Patent number: 5964725Abstract: A gas exchange apparatus for use as a artificial lung incorporates a hollow fiber module for bundling a plurality of thin-walled hollow silicone fibers. The fibers are wound in the form of a twilled pattern so as to form an internal perfusion passage and an external perfusion passage. A housing encloses the hollow fiber module. The housing incorporates a first inlet and outlet formed on the housing for communication of gas or liquid with the internal perfusion passage, and a second inlet and outlet formed for communication of gas or liquid with the external perfusion passage.Type: GrantFiled: April 23, 1997Date of Patent: October 12, 1999Assignee: Fuji Systems CorporationInventors: Koshiro Sato, Masanori Katayama

Patent number: 5669930Abstract: A stent for intracorporeal retention is inserted in a human body, for instance, inside an airway, esophagus, or bile duct, and used for preventing a bore of the internal organs described above from being occluded. With this stent, discharge from the airway does not easily adhere to, nor deposit on, the internal surface of the cylindrical body, so that the occlusion thereof can effectively be prevented and, at the same time, granulation does not easily occur and, for this reason, occlusion of the airway can be prevented, which insures a high degree of safety for a human body.Type: GrantFiled: November 20, 1995Date of Patent: September 23, 1997Assignee: Fuji Systems CorporationInventor: Akira Igarashi

Patent number: 4686124Abstract: A thermoplastic resin-silicone rubber composite shaped article comprising (a) a shaped article of a thermoplastic resin selected from the group consisting of soft vinyl chloride resins, olefin resins, urethane resins and styrene resins and (b) a cured layer of an addition polymerization type silicone rubber composition adhering to the one or both surfaces of the shaped article of a thermoplastic resin. To the surface of the above shaped article of a thermoplastic resin to which the above cured layer of an addition polymerization type silicone rubber composition does not adhere, there may adhere another cured layer of the above addition polymerization type silicone rubber composition. To either or both of these cured layers, there may further adhere a layer of the above thermoplastic resin, other thermoplastic resin, a silicone rubber, a silicone resin, glass, ceramics or a metal.Type: GrantFiled: November 29, 1984Date of Patent: August 11, 1987Assignees: Sumitomo Bakelite Company Ltd., Fuji Systems CorporationInventors: Masayuki Onohara, Kenji Kawai, Masaru Shibata, Akira Igarashi, Nobuhisa Kawaguchi
