  • Publication number: 20220343378
    Abstract: A quotation system receives shape data of an article configured from a plurality of elements from a client terminal and provides quotation information of the article. The system has a memory for storing basic shape data and related shape data different from the basic shape data, and storing basic attribute information associated with a basic element of the basic shape data. The system also has a computer that is configured to acquire the basic shape data and the related shape data, determine whether the relationship between the related shape data and the basic shape data satisfies a predetermined condition, associate related attribute information, including information common to the basic attribute information, and store the related attribute information, and prepare quotation information of an article corresponding to the related shape data on the basis of the related shape data and the related attribute information stored in the memory.

  • Publication number: 20200352759
    Abstract: The purpose of the present invention is to properly accommodate an expandable structure inside a sheath. This retrieval mechanism is designed to retrieve an expandable member (1) from within a blood vessel (V). The retrieval mechanism is provided with a sheath tube (4) and a retrieval member (3) for retrieving the expandable member into the sheath tube. The retrieval member has a retrieval assistance part (32) for assisting in retrieving the expandable member into the sheath tube. The retrieval assistance part can be accommodated in the sheath tube so as to cover the base part of the expandable member.

  • Publication number: 20200345474
    Abstract: Provided is a stent graft (1) comprising: a framework portion (B) having a ductal shape and which is expandable and contractable radially of the stent graft, and a membrane portion (GF) disposed along the framework portion. The membrane portion (GF) comprises a bent guide portion (RU) comprising a regular arrangement of textured structures formed radially of the stent graft. The bent guide portion is composed so as to have priority over other sections of the membrane portion in deforming when the stent graft bends.
