The method also includes resizing a put-together arrangement defined following positioning the can over the grommet and positioning the grommet over the top from a first, expanded configuration to a second, constrained configuration, where an inner diameter of the skirt in the second section is substantially equal to the inner diameter of the skirt in the first section following resizing.

Abstract: Devices and methods for deploying self-cinching surgical clips. A device can access at least two layers of tissue or material from only one side of the tissue or material and puncture through the two layers of tissue or material. The various configurations of clips disclosed herein can be made of a superelastic material such as Nitinol, and have a constrained and a relaxed state, and no sharp edges or tips so as to reduce tissue irritation following deployment. The clip can be disposed within the housing of the delivery device and held in a constrained state until deployment wherein the clip assumes its relaxed state, where the ends of the clip can be brought into close approximation, thereby securing the layers of tissue or material together.

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.

Some disclosed valves comprise a resiliently collapsible frame having a neutral configuration and a collapsed deployment configuration. Some disclosed frames can self-expand to the neutral configuration when released from the collapsed deployment configuration. Collapsing a disclosed valve can provide convenient access to the sewing ring, such as for securing the valve to the implantation site, as well as for the insertion of the valve through relatively small surgical incisions.

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.

Abstract: Compressible heart valve annulus sizing templates suitable for minimally-invasive or otherwise reduced accessibility surgeries. The sizing templates may be folded, rolled, or otherwise compressed into a reduced configuration for passage through an access tube or other such access channel. Once expelled from the access tube the sizing templates expand to their original shape for use in sizing the annulus. The templates may be formed of an elastomeric polymer material such as silicone, a highly elastic metal such as NITINOL, or both. Grasping tabs or connectors for handles permit manipulation from outside the body. A NITINOL wireform may be compressed for passage through an access tube and expelled from the distal end thereof into a cloth cover to assume a sizer shape.

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.

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.

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).
