Abstract: A balloon for a catheter includes an inflatable portion, a distal end connecting portion, and a proximal end connecting portion. The balloon for the catheter also includes an inner side thick film portion and a thin film portion having differing thicknesses from each other. The thickness of the inner side thick film portion is greater than the thickness of the thin film portion. An inner surface at the inner side thick film portion protrudes further toward an inner side than an inner surface at the thin film portion. An outer surface at the inner side thick film portion does not protrude further to an outer side in the radial direction than an outer surface at the thin film portion.

Abstract: A balloon catheter includes a catheter shaft, a balloon, and a protruding portion. The balloon is connected to the catheter shaft. The balloon includes an inflatable portion and a distal end connecting portion. The protruding portion protrudes radially outward with respect to a center axis of the catheter shaft. The protruding portion has at least one of a first protruding portion provided on the distal end connecting portion of the balloon, or a second protruding portion provided on a distal end extending portion. The distal end connecting portion includes at least a region where a protrusion amount is smaller than a protrusion amount of the protruding portion.

Abstract: A balloon has an inflatable portion that forms a tube shape extending in an extending direction in an inflated state, a distal end connecting portion provided to an end portion of the inflatable portion on one side thereof, and a proximal end connecting portion provided to an end portion of the inflatable portion on the other side thereof. At least the inflatable portion includes a plurality of first portions that forms wings in the deflated state and a plurality of second portions that is adjacent to the plurality of first portions in a circumferential direction centered on the center axis. In the process of changing shape from the inflated state to the deflated state, the plurality of second portions moves towards the center axis in advance of the plurality of first portions and thereby forms, in the inflatable portion, indentations recessed toward the center axis.

Abstract: A motor includes a shaft disposed along a central axis, a rotor fixed to the shaft and capable of rotating around the central axis, a stator outside of the rotor, a first housing including a cylindrical portion and disposed on an outside of the stator, and a second housing disposed on an upper side of the first housing. The second housing includes a top plate and projected portions extending downward and spaced apart. Ribs extending from both end portions of the projected portion in the circumferential direction to an inside in the radial direction as viewed in the axial direction are disposed on a lower surface of the top plate.

Abstract: A motor includes a rotor that includes a shaft disposed along a central axis extending vertically, a stator that faces the rotor in a radial direction, a bearing section that supports the rotor such that the rotor is rotatable with respect to the stator, and a bracket that holds the bearing section. The bracket includes a cylindrical bracket portion that is disposed outwardly of the bearing section in the radial direction, and a bracket bottom portion that includes a bracket opening portion. The bearing section includes a bearing that rotatably supports the shaft, and a plate portion disposed below the bearing and extending in a direction orthogonal to the central axis. At least a portion of the plate portion faces the bracket opening portion in an axial direction.
