Abstract: A ventricular pressure waveform estimation device includes a calculation unit. The calculation unit estimates a plurality of coefficients of a model equation that indicates a left ventricular pressure waveform or a right ventricular pressure waveform by using values of one or more parameters related to a heartbeat or an arterial pressure to estimate at least a part of the left ventricular pressure waveform or the right ventricular pressure waveform.

Abstract: A medical support system that supports intravascular treatment includes: a detection device inserted into a blood vessel and configured to be capable of detecting a state of a treatment target which is the blood vessel or an object attached to the blood vessel; and a control unit configured to select a treatment device or a treatment method, which is suitable for the state of the treatment target detected by the detection device.

Abstract: An arterial-pressure estimation apparatus includes a control unit configured to acquire sensor data indicating timings at which blood flows generated, for one heartbeat, at two or more locations of a blood vessel downstream of an aorta when the at two or more locations are compressed such that a location of the two or more locations that is further downstream of the aorta has a higher compression pressure than a location of the two more locations that is further upstream of the aorta, and estimate a temporal variation of an arterial pressure based on the acquired sensor data.
