Surfaces contactable by a bulk liquid for use in particle isolation are described. The surfaces comprise a plurality of ribs spaced apart to capillarily retain a portion of the bulk liquid and particles of interest therebetween. Collectively, the portion of the bulk liquid retained by the plurality of ribs on the surface forms a liquid film. The one or more particles received within the space and enveloped by the liquid film may be protected from one or more forces exerted by a draining meniscus passing over the surface.

Devices and methods for separating particles from a liquid

Dual sensor system for continuous blood pressure monitoring during transcatheter heart valve therapies (TVT), such as transcatheter aortic valve replacement (TAVR) or transcatheter mitral valve replacement (TMVR), comprises a controller, a support guidewire for TVT containing a first Fabry-P&#xe9;rot (FP) optical pressure sensor near its distal end, and a pigtail catheter for delivery of contrast medium containing a second FP optical pressure sensor near its distal end. For example, for TAVR, the support guidewire is positioned to place the first optical pressure sensor within the left ventricle (LV) for monitoring LV pressure, the pigtail catheter is positioned in the aorta to place the second optical pressure sensor in the ascending aorta for direct measurement of pressure in the aorta, downstream of the aortic valve, enabling continuous monitoring of blood pressure at both sensor locations during TAVR. The controller may be configured to interface with standard patient monitoring systems.
