Abstract: Biochemical markers that can be measured to determine the level of mechanical activation of a population of platelets are provided, and their use to prepare molecular signatures thereof are provided. The markers include phosphatidylserine, thrombin, integrin GPIIb/IIIa activation, glycoprotein GP Ib, P-selectin; platelet size; microparticle generation, or lipidomic profile of the membrane. The disclosed markers, measurement thereof, and signatures composed therefrom can be used in a variety of methods of patient selection, treatment monitoring, treatment selection, including both devices and active agents, and methods of treating subjects in need thereof, particularly humans.

Abstract: A polymeric valve which may include a heart valve, and also may include a trileaflet heart valve includes a stent having a base and a plurality of outwardly extending posts from the base and equidistant from each other. A plurality of leaflets each connected to a corresponding one of the posts at one end, and each of the leaflets connected to the base. Each of the leaflets having an operative end opposite the end connected to the post, and the operative ends of the leaflets being biased in a closed position such that the operative ends abut each other. The operative ends are configured to rhythmically open and close in relation to each other, and the leaflets include multiple cross sectional thicknesses at different portions of the leaflets.

Abstract: Provided herein is technology relating to microfluidic devices and particularly, but not exclusively, to devices, methods, systems, and kits for imparting stresses on a fluid flowing through a microfluidic device that is designed to mimic a stress profile of a macrofluidic device or pathology.
