Patent number: 9833329Abstract: An implant assembly smoothly causes a folded implant to indwell a living body, and which can smoothly expand the implant without causing the implant to be displaced from a predetermined indwelling position when a filling material is injected. The implant assembly has the implant that is configured to be transformable from a folded and contracted state to an expanded state by the introduced filling material, and in which at least a portion of a surface thereof is covered with a covering material m whose friction coefficient increases by coming into contact with a body fluid, and guiding means for preventing the implant and the body fluid of the living body from coming into contact with each other inside the living body, and for guiding the implant to move to the indwelling position inside the living body.Type: GrantFiled: October 2, 2015Date of Patent: December 5, 2017Assignee: TERUMO KABUSHIKI KAISHAInventors: Yuji Nakagawa, Suguru Hata

Patent number: 9101418Abstract: A medical device includes a tubular body having a first lumen so designed as to receive a fluid from an opening at one end of the first lumen and discharge the fluid from an opening at the other end of the first lumen, and an expandable body attached to the tubular body. The first lumen communicates with the space inside the expandable body and the expandable body expands by the internal pressure of the fluid which is injected from the opening at one end and enters the space inside the expandable body through the first lumen.Type: GrantFiled: February 28, 2012Date of Patent: August 11, 2015Assignee: TERUMO KABUSHIKI KAISHAInventors: Yuichi Tada, Yuji Nakagawa, Suguru Hata, Yasushi Kinoshita

Patent number: 8436214Abstract: An object of the present invention is to provide (i) a novel non-crystalline form of 9,9-bis(4-(2-hydroxyethoxy) phenyl) fluorene, which non-crystalline form maintains quality at a certain level, and is excellent as a polymer material, and (ii) a method of preparing the non-crystalline form. According to the present invention, molten 9,9-bis(4-(2-hydroxyethoxy) phenyl) fluorene in a liquid form is cooled and therefore is solidified. With the method, it is possible to provide a novel non-crystalline form of 9,9-bis(4-(2-hydroxyethoxy) phenyl) fluorene which has a small risk that powder dust of 9,9-bis(4-(2-hydroxyethoxy) phenyl) fluorine might cause explosion or a health problem. Further, the non-crystalline form of 9,9-bis(4-(2-hydroxyethoxy) phenyl) fluorene can be adjusted arbitrarily in particle diameter by, for example, pulverizing the non-crystalline form in accordance with equipment or usage.Type: GrantFiled: June 1, 2010Date of Patent: May 7, 2013Assignee: Taoka Chemcial Co., Ltd.Inventors: Katsuhiro Fujii, Suguru Hata, Kohta Fukui
