist Devices (VADs) are mechanical pumps used to off-load a deceased heart, primarily in late stage congestive heart failure patients. VAD employment may facilitate cardiac recovery, but most often provides time before a suitable heart transplant can be found. READ MORE

  6. 4. Bioelectronic Devices for Targeted Drug Delivery and Monitoring of Microbial Electrogenesis

    Author : Arghyamalya Roy; Daniel T Simon; Klas Tybrandt; Christopher Proctor; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrophoresis; Extracellular Electron Transfer EET ; Ion Exchange Membranes IEM ; Drug Delivery; Bupivacaine; Chronic Neuropathic Pain; Microfabrication; Inkjet Printing; Organic Electrochemical Transistor OECT ; Fumarate; Shewanella oneidensis; Dorsal Root Ganglia DRG ; Organic Electronic Ion Pump OEIP ;

    Abstract : Despite a range of pain therapies available in the market, 70% of patients report so-called “breakthrough pain”. Coupled with global issues like opioid crisis, there is a clear need for advanced therapies and technologies for pain management. READ MORE

  7. 5. Management of patients treated with left ventricular assist devices : A clinical and experimental study

    Author : Bengt Peterzén; Henrik Casimir-Ahn; Hans Ruthberg; Lars Wiklund; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postcardiotomy heart failure; perioperative monitoring; coronary artery bypass; heart-assist devices; heart failure; congestive; ventricular dysfunction; Thoracic surgery; Thoraxkirurgi;

    Abstract : This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. READ MORE
