  • Patent number: 11931041
    Abstract: Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state in which (a) the mesh is curved along its width, (b) the mesh is curved along its length, and (c) the mesh has an undulating contour across at least a portion of one or both of its length or its width. The mesh is configured to be positioned within the aneurysm in the deployed state such that the mesh extends over the neck of the aneurysm.

  • Publication number: 20200226182
    Abstract: A method and apparatus for identifying reviewers of documents is disclosed. In the method and apparatus, reviewers are identified for a set of documents. The reviewers are identified based at least in part on one or more attributes of the reviewers or one or more attributes of at least one document of the set of documents. An identity associated with a reviewer of the reviewers is made available to a user. After the reviewer is made available to the user, a selection of at least one reviewer is received from the user, and the set of documents are made available to the selected at least one reviewer.

  • Patent number: 10691877
    Abstract: Organizations maintain and generate large amounts of documentation and entities of these organizations often need to collaborate on generating and reviewing this information. There is a need to maintain and store this documentation remotely in such a way that the entities of these organizations may collaborate with each other. To ensure that entities of the organization can collaborate on documents, an overlay creation and storage system is described. The overlay may be usable by a computing device operated by the entities of the organization. Furthermore, information contained in the overlay may be injected into the document.

  • Patent number: 10567382
    Abstract: A method and apparatus for controlling access to documents retained by a document management and collaboration system is disclosed. The document management and collaboration system may generate one or more suggested privileges associated with one or more users. An access control policy may specify whether system-generated user privileges may be enforced. If they are enforced, access to one or more document may be made subject to the generated privileges.

  • Patent number: 10540404
    Abstract: A method and apparatus for forming a collection of documents is disclosed. In the method and apparatus, a plurality of documents are identified for inclusion in a document collection. The documents are identified based at least in part on one or more attributes of at least one document of the plurality of documents. A user is requested to confirm the document collection, and an instruction is received from the user indicating one or more documents of the plurality of documents may be included in the document collection. After the indication is received, the collection may be formed and made available to the user or one or more other users of a document management and collaboration system.

  • Patent number: 9880989
    Abstract: Organizations maintain and generate large amounts of documentation and entities of these organizations often need to collaborate on generating and reviewing this information. There is a need to maintain and store this documentation remotely in such a way that the entities of these organizations may collaborate with each other. To ensure that entities of the organization can collaborate on documents, a document annotation service is described that converts a text-based document, such as a word processing document, to a fixed-layout document, such as a coordinate-based document. Annotations can be received on the fixed-layout document. The annotations can then be mapped to the text-based document and downloaded to a user for viewing.

  • Patent number: 7547547
    Abstract: The present inventors identified aggregation of embryonic stem cells and embryoid bodies (EBs) as the cause of the difficulty in generating large numbers of the embryonic stem cells (ES) cell-derived tissues. To counter this, the invention provides a novel bioprocess where aggregation of spheroid forming cells, such as embryonic stem cells and spheroids, such as EBs is controlled, such as by encapsulation of within a matrix. As a result, EBs can be generated with high efficiency and cultured in high cell density, well-mixed systems. Well-mixed conditions facilitate measurement and control of the bulk media conditions and allow for the use of scalable bioreactor systems for clinical production of tissue. Therefore, the invention enables generation of ES cell-derived tissue on a clinical scale. The invention is also applicable to any spheroid-forming cells and other types of pluripotent cells.
