Bacteria-responsive multilayer coatings comprising polycationic nanospheres for bacteria biofilm prevention on urinary catheters
(2016-01-21)
Article
Accés obertThis work reports on the development of infection-preventive coatings on silicone urinary catheters that contain in their structure and release on demand antibacterial polycationic nanospheres. Polycationic aminocellulose ... -
Building an antifouling zwitterionic coating on urinary catheters using an enzymatically triggered bottom-up approach
(2014-06-23)
Article
Accés restringit per política de l'editorialCatheter associated urinary tract infections are common during hospitalization due to the formation of bacterial biofilms on the indwelling device. In this study, we report an innovative biotechnology-based approach for ... -
Catheter tip distensibility substantially influences the aspiration force of thrombectomy devices
(2021-01-01)
Article
Accés obertBackground A direct aspiration first pass thrombectomy (ADAPT) is a fast-growing technique for which a broad catalog of catheters that provide a wide range of aspiration forces can be used. We aimed to characterize different ... -
Enzyme multilayer coatings inhibit Pseudomonas aeruginosa biofilm formation on urinary catheters
(2015-01-15)
Article
Accés obertBacteria use a signaling mechanism called quorum sensing (QS) to form complex communities of surface-attached cells known as biofilms. This protective mode of growth allows them to resist antibiotic treatment and originates ... -
Quorum-quenching and matrix-degrading enzymes in multilayer coatings synergistically prevent bacterial biofilm formation on urinary catheters
(2015-12-02)
Article
Accés obertBacteria often colonize in-dwelling medical devices and grow as complex biofilm communities of cells embedded in a self-produced extracellular polymeric matrix, which increases their resistance to antibiotics and the host ... -
Remotely accessible demonstrator for dynamic characterization of pressure measurement catheters
(Universitat Politècnica de Catalunya, 2009-07)
Projecte/Treball Final de Carrera
Accés obertIn this project an experimental board for the characterization of a catheter for blood pressure measurement was designed and implemented. This system aims to simulate an invasive blood pressure measurement system studying ... -
Trackability of distal access catheters: An in vitro quantitative evaluation of navigation strategies
(2022-04-21)
Article
Accés obertBackground In mechanical thrombectomy (MT), distal access catheters (DACs) are tracked through the vascular anatomy to reach the occlusion site. The inability of DACs to reach the occlusion site has been reported as a ... -
Transmural versus non-transmural in situ electrical impedance spectrum for healthy, ischemic, and healed myocardium
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2004-08-31)
Article
Accés obertElectrical properties of myocardial tissue are anisotropic due to the complex structure of the myocardial fiber orientation and the distribution of gap junctions. For this reason, measured myocardial impedance may differ ...
