Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to obtain feature values related to the shape and a property of the heart. The processing circuitry is configured to estimate, by using the feature values, a state of the heart after a chest is opened. The processing circuitry is configured to estimate, based on a result of the estimation of the state of the heart, a state of the heart after the chest is closed after a treatment is completed. The processing circuitry is configured to output a parameter related to the estimated state of the heart after the chest is closed to a display.

Abstract: An aspect of the present disclosure calculates a phase variance value indicating a degree of variance of a phase in a surrounding of each position in a biological tissue, based on phase values of excitation wave at respective positions in the biological tissue that acts in response to excitation caused by propagation of the excitation wave in the tissue, and generates an analysis map, based on a time series of at least part of the phase variance values at the respective positions. Since the phase variance value indicates the degree of variance of the phase in the surrounding, a position having a large degree of variance of the phase in the surrounding may be specified as a rotation center of rotating excitation wave.

Abstract: A tissue ligating device comprises a first fixation part to which a base end part of a suture thread is fixed and a second fixation part configured to allow insertion of the suture thread therethrough and allow to be crimped so as to newly fix a part of the suture thread, and thereby to define a loop starting from the base end part, in a state after ligation of tissue is performed. The second fixation part includes a back side wall part, a front side wall part, and a curved wall part turning back from the back side wall part to the front side wall part. An end part of the front side wall part far from the curved wall part is inclined or curved towards a front side.
