  • Patent number: 10980402
    Abstract: A treatment device includes a flexible sheath; a control wire that can move axially within the flexible sheath; a first treatment member connected to a distal end of the control wire; a second treatment member connected to a distal end of the first treatment member; and a protection member that covers the second treatment member depending on the mode of operation. When the treatment device is in a first treatment mode, the second treatment member projects from a distal end of the protection member. When the treatment device is in a second treatment mode, the first treatment member projects from the distal end of the flexible sheath, and the protection member covers the second treatment member.

  • Publication number: 20210093288
    Abstract: An apparatus for insertion into a body through a working channel of an endoscope includes a catheter including a dilator, a guide tube disposed in a lumen of the catheter, and a handle including a puncturing actuator operatively coupled to the proximal end of the guide tube. The dilator may be a cautery device and/or a balloon. The apparatus may also include a stylet needle that includes a cutting distal end for puncturing tissue and extends through a lumen in the guide tube. The handle may further include a stopper detachably coupled to the puncturing actuator to fix a position of the puncturing actuator on the handle, and moveable on the handle independently of the puncturing actuator when detached from the puncturing actuator. The disclosed embodiments also include a method for forming a passageway in a wall of a hollow body organ using the apparatus.

  • Publication number: 20180153536
    Abstract: A treatment instrument for an endoscope is equipped with a sheath; and a balloon which is provided at the sheath, the balloon being configured to be expandable to an unfolded inflated shape from a folded initial shape by supplying a fluid, the balloon having a first region and a second region provided at both end portions in a longitudinal direction, and an intermediate section provided between the first region and the second region. In the initial shape of the balloon, an amount of residual strain of the intermediate section is larger than the amount of residual strain of the first region and the amount of residual strain of the second region. When an internal pressure of the balloon has a first internal pressure value, the first region and the second region are unfolded to be faster than the intermediate section, thereby having a greater diameter than the intermediate section.

  • Publication number: 20170215491
    Abstract: A pad material includes a urethane material satisfying LC?1 and RC?80 where LC represents compression hardness and RC represents compression resilience. In a garment with cup sections in which a pad including the pad material is disposed at least in a lower cup section, it is possible to control clothing pressure applied to lower parts of a bust from the lower cup section and to reduce a total amount of the clothing pressure applied to the bust. Furthermore, flexibility, lightweightness, and fluffiness of the cup sections are enhanced and both shapeability of the bust and comfortability can be achieved.

  • Patent number: 9644293
    Abstract: A knitted fabric includes: a first knitted fabric region and a second knitted fabric region. The first region and the second region have different elongations from each other. The knitted fabric further includes buffer regions. The buffer regions are provided in at least one of the first region and the second region so as to be in contact with the first region and the second region. The buffer regions each have an elongation set so that, as the buffer region extends toward either one of the first region and the second region, the difference between the elongation of the buffer region and the elongation of the first region or the second region toward which the buffer region extends is reduced gradually. Between the first region and the second region, there is no boundary line that is substantially parallel to the course direction of the knitted fabric.

  • Patent number: 9011199
    Abstract: Provided is a women's garment with cup parts which make bust top positions look higher, while enabling breasts to appear larger in volume. A women's garment with cup parts has a pair of cup parts, each cup part having a first shaping region for covering a nipple and pressing a breast at the time of putting the cup part on the breast and a second shaping region, located lower than the first shaping region, for pressing the breast, the second shaping region having a volume larger than that of the first shaping region, the cup part having a top on a front face side residing within the first shaping region when seen from the front face side. While the second shaping region pushes the breast up, the first shaping region further presses the pushed-up breast, so the bust top positions look higher, while the breasts appear larger in volume.
