Abstract: A prosthetic heart valve includes a prosthetic valve annulus and at least one prosthetic valve leaflet member including at least one coaptation surface configured for cooperating with at least one corresponding coaptation surface of the prosthetic heart valve. At least one valve leaflet member is displaceable by blood flow between a closed position and an open position to produce, correspondingly, a contact and a separation of cooperating coaptation surfaces. In the open position the separation of the cooperating coaptation surfaces enables the blood flow through the orifice in a first direction, and in the closed position the contact of the cooperating coaptation surfaces prevents the blood flow through the orifice in a second direction, opposite to the first direction.

Abstract: A method of estimating exercise capacity of a subject is disclosed. The method uses output radiofrequency signals transmitted to the subject during exercise and input radiofrequency signals received from the subject during exercise. The method comprises: determining a phase shift of the input radiofrequency signals relative to the output radiofrequency signals; calculating cardiac output based on the phase shift; and using the cardiac output for estimating the exercise capacity of the subject.

Abstract: A method of processing a signal pertaining to at least one electrical property of an organ of a subject is disclosed. The method comprises determining a physiological condition of the subject, selecting a frequency band, filtering the signal according to the frequency band, and dynamically adapting the frequency band in response to a change in the physiological condition.

Abstract: A method of monitoring sleep of a sleeping subject is disclosed. The method comprises determining a phase shift of input radiofrequency signals received from the subject during sleep relative to output radiofrequency signals transmitted to the subject during sleep, calculating cardiac output based on the phase shift, and using the cardiac output for identifying sleep apnea events.
