Patent number: 11123528Abstract: A balloon catheter includes a shaft and a balloon having one or more fold lines. The balloon is disposed outside the shaft, and the balloon includes one or more first regions and one or more second regions. The first region retains medicine on an outer surface of the balloon. The second region retains less medicine than the first region or retains no medicine.Type: GrantFiled: January 4, 2019Date of Patent: September 21, 2021Assignee: KANEKA CORPORATIONInventors: Soichiro Kita, Masao Sato, Hitoshi Tahara, Ryoji Nakano, Motokazu Watanabe, Takuji Nishide

Patent number: 10967157Abstract: A balloon catheter includes a shaft, and a balloon provided outside the shaft. A drug is provided on an outer surface of the balloon, and the balloon has at least a straight tube part. A change ratio of an outer diameter of the straight tube part, (D28?D24)/D24, is 1.1% or less. D24 is the outer diameter of the straight tube part when an internal pressure of 2.43 MPa (24 atm) is applied, and D28 is the outer diameter of the straight tube part when an internal pressure of 2.84 MPa (28 atm) is applied.Type: GrantFiled: January 4, 2019Date of Patent: April 6, 2021Assignee: KANEKA CORPORATIONInventors: Masao Sato, Soichiro Kita, Hitoshi Tahara, Ryoji Nakano, Motokazu Watanabe, Takuji Nishide

Patent number: 9011745Abstract: It is an object to stably provide a thin-walled flexible medical tube having excellent kink resistance and tensile strength by a simple manufacturing method. The object is achieved by a method for manufacturing a medical tube that includes a coil layer on an inside of an outer layer tube made of a resin, and the method includes inserting the coil layer into the outer layer tube and heating the outer layer tube at a molding temperature lower than a melting point of the outer layer tube, thereby bringing the outer layer tube into contact with the coil layer to slidably fix the outer layer tube onto the coil layer.Type: GrantFiled: June 7, 2011Date of Patent: April 21, 2015Assignee: Kaneka CorporationInventors: Hitoshi Tahara, Akitoshi Sakata

Publication number: 20110058594Abstract: In power line communication using a power line as a transmission path, a transmitter terminal transmits a communication signal while changing a phase parameter of the communication signal transmitted, in the continuous communication signal, according to an impedance variation amount on the transmission path. In this communication method, the communication signal is received stably with no variation in the phase parameter of the communication signal in response to the impedance variation amount on the transmission path, permitting high-speed data communication with reduced communication error.Type: ApplicationFiled: September 10, 2010Publication date: March 10, 2011Applicant: Panasonic CorporationInventors: Takayoshi KOYAMA, Yuichi Yamamoto, Hitoshi Tahara, Nobutaka Kodama

Publication number: 20050105639Abstract: The present invention relates to a method of wirelessly transmitting data having continuity, while maintaining its continuity, from a transmission apparatus to a reception apparatus in real time. One of the transmission and reception apparatuses in which a recovery from a transmission abnormality generated during data transmission is completed notifies the other apparatus of a recovery completion notice via packet communication. The other apparatus receives the recovery completion notice and implements a recovery operation to dissolve the transmission abnormality generated therein in synchronization with a recovery operation of the one of the apparatuses.Type: ApplicationFiled: November 10, 2004Publication date: May 19, 2005Inventors: Hitoshi Tahara, Yuichi Yamamoto
