  • Patent number: 11020899
    Abstract: An additive manufacturing system for printing three-dimensional (3D) parts includes a print foundation, a print head, a drive mechanism, and a supporting surface that creates an air bearing for parts under construction as they move through the system. The print head is configured to print a 3D part onto the print foundation in a layer-by-layer manner in a vertical print plane. The drive mechanism is configured to index the print foundation substantially along a horizontal print axis during printing of the 3D part. The support surface is provided by a table extending along the horizontal axis. The table has a plurality of air jets forming an air platen, which generates the air bearing for supporting the 3D part as it is incremented along the print axis.

  • Publication number: 20210149980
    Abstract: Connections among two different entities are identified by processing a collection of documents to identify one or more documents that contain co-occurring mentions of each of the two different entities. This relationship may be graphically displayed in a user interface with an icon or the like for each of the two entities, along with a graphical link interconnecting the entities. The graphical link can be an active element of the user interface that responds to user interactions by providing access to evidence within the collection of documents that substantiates the connection between the two entities. In one aspect, a search input form field in a user interface may be used to explicitly request documents that substantiate a relationship between two entities. In another aspect, a user may ground entity mentions by explicitly selecting documents that mention an entity of interest.

  • Patent number: 11000637
    Abstract: A system and method used to deliver a percutaneous ventricular assist device (pVAD) or other cardiac therapeutic device to a site within the heart, such as a site at the aortic valve. A flexible device is percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device. The pVAD is pushed in a distal direction while the arterial-side end of the flexible device is pulled in the proximal direction to advance the pVAD to the target site. A left ventricle redirector aids in orienting the pVAD and preventing migration of the flexible member towards delicate structures of the heart during advancement of the pVAD.

  • Publication number: 20210134401
    Abstract: A computer method of managing a workflow of scheduled nodes. The method comprises instantiating a computer instantiated mathematical model of workflow paths, wherein the mathematical model defines nodes to be scheduled, defines time-based anchors between the nodes, and sequence-based anchors between the nodes; for each workflow object, determining a workflow schedule for the workflow object by an application executing on a computer system, wherein the workflow schedule comprises a plurality of nodes and wherein the application determines the workflow schedule based on the time-based anchors and sequence-based anchors between nodes defined by the mathematical model; storing by the application context information about completion of the activities performed when performing the node associated with the workflow path of the workflow object; and changing the workflow schedule of the workflow object based on the context information about completion of the activities performed and based on the mathematical model.

    Abstract: Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector may be tracked by surgical robot system and displayed to a user. In some embodiments the end-effector element may be configured to restrict the movement of an instrument assembly in a guide tube. In some embodiments, the end-effector may contain structures to allow for magnetic coupling to a robot arm and/or wireless powering of the end-effector element. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.

  • Patent number: 10987456
    Abstract: A system and method for extracting a pVAD device that is implanted with a distal portion in an aorta of the heart and a drive line extending across an inter-atrial septum and out of the body via a superior vessel of the venous vasculature, include a first device that is introduced into a femoral artery and through the descending aorta used to engage a distal part of the pVAD device in the aorta of a patient using an instrument. A second, cutter, device is introduced into the venous vasculature superior to heart, advanced to a position adjacent the inter-atrial septum, and used to cut the pVAD drive line adjacent to the inter-atrial septum. After cutting, a first portion of the pVAD is withdrawn from the body via the venous vasculature, and a second portion is withdrawn from the body via the femoral artery.

  • Patent number: 10782138
    Abstract: A method, apparatus, and computer program product are described herein for determining pedestrian behavior profiles for road segments of a road network, from those pedestrian behavior profiles, determining the likelihood that an adverse pedestrian event will occur, and determining the action to be taken in response. Example embodiments may provide a mapping system including: a memory having map data; and processing circuitry. The processing circuitry may be configured to: receive data points associated with pedestrian movement; associate pedestrian movement with a road segment; determine, based on the data points, a pedestrian behavior profile for the road segment; and in response to the pedestrian behavior profile for the road segment indicating a likelihood for an adverse pedestrian event that satisfies a predetermined likelihood, cause at least one action in response thereto.

  • Publication number: 20200253635
    Abstract: An instrument for facilitating transseptal delivery of a cardiac therapeutic device is positionable in a left ventricle. The instrument includes an elongate shaft having a tubular lumen, the shaft having a proximal portion and a distal portion actively steerable between a generally straight position and a curved position. An external pull wire and an internal pull wire are each actuatable to move the distal portion to the curved position. The external pull wire extends internally through the proximal portion of the shaft and longitudinally along the exterior of the distal portion of the shaft, while the internal pull wire extends internally through the proximal portion of the shaft adjacent to the external pull wire, and extends internally through the distal portion of the shaft.

  • Patent number: 10550969
    Abstract: A connector has a cylindrical sleeve device having a first part, with an external screwthread on its outer side, and a second part, with an internal screwthread on its inner side. One of the screwthreads engages a corresponding screwthread on a further part when the device is in use. At least a portion of the said second part is yieldable. A locking part is provided with a screwthread which engages the other of the screwthreads of the cylindrical sleeve device when the connector is in use. The second part and the locking part have mutually engageable portions which, when the locking part is tightened relative to the cylindrical sleeve device, interengage to cause yielding of the second part or yieldable portion thereof. This effects locking of the cylindrical sleeve device with respect to such a further part when the connector is in use.
