Publication number: 20240082551Abstract: A catheter includes a hollow catheter shaft, and a distal tip connected to a distal end portion of the catheter shaft. A recess is formed in the distal end portion of the catheter shaft, and a proximal end portion of the distal tip is inserted into the recess. According to this catheter, joint strength of the distal tip and the catheter shaft can be enhanced.Type: ApplicationFiled: October 17, 2023Publication date: March 14, 2024Applicant: ASAHI INTECC CO., LTD.Inventors: Moritaka OGIDO, Yutaka ERIKAWA, Takeharu KATSURADA

Patent number: 11633567Abstract: A catheter includes a tubular inner layer, a reinforcement body disposed around the outer periphery of the inner layer, a protective layer covering the outer periphery of an end of the reinforcement body, and an outer layer covering at least the outer periphery of the protective layer. The protective layer covers the outer periphery of at least one end of reinforcement body, and the end of the reinforcement body covered with the protective layer is buried deeper in a side of the inner layer relative to a portion of the reinforcement body not covered with protective layer. The reinforcement body is prevented from lifting away from the inner layer when the catheter is bent even without increasing the outer diameter of the reinforcement body.Type: GrantFiled: April 10, 2020Date of Patent: April 25, 2023Assignee: ASAHI INTECC CO., LTD.Inventors: Yuta Kubo, Takeharu Katsurada, Moritaka Ogido

Patent number: 10888341Abstract: A balloon catheter prevents detachment of a balloon from an inner shaft without using a conventional sleeve or heat-shrinkable tube. The balloon catheter includes a balloon, an inner shaft, and a tip having a proximal end portion that covers an outer periphery of a distal end of the balloon. The distal end of the balloon is sandwiched between the inner shaft and the proximal end portion of the tip, thereby joining the distal end of the balloon to the inner shaft and the tip.Type: GrantFiled: July 24, 2018Date of Patent: January 12, 2021Assignee: ASAHI INTECC CO., LTD.Inventors: Takeharu Katsurada, Yuta Kubo, Moritaka Ogido

Patent number: 10722682Abstract: A catheter includes an inner layer, a reinforcement layer at least partially inside the inner layer or on an outer periphery of the inner layer, and an outer layer covering the inner layer and the reinforcement layer. The reinforcement layer has a wire wound so that a gap is present between adjacent portions of the wire. The inner layer has an uneven outer peripheral surface on which a protruded portion is formed in a location of the wire, and in which a depressed portion is formed in a location of the gap. The outer layer has a protrusion part that extends into the depressed portion of the inner layer, the protrusion part entering deeper than the reinforcement layer through the gap and extending in an axial direction of the catheter. The outer layer is not easily detached from the inner layer.Type: GrantFiled: March 23, 2017Date of Patent: July 28, 2020Assignee: ASAHI INTECC CO., LTD.Inventors: Yuta Kubo, Moritaka Ogido, Takeharu Katsurada
