  • Patent number: 11553855
    Abstract: A device for use in bariatric surgery includes a flexible hollow tube extending from a proximal end to a distal end and defines a channel therebetween. A series of openings is defined in a distal portion of the tube allowing for fixation of tissue using suction. A flexible member has an initial position disposed alongside the tube and is deployable to a subsequent position in which the flexible member engages a greater curvature of a stomach. The flexible member is configured to be deployable to automatically assume a shape of a greater curvature of a stomach. The flexible member includes a bulging region and a tapering region when deployed. The flexible member is releasably attached to the distal end of the tube.

  • Patent number: 11123066
    Abstract: A surgical fastener applying apparatus includes an elongate body portion having proximal and distal ends, an end effector including a first movably coupled to a second jaw that is positioned at the distal end of the elongate body portion, and an introducer member. The introducer member has proximal and distal portions, and is configured and dimensioned for releasable connection with the end effector. The introducer member is at least partially formed from a flexible material, and is configured and dimensioned to separate target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws of the end effector.

  • Patent number: 10389838
    Abstract: Disclosed are various embodiments for client-side predictive caching of content to facilitate use of the content. If account is likely to commence use of a content item through a client, the client is configured to predictively cache the content item before the use is commenced. In doing so, the client may obtain an initial portion of the content item from another computing device. The client may then initialize various resources to facilitate use of the content item by the client. The client-side cache may be divided into multiple segments with different content selection criteria.
