In-vitro Assessments of Clot Elicitation by Thrombogenic Fibers vs. Embolization Coils.

Late and persistent type II endoleaks (EL2) following Endovascular Aneurysm Repair (EVAR) have been recognized as an independent and significant risk factor for aneurysm sac growth and secondary procedures. Solutions are available for treatment, with varying success rates; preventive perioperative sac embolization with coils appears safe and effective. The objective of this study is to compare whole blood coagulation elicited by a textile stent-graft equipped with thrombogenic, patented "Kardiozis" fibers (PKF) to that elicited by embolization coils in an in vitro study.

Deformability- and size-based microcapsule sorting.

Biomedical applications often require to sort cells according to their physical properties, such as size, density or deformability. In recent years, microfluidics has provided a variety of tools to sort micro-objects. We present here a simple microfluidic device consisting of a channel containing a semi-cylindrical obstacle against which capsules are squeezed by the flow, followed by a diverging chamber where streamlines separate.
