Patent number: 12011174Abstract: An occlusion device with particular utility in occlusion of left atrial appendages is described. The occlusion device utilizes an inflatable balloon comprising a proximal portion to inflate with an inflation fluid delivered by an outer catheter body and conform to a shape of the left atrial appendage and a distal portion to fill with an adhesive delivered by an inner catheter body. The distal portion of the inflatable balloon sticks to the tissue wall of the left atrial appendage. The outer catheter body is configured to position the inner catheter body inside the outer catheter body.Type: GrantFiled: April 28, 2021Date of Patent: June 18, 2024Assignee: Terumo CorporationInventors: Brian Gray, Anup Dasnurkar, Maricela Walker, Michael Martel, Hiroki Kamiuchi

Publication number: 20240173529Abstract: A connector, comprising: a housing which has a first port, a second port, and a first chamber in communication with the first port and the second port; a cover, which is connected to the housing and which has a second chamber in communication with the first chamber; and a bulging portion, which is disposed in the first chamber and protrudingly extends toward the second chamber. A side groove which obliquely curves and extends towards the second chamber is provided in the first chamber. The groove structure of the connector can guide a portion of fluid which is flowing into the first chamber from the first port towards the second chamber, so as to form a spiral upward vortex, thereby enlarging a flushing region, increasing the flushing efficiency, and reducing the risk of pollution.Type: ApplicationFiled: April 25, 2022Publication date: May 30, 2024Applicant: TERUMO CORPORATIONInventors: Hongyuan HU, Binhua YAN, Juan ZHANG, Dianhong CHEN
