Patent number: 11717334Abstract: A radiofrequency guidewire includes a core wire configured to be coupled to a radiofrequency generator. The core wire includes a proximal end and a distal end with respect to the radiofrequency generator. A tip structure is coupled to the core wire proximate the distal end. The tip structure includes one or more edge surfaces. The one or more edge surfaces provide an area of reduced curvature radius on the tip structure. The area of reduced curvature radius generates a higher electric field than other areas of the tip structure during a delivery of radiofrequency energy on the tip structure. A method of ablating an occlusion utilizing the radiofrequency guidewire is also disclosed.Type: GrantFiled: February 18, 2016Date of Patent: August 8, 2023Assignee: ASAHI MEDICAL TECHNOLOGIES, INC.Inventors: Wayne Ogata, Xiang Ian Gu, Steven Meyer, Osamu Katoh

Publication number: 20210060293Abstract: A catheter includes a shaft having a first lumen inside thereof, an expansion/contraction portion that is disposed on a distal end portion of the shaft and is expandable and contractible in a radial direction, and an actuation portion that expands and contracts the expansion/contraction portion. The expansion/contraction portion has a fixed portion fixed to the shaft, a sliding portion capable of sliding in a longitudinal direction of the shaft on an outer peripheral face of the shaft, and a suspension portion extending in the longitudinal direction of the shaft that connects the fixed portion with the sliding portion. When the sliding portion is slid toward the fixed portion by the actuation portion, the suspension portion expands in a radial direction of the shaft.Type: ApplicationFiled: September 25, 2020Publication date: March 4, 2021Applicant: ASAHI INTECC CO., LTD.Inventors: Yukiko HASE, Osamu KATOH, Yoshiki KANEKO, Kazuya KUBO, Ryotaro KOJIMA, Maiko KATAOKA

Patent number: 10786656Abstract: Devices and methods for recanalization of occluded body vessels using novel guidewires. A novel double-sided guidewire comprises a cross-section tapering from a more rigid middle section towards more flexible head sections. A first head of the guidewire is inserted into the occluded body vessel in a retrograde direction to traverse an occlusion. The guidewire is further advanced in the retrograde direction such that the first head and a portion of the middle section are retrieved from the body, thereby positioning the remainder of the guidewire traversing the occlusion in an antegrade direction and allowing for over the wire recanalization techniques in the antegrade direction.Type: GrantFiled: February 14, 2011Date of Patent: September 29, 2020Assignee: ASAHI MEDICAL TECHNOLOGIES, INC.Inventors: Wayne Ogata, Osamu Katoh
