  • Patent number: 11944768
    Abstract: A method of using a catheter assembly for inserting in a fluid filled space in a body includes providing a main body having a first end portion and a second end portion. The first end portion is positioned within the fluid filled space. The second end portion is adjusted to extend outwardly from the fluid filled space when the first end portion is positioned within the fluid filled space. A catheter tip is connected to the second end portion of the main body. The catheter tip includes a housing having a cavity defined therein and a rotating element positioned within the fluid filled space. The rotating element is rotated within the cavity of the housing to impart movement of the first end portion of the main body within the fluid filled space.

  • Publication number: 20230418913
    Abstract: In a server configured to operate on a network, secured access to shared digital content may be implemented by analyzing information about a first user and a second user with a neural network trained with a machine learning algorithm to determine a relationship between the first and second users. The first user may be granted access to one or more content items belonging to the second user based on the determined relationship and the second user's access to the one or more content items may be disabled. The first user's access to the content items may be disabled when the second user requests access to them and access of the content items may be returned to the second user after access for the first user to the one or more content items has been disabled.
