摘要： An information processing method for assisting a user to be capable of smoothly ascertaining necessary information. An information processing method causes a computer to execute processing for acquiring classification data in which pixels constituting biomedical image data indicating an internal structure of a living body are classified into a plurality of regions including a living tissue region in which a luminal region exists, the luminal region, and an extraluminal region outside the living tissue region, and generating region contour data, in which a portion where a thickness from an inner surface of the living tissue region facing the luminal region exceeds a predetermined threshold is removed from the living tissue region, based on the classification data.

摘要： An adhesion promotion device is disclosed, which is capable of reducing risk factors of an anastomotic leakage after surgery. The adhesion promotion device has a main body portion disposed between biological organs serving as a joint object. The main body portion has a first region and a second region formed along an outer edge of the first region. The second region includes an adhesion promotion portion that promotes adhesion of a biological tissue. The first region includes a holding portion having a holding force with respect to the biological tissue which is stronger than that of the adhesion promotion portion.

摘要： An oxygen measurement device constituting an oxygen measurement system includes a urethral catheter and an oxygen sensor main body. The urethral catheter has a shaft in which a urethral catheter lumen that enables circulation of urine flowed in via a urethral catheter port from inside a bladder is formed; and has a hub in which a urine lumen that is provided at a proximal end of the shaft and communicates with the urethral catheter lumen is formed. The oxygen sensor main body is provided on the hub in a manner capable of being brought into contact with urine circulating in the urine lumen, and detects oxygen in the urine.
