  • Patent number: 10528702
    Abstract: Mechanisms are provided for communicating with a patient. The mechanisms generate a patient registry comprising a plurality of patient registry records, each patient registry record being associated with a corresponding patient and comprising personal and medical information about the corresponding patient. The mechanisms collect, for each patient registry record, first data regarding treatment of the corresponding patient and second data regarding communications made with the corresponding patient. The mechanisms determine, based on analysis of the first data and second data associated with each of the patient registry records, a mode of communication that is most likely to result in a successful treatment of patients. The mechanisms initiate a communication with a patient of interest using the determined mode of communication based on the results of the determination.

  • Patent number: 10428594
    Abstract: A connection is established between a pin connector and a box connector defined on a pair of tubular members such as casing segments in the field of oil and gas recovery. The pin connector and box connector include features for the protection of metallic-sealing surfaces during assembly, disassembly, transport and handling of the tubular members. The pin connector includes a stabbing flank with an inwardly tapered annular flank surface thereon, and an alignment protrusion extending outward with respect to the pin-side metallic sealing surface in a direction normal to a cone angle defined by the inwardly tapered annular flank surface. The alignment protrusion engages internal surfaces of the box connector to concentrically align the pin connector with the box connector, and thereby protects the metallic sealing surfaces from damage that might otherwise result from collisions between the pin connector and the box connector.

  • Publication number: 20190223881
    Abstract: Methods and devices for treating a cerebral aneurysm are described. The device may include a self-expanding resilient permeable shell made from elongate resilient filaments. At least some of the filaments have a distal region that extends beyond the distal end of the permeable shell and form an extension having a generally circular shape when expanded. The permeable shell has a radially constrained elongated state configured for delivery within a microcatheter and has an expanded state with a globular, axially shortened configuration. The permeable shell has a plurality of openings formed between the braided filaments. The distal regions of the plurality of filaments that form the extension may be braided, partially braided, or unraveled. Once deployed within the cerebral aneurysm, the extension is positioned near a dome of the cerebral aneurysm.
