Abstract: [Problem] To perform interpretation assistance of a back portion image in real time using a general-purpose computer for any case of scoliosis. [Solution] An interpretation assistance apparatus includes a center line creating unit that creates a center line C in a back portion image of a subject, a measurement interval designating unit that accepts designation of an arbitrary measurement interval I along the center line C, a measurement width designating unit that accepts designation of an arbitrary measurement width W toward intersecting directions of the center line C, and a measurement point coordinate obtaining unit that obtains depth coordinates of respective measurement points that are apart from the center line on both the right and left sides by the measurement width W at every measurement interval I.

Abstract: [Problem to be Solved] Provided is a motile cell sorting device that can effectively sort motile cells, such as sperms, having excellent motility and morphology by performing image analysis when animal cells are sorted. [Means for Solution] The motile cell sorting device 1 comprises a storage unit 3, a first introduction unit (cell injection channel) 5, a first introduction control unit 7, a first holding unit (cell capture area) 9, a first derivation unit (cell collection channel) 11, a first derivation control unit 13, a collection unit (liquid storage) 15, a photographing unit 17, and a first controller 19.

Abstract: [Problem to be solved] To provide a stent graft wherein interference between a stent row and a branch stent graft has been suppressed. [Solution] This stent graft comprises a stent including a plurality of stent rows and a graft that makes contact with the stent, the stent graft having, in a section of the graft, a fenestration part facilitating the insertion of a branch stent graft, which is another stent graft.

Abstract: The purpose of the present invention is to provide an implement for positioning electrocardiographic measurement electrodes, with which it is possible to rapidly determine electrocardiographic electrode positions customized for individual patients. This implement (1) is for positioning electrocardiographic measurement electrodes, and has a plurality of holes (3, 5, 7, 9, 11, 13) corresponding to the positions of chest electrodes. The implement (1) preferably has a transparent front body section (19). The front body section (19) preferably has a plurality of cut-out holes (45). The implement (1) may have cut-out parts (47) that connect the plurality of holes.

Abstract: A training kit is provided for practicing aortic valve reconstruction. The aortic valve reconstruction training kit is provided with a blood vessel model and multiple valve leaflet models, and the blood vessel model has a base-capped or base-uncapped cylindrical form having an opening formed on at least the top part thereof. The blood vessel model also has a valve ring part which is formed in the middle of the cylinder and to which the valve leaflet models can be sutured. By using the training kit, it becomes possible to practice a suturing technique that is believed to be the most difficult in aortic valve reconstruction, namely, a technique of accurately suturing a new valve leaflet to a valve ring part, to which an abnormal valve leaflet has been attached, of a cylindrical aorta while viewing the inside of the aorta from above.

Abstract: To provide a valve cusp sizer which is small and easy to handle. The present invention relates to a valve cusp sizer 100 for determining the size of a valve cusp depending on the size of a cardiac valve. The valve cusp sizer 100 includes a front surface 10 formed in an arcuate surface form to be abutted against an organism, a back surface 20 positioned on an opposite surface side of the front surface 10, and a pinching portion 30 protruding from the back surface 20. By removing a grip member and a grip member attachment portion from a conventional valve cusp sizer in this manner, and by forming the pinching portion 30 to be held by a clamp, tweezers, or the like, it is possible to dramatically miniaturize the valve cusp sizer while maintaining necessary functions of the valve cusp sizer.

Abstract: A template 13 comprises a cusp base forming part 11 having a shape corresponding to a cusp base is provided to obtain cusp material for dispersing stresses exerted on the cusp. Such a cusp forming template may further comprise wing forming parts 15 corresponding to wing parts provided outside the cusp base forming part 11. As examples of the wing forming part, there may be employed a single or plural holes provided at a part or parts corresponding to the outline of each wing, and guide parts provided at parts corresponding to the outline of wings.

Abstract: In a case of repairing an aortic valve by forming a valve cusp with a biomembrane, the shape and the size of a valve cusp can be determined easily. An instrument including a valve cusp sizer for measuring the size of the valve cusp and a template for scribing lines for the shape of a valve cusp conforming to the measured size of the valve cusp, in which the valve cusp sizer has a plurality of differently-sized sizer blocks attached to each of the top ends of grip members respectively and each sizer block has an arcuate surface formed by cutting each of differently-sized circular cylinders at an angle conforming to the central angle for the commissure portions and, the template is formed with a scribing portion including a substantially semi-circular valve cusp base forming portion.
