Medical valve apparatus
TL;DR: In this paper, a valve assembly consisting of a valve seat and a movable membrane is described, where the flexible membrane has a corolla-like shape at the time of a forward flow to allow a free flow of the fluid passing in the through holes.

TL;DR: LFES may improve muscle strength and blood supply, and could be recommended for the treatment of patients with severe CHF.

TL;DR: It is demonstrated that an improvement of exercise capacities can be achieved either by classical exercise training or by home-based electrical stimulation, and LFES should be considered as a valuable alternative to classical exerciseTraining in patients with CHF.

Microcirculation of the bulbar conjunctiva in the goat implanted with a total artificial heart: effects of pulsatile and nonpulsatile flow.

TL;DR: A new system to observe the microcirculation on the bulbar conjunctiva was developed using a digital high definition microscope, and it is thought that the basal and flow stimulated endothelium derived nitric oxide release in the microvessels decreased because of the disappearance of pulsatility and that the nitrics induced the constriction of arterioles after the flow pattern was changed to the nonpulsatile mode.

TL;DR: When the flow pattern was changed from pulsatile to nonpulsatile, the velocity of erythrocytes in many capillaries dropped and remained at a low level, and the number of perfused capillary decreased.
