Each connector of the plurality of connectors joins adjacent segments in the series of individual segments to one another such that a first end of a first segment and a second end of a second segment in the series of individual segments are attached to a connector of the plurality of connectors. A spacer of the plurality of spacers is disposed between each pair of adjacent segments in the series of individual segments. Each of the segments in the series of individual segments is electrically insulated from an adjacent segment in the series of individual segments.

Abstract: Systems, methods, and machine-readable media for creating, deleting, and restoring volume snapshots in a remote data store are disclosed. A storage volume and a storage operating system are implemented in a software container. Through a user interface, a user may create a snapshot of the volume to a cloud storage. A user may also delete individual snapshots from the cloud storage. Further, deletion of a most recent snapshot may occur by awaiting deletion (though marking as deleted to the user) until a next snapshot is received. Snapshots in the cloud storage are manipulatable even after destruction of the source volume (by destruction of the container, for example). A controller outside the container is used by implementing the same API as the controller in the container had. Full restores of snapshots in the cloud are also possible even when the original container and volume have been destroyed.

Abstract: A platelet-rich fibrin (PRF) three-dimensional, adhesive, biocompatible and biodegradable scaffold and/or membrane is obtained by collecting a blood sample, followed by centrifugation of the blood sample to obtain a platelet-rich fibrin clot and an exudate followed by compressing platelet-rich fibrin clot to extract the exudate until the final product being a platelet-rich fibrin three-dimensional, adhesive, biocompatible and biodegradable scaffold is obtained. A hyper-acute serum is obtained by collecting a blood sample, followed by centrifugation of said blood sample to obtain a platelet-rich fibrin clot and an exudate followed by compressing platelet-rich fibrin clot to obtain the membrane and extract the exudate being the final product hyper-acute serum. A process for the preparation of a platelet-rich fibrin three-dimensional, adhesive, biocompatible and biodegradable scaffold and/or membrane and a hyper-acute serum is also provided.

Abstract: Examples of a stent are provided with interlocking joints removably coupling adjacent axial stent segments. Mating elements forming the interlocking joints maintain engagement when the stent is in the radially compressed configuration, for example, during tracking of the stent to a treatment site of a body vessel, and become disengaged during radial expansion of the stent. When disengaged, the disconnected the axial stent segments remain discrete stent structures separated from one another along the point of treatment.

Abstract: A prosthesis is disclosed including an expandable frame having a first region and a second region coupled to one another. The first region includes a transition segment and a flex segment. The stent members of the transition segment have proximal and distal apices arranged in a peak-to-peak relationship with one another. At least a portion of proximal and distal apices of the transition segment remains uncoupled to one another. The flex segment includes a stent member having proximal and distal apices arranged in a peak-to-valley relationship with the transition segment. Longitudinal tie bars are intermittently coupled between apices the flex segment and the transition segment at coupling joints. The coupling joint is located where the proximal and distal apices of the stent members of the transition segment remain uncoupled to one another. The transition and flex segments may form an alternating pattern. A flareable proximal portion may be included.

Abstract: Disclosed herein is an intraluminal support device including a closed cell design on at least one end of the device. In such a device, the closed cell structure is formed by connecting all peaks of an ultimate ring to all peaks of a penultimate ring, and all valleys of the ultimate ring to all valleys of the ultimate ring. The support device expands evenly due to this structure.

Abstract: The present disclosure describes intraluminal support devices having high radial stiffness regions with smaller diameter and low radial stiffness regions with larger diameter. When deployed to the vasculature of a patient in need of treatment, the high radial stiffness region is sized such that it has approximately the diameter of the vessel in need of treatment, so that it produces substantially zero chronic radial force when the vessel is not being subjected to external compression. The low radial stiffness regions anchor the device to the vessel wall and provide a less-abrupt transition from the high radial stiffness structure. Methods of making and using such devices are also described.

Abstract: A method includes storing a copy of information, corresponding to a data set, in each of a plurality of data formats, and determining one or more portions of a search criterion to be associated with one or more sets of one or more characteristics. For each portion, based on the associated characteristics, a search is executed on a copy of information stored in a particular data format using a corresponding search algorithm to obtain a set of intermediary search results. A set of final search results corresponding to the search criterion is determined based on two or more sets of intermediary search results.

Abstract: A perfusion device and a delivery system for repair of a damaged portion of a body vessel. Perfusion device can include a tubular body that is self-expandable, having a proximal portion, a distal portion, and an intermediate portion. One or more series of barbs can be disposed circumferentially along the intermediate portion. Barbs are capable of penetrating into the tunica intima and tunica media of said vessel wall upon insertion of said device into said body vessel, and not into said tunica adventitia. A graft can be associated with the tubular body. Graft has a proximal end and a distal end, and preferably extends entirely along a luminal wall of the tubular body. Graft may also extend along an exterior surface of the tubular body at the proximal and distal portions. Delivery devices for the perfusion implant and methods of delivering the perfusion implant are also provided.

Abstract: Examples of a stent is provided with interlocking joints removably coupling adjacent axial stent segments. Mating elements forming the interlocking joints maintain circumferential and axial engagement when the stent is in the radially compressed configuration, for example, during tracking of the stent to a treatment site of a body vessel, and become disengaged during radial expansion of the stent. The length of mating elements may be sized as large as the strut width. When disengaged, the disconnected the axial stent segments remain discrete stent structures separated from one another along the point of treatment.

Abstract: The present disclosure is generally directed to systems and methods for utilizing an operating schedule to place a satellite communication device in a sleep state for reducing power consumption in the satellite communication device during periods of time when no satellite is available to communicate with the satellite communication device. The operating schedule, which can be a wake-up schedule and/or a sleep schedule, is dynamically updated by a scheduling server that receives two-line element (TLE) data from a TLE server on a recurring basis and uses the TLE data to determine timing information pertaining to line-of-sight visibility of one or more satellites to the satellite communication device. A push routine is then used by the scheduling server to periodically push the timing information to the satellite communication device for dynamically updating the operating schedule of the satellite communication device.

Abstract: Techniques are herein described for creating a scalable IMAP4 compliant email system using a NoSQL database and a distributed full text search engine. Data for each email message is stored in multiple tables to avoid storing redundant data unnecessarily. However, a full text search index is created based on a single table as if the index refers to a single table. In embodiments herein described, the single index is created on the fields of a message metadata table with virtual fields added to the table that are derived from the message content. During this process, data is pulled from a message table in “blob” format and broken down into corresponding fields and data items, so the data items may be converted and placed in the proper virtual fields for index creation. Each blob section that is converted is cached, so the same blob section does not need to be converted multiple times. After index creation, the index may be used to search for emails based on metadata and data within the body of the email.
