Patent number: 11383023Abstract: When imaging an imaging subject, a pixel value is maintained in a state of small fluctuation of the pixel value over an entire expected duration. A generation device includes: an imaging information acquiring unit acquiring information of an imaging site of an imaging subject; a subject information acquiring unit acquiring information of the imaging subject; and a protocol generation unit generating an injection protocol for a contrast medium based on the information of the imaging site and the information of the imaging subject, wherein the protocol generation unit generates the injection protocol including a first phase in which an injection rate decreases with a first acceleration, and a second phase which follows the first phase and in which the injection rate decreases with a second acceleration, and the injection rate at a start of the second phase is higher than the injection rate at an end of the first phase.Type: GrantFiled: November 16, 2017Date of Patent: July 12, 2022Assignee: NEMOTO KYORINDO CO., LTD.Inventors: Masayuki Dembo, Kazumasa Masuda, Shigeru Nemoto

Patent number: 11369809Abstract: The present invention is directed to methods for treating neurodegenerative diseases and/or improving cognitive function, in particular those associated with protein oligomers, aggregates or deposits, using acoustic energy, such as ultrasound. An 5 example of such a neurodegenerative disease is Alzheimer's disease. The present invention provides a method of improving cognitive function and/or memory in an individual with impaired memory and/or executive function, the method including the steps of identifying a region of the brain of the individual to be treated with acoustic energy, applying a clinically safe level of acoustic energy to the region, thereby 10 saturating or substantially saturating the region with acoustic energy, thereby improving memory in the individual.Type: GrantFiled: June 19, 2015Date of Patent: June 28, 2022Assignee: THE UNIVERSITY OF QUEENSLANDInventors: Juergen Goetz, Gerhard Leinenga

Patent number: 11351513Abstract: A device (1) for producing a solution of at least one liquid first medium and at least one second medium has a first container (2) for the first medium and a second container (3) for the second medium. Each container (2, 3) is connected to a supply line of a static mixer (9) via a pump (4, 5) that can be regulated by a controller (6). A sensor (10) is connected to the controller (6) downstream of the static mixer (9) in the flow direction. A branching valve (17) is downstream of the static mixer (9) in the flow direction and is controlled by the controller (6). A sterile filter (11) is downstream of the static mixer (9) and has an RFID tag (15) that stores process-relevant data to at least be read by the controller (6). A method also is provided for producing a solution using the device.Type: GrantFiled: August 29, 2016Date of Patent: June 7, 2022Assignee: Sartorius Stedim Biotech GmbHInventors: Franziska Krumbein, Alexander Tappe

Patent number: 11344315Abstract: A delivery system for the delivery of embolic agents to a patient includes a control valve assembly interconnecting first, second, third and fourth conduits, wherein the control valve assembly selectively moves between first, second, and third states under the control of a medical professional. In the first state, the first conduit communicates with the second conduit for transmitting a solution of embolic agents between a first syringe secured to the first conduit and a second syringe secured to the second conduit. In the second state, the second conduit communicates with the third conduit for transmitting the solution of embolic agents from the second syringe to a delivery catheter secured to the third conduit. In the third state, the third conduit communicates with the fourth conduit for flushing the delivery catheter via a third syringe, which is filled with saline, connected to the fourth conduit.Type: GrantFiled: February 19, 2020Date of Patent: May 31, 2022Inventor: Frank Levy
