A Variable Stiffness Catheter Controlled with an External Magnetic Field

Remote magnetic navigation of catheters is a technique used to perform radiofrequency ablation of heart tissue in order to treat cardiac arrhythmias. The flexible magnetic catheters used in this context are in some cases not sufficiently dexterous to navig ...

In Vitro and In Vivo Effectiveness of an Innovative Silver-Copper Nanoparticle Coating of Catheters To Prevent Methicillin-Resistant Staphylococcus aureus Infection

César Pulgarin, Juan Kiwi, Sami Rtimi, Myriam Koumba Sarah Ballo

In this study, silver/copper (Ag/Cu)-coated catheters were investigated for their efficacy in preventing methicillin-resistant Staphylococcus aureus (MRSA) infection in vitro and in vivo. Ag and Cu were sputtered (67/33% atomic ratio) on polyurethane cathe ...

Thin films for Healthcare Acquired Infections (HAIs) prevention

Sami Rtimi

This thesis addresses the preparation of antibacterial surfaces for hospital facilities taking biomedical thin polymer films, textiles and catheter as probes. Magnetron sputtering is used to apply the coatings leading to fast bacterial inactivation in the ...

Geometrical deployment for braided stent

Mohamed Farhat, Pierre Bouillot, Hasan Yilmaz

The prediction of flow diverter stent (FDS) implantation for the treatment of intracranial aneurysms (IAs) is being increasingly required for hemodynamic simulations and procedural planning. In this paper, a deployment model was developed based on geometri ...

Quasi-Instantaneous Bacterial Inactivation on Cu-Ag Nanoparticulate 3D Catheters in the Dark and Under Light: Mechanism and Dynamics

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines

The first evidence for Cu-Ag (50%/50%) nanoparticulate hybrid coatings is presented leading to a complete and almost instantaneous bacterial inactivation in the dark (

An Injectable and Drug-loaded Supramolecular Hydrogel for Local Catheter Injection into the Pig Heart

Maartje Martina Cornelia Bastings

Regeneration of lost myocardium is an important goal for future therapies because of the increasing occurrence of chronic ischemic heart failure and the limited access to donor hearts. An example of a treatment to recover the function of the heart consists ...

Ultrafast laser ablation for targeted atherosclerotic plaque removal

Demetri Psaltis, Donald Benjaman Conkey, Thomas Jean Victor Marie Lanvin, Laurent Descloux

Coronary artery disease, the main cause of heart disease, develops as immune cells and lipids accumulate into plaques within the coronary arterial wall. As a plaque grows, the tissue layer (fibrous cap) separating it from the blood flow becomes thinner and ...

How to prevent venous cannula orifice obstruction during extracorporeal circulation

Julien Favre

Venous cannula orifice obstruction is an underestimated problem during augmented cardiopulmonary bypass (CPB), which can potentially be reduced with redesigned, virtually wall-less cannula designs versus traditional percutaneous control venous cannulas. A ...

Dissecting abdominal aortic aneurysm in Ang II-infused mice: suprarenal branch ruptures and apparent luminal dilatation

Nikolaos Stergiopoulos, Jessica Sordet, Bram Trachet, Alessandra Piersigilli, Peter Modregger, Patrick Segers

Aims In this work, we provide novel insight into the morphology of dissecting abdominal aortic aneurysms in angiotensin II-infused mice. We demonstrate why they exhibit a large variation in shape and, unlike their human counterparts, are located suprarenal ...

Coating nanocarriers with hyaluronic acid facilitates intravitreal drug delivery for retinal gene therapy

Hendrik Georges Deschout

Retinal gene therapy could potentially affect the lives of millions of people suffering from blinding disorders. Yet, one of the major hurdles remains the delivery of therapeutic nucleic acids to the retinal target cells. Due to the different barriers that ...
