  • Publication number: 20230149021
    Abstract: Retrieval of material from vessel lumens can be improved by use of a distal element comprising an expandable mesh. a treatment device includes an elongated member having a proximal portion and a distal portion configured to be positioned within a blood vessel at a treatment site at or near a thrombus. A distal element comprising a plurality of woven filaments defining a shaft at a proximal portion and a body distal of the shaft is coupled to the distal portion of the elongated member via a connection assembly. In an expanded state, at least a portion of the distal element is configured to be in apposition with the blood vessel wall at the treatment site to anchor or stabilize the elongated member with respect to the blood vessel. The distal element can be electrically coupled to an extracorporeal current generator.

  • Patent number: 11641044
    Abstract: A housing for a button cell battery includes a top, a can and a grommet. The skirt of the can extends between a top panel and a free end, and includes a substantially vertical first section and an outwardly tapered second section. The first section extends from the top panel of the can. The second section extends from the first section. Upon assembly of the housing, a flow path is defined between an outer surface of the skirt of the grommet and the inner surface of the skirt of the can. The flow path allows air to escape during the assembly, thus minimizing the risk of gas being entrapped within the interior of the housing of the finished cell battery.

  • Patent number: 11554483
    Abstract: Deep machine learning methods and apparatus, some of which are related to determining a grasp outcome prediction for a candidate grasp pose of an end effector of a robot. Some implementations are directed to training and utilization of both a geometry network and a grasp outcome prediction network. The trained geometry network can be utilized to generate, based on two-dimensional or two-and-a-half-dimensional image(s), geometry output(s) that are: geometry-aware, and that represent (e.g., high-dimensionally) three-dimensional features captured by the image(s). In some implementations, the geometry output(s) include at least an encoding that is generated based on a trained encoding neural network trained to generate encodings that represent three-dimensional features (e.g., shape). The trained grasp outcome prediction network can be utilized to generate, based on applying the geometry output(s) and additional data as input(s) to the network, a grasp outcome prediction for a candidate grasp pose.

  • Publication number: 20220289537
    Abstract: A robot agent (102) includes an electro-mechanical subsystem (202), a sensor subsystem (204) having one or more sensors, and a computer hardware subsystem (206) to execute one or more sets of executable instructions (212, 214, 216, 218, 220). The one or more sets of executable instructions manipulate the robot agent to predict an action to be implemented by the robot agent in performing a task (112) and predict whether the robot agent will fail in performing the action. The one or more sets of executable instructions further manipulate the robot agent to, responsive to predicting the robot agent will fail in performing the action, obtain guidance input (116) for the first action from at least one guidance source, the guidance input representing guidance for performing the action by the robot agent, and manipulate the electro-mechanical subsystem to perform the action using the guidance input.

  • Publication number: 20220287733
    Abstract: Systems and methods for detecting and disrupting obstructions (such as clot material) within a blood vessel are disclosed herein. In some examples, the present technology comprises a system for detecting and disrupting a clot in a cerebral blood vessel of a patient, where the system comprises a treatment environment, a detection system, and an energy delivery device. The detection system may be configured to determine the presence of a blood clot within a cerebral blood vessel of a patient. In some embodiments, the detection system is configured to obtain data characterizing a position of the clot within the treatment environment. The energy delivery device can be configured to receive the data characterizing the position of the clot and, based on the data, deliver energy to the clot, thereby disrupting the clot and restoring blood flow in the affected blood vessel.

  • Publication number: 20220202431
    Abstract: Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can an interventional element configured to be delivered to a treatment site and to be electrically coupled to an extracorporeal power supply. The interventional element can be surface treated (e.g., via electrochemical anodization) to achieve a desired electrical conductivity gradient over the surface of the interventional element. The electrical conductivity gradient can result in a more desirable surface charge distribution upon delivery of electrical current to the interventional element.

  • Publication number: 20220012200
    Abstract: Bandwidth consumption for IO paths between a storage system and host may be managed. It may be determined whether there is congestion on a front-end port (FEP) link. For example, the storage system may monitor for a notification from the switch in accordance with a Fibre Channel (FC) protocol. If a notification is received indicating congestion on an FEP link, the bandwidth thresholds (BWTs) for one or more IO paths between the storage system and one or more hosts that include the FEP link may be reduced. The host port BWTs may continue to be reduced until a congestion notification communication has not been received for a predetermined amount of time, in response to which the host port BWTs for one or more host port links on IO paths that include the FEP link may be increased. Similar techniques may be employed for an FEP link determined to be faulty.

  • Patent number: 10870196
    Abstract: A tool has a working member, a plurality of expansion members, and a handle that is rotatable relative to the working member. The handle has a longitudinally extending chamber in which a portion of the working member having cam surfaces is disposed. The handle also has a plurality of slots in which the plurality of expansion members are disposed. When a torque is applied to the tool, the cam surfaces of the working member cooperate with the plurality of expansion members to cause at least a portion of each of the plurality of expansion members to be moved outwardly from the slots to thereby cause the handle to change from having a first cross-sectional shape to a second cross-sectional shape. At least one spring is interposed between each of the plurality of expansion members and the handle for causing the handle to revert back to the first cross-sectional shape upon a removal of the torque as applied to the tool.
