  • Patent number: 11979986
    Abstract: A component-embedded substrate includes: a plurality of insulating layers each including a wiring pattern formed on one surface; an embedded component including a connection terminal; and a plurality of vias that electrically connect the connection terminal to the wiring patterns adjacent to each other in a lamination direction. The plurality of insulating layers is laminated on the connection terminal. Each of the plurality of vias is composed of a via hole formed in the respective insulating layer of the plurality of the insulating layers and a conductive material provided in the via hole. One of the plurality of vias is a connection via directly connected to the connection terminal. Another of the plurality of vias is a first adjacent via adjacent to the connection via in the lamination direction. The first adjacent via is connected to the wiring pattern formed on a surface of a top insulating layer.

  • Publication number: 20240085306
    Abstract: The present invention provides a novel method which makes it possible to obtain, from a piece of tissue, a sample enriched with cells or cell nuclei of interest. A piece of tissue is subjected to pretreatment comprising water flow disruption and/or ultrasonic disruption to obtain a population of particles including individually separated cells or cell nuclei. A population of particles significantly abundant in cells or cell nuclei of interest is sorted or fractionated on the basis of optical properties of the cell nuclei in the separated cells or of the separated cell nuclei or on the basis of physical properties of the cell nuclei in the separated cells or of the separated cell nuclei.

  • Patent number: 11304726
    Abstract: A tissue-fastening tool indwelling system includes: a sheath; a needle tube disposed in the sheath; a tissue-fastening tool including a wire having a coil region disposable in the needle tube in a stretched state and restorable to a coil shape with the same winding diameter outside the needle tube; a stylet connected to the wire; and a manipulation part for manipulating the stylet to advance the wire and rotate the sheath in a first direction. In a state where a distal end of the needle tube is proximal of the distal end of the sheath, the manipulation part is designed to operate such that the wire is delivered from the sheath by a length of one winding of the coil region per rotation of the sheath by less than one turn, and the protruding coil region biased to have a diameter larger than the winding diameter.

  • Publication number: 20200405289
    Abstract: A needle holder for holding a curved needle to which a suture thread is connected. The needle holder includes a flexible tube; and a grasper provided at a distal end of the flexible tube. The grasper includes a first jaw having a groove, and a protrusion at a distal end portion of the first jaw; and a second jaw movably connected to the first jaw. The grasper can hold the curved needle between the second jaw and the protrusion of the first jaw, and can hold a part of the suture thread between a surface of the groove and the second jaw such that another part of the suture thread passes through a gap formed between another surface of the groove and the second jaw. The protrusion has a hook surface for hooking the suture thread extending outside the groove.
