  • Patent number: 11904181
    Abstract: Methods and systems for selection of dosimetry levels and sphere amounts of radioactive compounds for use in a radioembolization procedure for procedure planning may include inputting activity parameter information into a dosimetry portal of a dosimetry selection tool; determining a customized activity based on the activity parameter information and one or more customized activity algorithms; generating one or more sphere amount and dosage recommendations based on the customized activity and one or more dosimetry selection algorithms; selecting one of the one or more sphere amount and dosage recommendations as a selected sphere amount and dosage recommendation; and generating a radioactive compound order for the radioembolization procedure based on the customized activity and the selected sphere amount and dosage recommendation.

  • Publication number: 20240009428
    Abstract: A plug may be used to plug a proximal end of a flashback chamber or an adapter in an intravenous catheter assembly. The plug may provide air venting of the flashback chamber or the adapter. The plug may include a body and a neck portion extending from the body. The neck portion may include one or more air vent channels, which may be aligned with a longitudinal axis of the plug. The neck portion may include one or more transverse channels, which may provide air venting and/or blood collection in case of leakage of blood into the plug.

  • Publication number: 20230248899
    Abstract: A delivery assembly includes a console including a vial containment region and a vial engagement mechanism extending from the console within the vial containment region. The engagement mechanism is configured to engage a vial assembly including a particulate material. The delivery assembly further includes a multi-port needle with a top distal port and bottom proximal port(s), the needle configured to puncture a septum of the vial assembly when the vial assembly is in the locked position, in which the top distal port is at a distance above the particulate material in the vial assembly. The ports are configured to inject a fluid into the vial assembly to mix with the particulate material upon actuation of the vial engagement mechanism in a first direction and to receive a resulting mixed fluid from the vial assembly upon actuation of the vial engagement mechanism in a second opposite direction.

  • Patent number: 11344851
    Abstract: A biological fluid separation device adapted to receive a biological fluid sample having a first portion and a second portion is disclosed. The device includes a housing having a first chamber having a first chamber inlet for receiving the biological fluid sample therein and a first chamber outlet. The housing has a second chamber having a second chamber inlet and a second chamber outlet, and a separation member separating at least a portion of the first chamber outlet and the second chamber. The separation member is adapted to restrain the first portion of the biological fluid sample within the first chamber and to allow at least a portion of the second portion of the biological fluid sample to pass into the second chamber. An actuator, such as a vacuum source, draws the biological fluid sample into the first chamber and the second portion into the second chamber.
