  • Patent number: 12667365
    Abstract: A vascular occlusion catheter for at least partial occlusion of a target vessel includes proximal and distal shafts, with an occlusion balloon connected therebetween. The proximal shaft has a proximal internal lumen, in fluid communication with the occlusion balloon. The distal shaft has a distal internal lumen. A hypotube having an internal lumen extends through the proximal lumen and the occlusion balloon and into communication with the distal lumen. The catheter includes at least one of (i) a distal sensor positioned within the distal lumen and facing an opening formed in the distal shaft, or (ii) the proximal shaft further includes a sensor lumen, and a proximal sensor is positioned within the sensor lumen and facing an opening formed in the proximal shaft. A display hub is mounted to the proximal shaft, and is electrically connected with the at least one of the distal sensor or the proximal sensor.

  • Patent number: 12527937
    Abstract: An inflation control system is provided for use with an occlusion catheter having an inflatable occlusion member for at least partial occlusion of a patient vessel. The inflation control system includes a fluid source in fluid communication with the inflatable occlusion member, a pressure source coupled to the fluid source and configured to move fluid between the fluid source and the inflatable occlusion member, and a controller operably coupled to the pressure source. The controller is configured to receive at least one patient vital sign as feedback and operate the pressure source to modulate an inflation volume of the occlusion member based, at least in part, on the feedback.

  • Patent number: 12215332
    Abstract: The present invention pertains to the field of imparting or increasing resistance against fungal pathogens, in particular soy-beanrust, in plants, plant parts, and/or plant cells. This is achieved by increasing the content of scopoletin, scopolin and/or, most preferably, scoparone (6,7-di-methoxycoumarin) in a plant, plant part and/or plant cell. This can in particular be achieved by establishing and/or increasing the expression of an OMT3 enzyme and an F6H1 protein in the respective plant, plant part and/or plant cell; a further way would be to apply a formulation or solution containing scopoletin and/or, most preferably, scoparone to the plant, plant part and/or plant cell. The invention correspondingly also provides proteins, enzymes, expression constructs, plants, plant parts and/or plant cells. In this respect the invention also provides variants of the OMT3 enzyme.

  • Publication number: 20240327472
    Abstract: The present invention is directed to a modified clostridial neurotoxin comprising a botulinum neurotoxin A (BoNT/A) Hcc domain, wherein the Hcc domain comprises a modification of methionine 1144 (MI 144), and wherein the modification increases oxidative resistance of the modified clostridial neurotoxin when compared to an otherwise identical clostridial neurotoxin lacking the modification. Also provided are (inter alia) corresponding methods for producing the same, methods for selecting oxidation resistant clostridial neurotoxins, nucleic acids encoding the same, and therapeutic uses of said modified clostridial neurotoxins.

  • Publication number: 20240189828
    Abstract: A machine for comminuting laminated glass members, such as automotive windshields and architectural glass, comprises infeed rollers feeding the member over a breaker bar, where an impactor assembly breaks the glass into small fragments and the plastic disposed between layers of the glass member into larger fragments, so that a size-based separation may be employed. The speed of the infeed rollers is controlled responsive to the thickness of the glass member.
