Abstract: An image processing apparatus is described herein including an image input unit that receives an input of a tomographic image of a heart imaged from outside a body; a low motion site estimation unit that estimates a low motion site of the heart on the basis of the tomographic image; an infarct site estimation unit that estimates an infarct site of the heart; and a target site identification unit that identifies a site other than the infarct site among the low motion sites, as a target site.

Abstract: A spacer and implant assembly are disclosed, the spacer including an outer balloon that is folded so as to be dilatable, and an inner balloon that is folded so as to be dilatable, and that is removably inserted into the outer balloon. The inner balloon dilates in response to introduction of a dilating fluid having a lower viscosity than a viscosity of a filling material inserted into the outer balloon, and the outer balloon dilates in response to the dilation of the inner balloon.

Abstract: The medical device disclosed here is configured to remove a plurality of objects at a time from an interior of a living body by restricting the objects from dropping out from an interior of a basket and is capable of treating objects in a body tissues having different structures efficiently with the same device. A treatment portion of a medical device includes an outer basket and an inner basket. A plurality of outer leg portions of the outer basket and a plurality of inner leg portions of the inner basket are arranged so as to be staggered in a circumferential direction. The medical device may be used by being switched between a mode of using only the outer basket and a mode of using both of the outer basket and the inner basket.

Abstract: There is provided a tracheal tube that allows improvement in safety. The tracheal tube includes a tube main body, and a cuff that is mounted to the tube main body and has a barrel portion capable of being deflated and inflated. A covering region that covers a tracheal inner wall of a trachea in a state in which the barrel portion is inflated in the trachea has a sealing part that gets contact with the tracheal inner wall seamlessly in a circumferential direction of the barrel portion. The width of at least part of the sealing part is smaller than 1 mm.

Abstract: An expanding device for expanding the spacing between bones is provided. The expanding device includes a spacer configured to be expandable and disposed between the bones, a catheter provided with the spacer at a distal end thereof and adapted to introduce a filler into the spacer, and a sheath having a lumen through which the catheter is inserted and in which the spacer before expansion can be housed.
