Abstract: One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. Occlusion devices can be integrated with a catheter or tube to occlude one or more proximal or distal landmarks of a stomach and a stapling guide may be used to occlude a lateral boundary of the stomach to define a cavity. A volume of the potential resultant sleeve may be determined by inserting fluid or gas into the catheter or tube, measuring pressure, and calculating the volume of the cavity.

Abstract: The systems and methods are provided for the dynamic processing of API requests received by an API execution service. The API execution service may map out a dependency graph based on dependency relationships between all the actions involved in processing the API requests, some of which can be determined from the API definitions and configurations. From the dependency graph, an execution plan can be generated that represents a request processing pipeline conveying the optimal order and arrangement to perform the actions (e.g., serially, in parallel). The execution plan can be followed to process API requests and its performance monitored. The API execution service may dynamically modify this execution plan used to process API requests as it becomes apparent that the execution plan is no longer optimal.

Abstract: An end effector for use by a surgeon to staple an anatomical structure of a patient during a minimally invasive procedure can include an anvil, a cartridge, and a knife. The anvil includes a proximal end, a distal end, and a face that is positionable on a first side of the anatomical structure. The cartridge is configured to house a plurality of staples and includes a proximal end, a distal end, and a face that is positionable on a second side of the anatomical structure. The knife has a cutting edge, the knife being operably configured to move from a first position at about a distal end of the end effector to a second position at about a proximal end of the end effector. The distal end of the anvil is movably coupled to the distal end of the cartridge.

Abstract: One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. The one or more medical devices may include a laparoscopic sleeve gastrectomy stapling guide in conjunction with a calibration tube in accordance with one or more examples. According to an example, the calibration tube may be a flared, multi-diameter calibration tube. The flared, multi-diameter calibration tube may have a first diameter along a portion of the tube and a second diameter that may larger than the first diameter along at least another portion of the tube. The calibration tube may be used in conjunction with the stapling guide to align stomach such that it may be stapled along the stapling guide (e.g., to perform the vertical sleeve gastrectomy).

Abstract: An end effector for use by a surgeon to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple, the first staple having a first open leg with a first tip, a second open leg with a second tip, and a first crown coupling the first open leg and the second open leg, and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, comprises the first tip and the second tip crossing the first midline axis of the first crown in a formed configuration.

Abstract: At a managed control plane service, end-user application programming interfaces (APIs) of an application to be implemented at a provider network are determined. A set of common operational requirements of the application, to be fulfilled without obtaining program code for the requirements, are identified. In response to an invocation of an end-user API of the application, computations are performed at a resource selected by the managed control plane service, and one or more tasks to satisfy a common operational requirement are initiated by the managed control plane service.

Abstract: An end effector for use by a surgeon to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. Each of the anvil and the cartridge has a face that is positionable on the anatomical structure. The anvil is coupled to the cartridge at first and second ends. The anvil is movable relative to the cartridge to define a first gap between the faces at the first ends that is different from a second gap between the faces at the second ends.

Abstract: An end effector for use by a surgeon to staple an anatomical structure of a patient during a minimally invasive procedure includes a first jaw and a second jaw. The first jaw has a first end, a second end, a longitudinal axis, and an anvil, which has an anvil face positionable on a first side of the anatomical structure. The second jaw has a first end, a second end, a longitudinal axis, and a cartridge, which has a cartridge face positionable on a second side of the anatomical structure. The end effector includes a first coupling that couples the first end of the first jaw to the first end of the second jaw; and a second coupling that movably couples the second end of the first jaw to the second end of the second jaw and includes a rigid link connected to the first jaw and the second jaw.

Abstract: An end effector for stapling and cutting an anatomical structure includes an anvil, a cartridge, and a blade. The anvil has an anvil face and a plurality of staple pockets positioned on the anvil face. The cartridge has a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples. Each of the plurality of staples comprises a first staple leg, a second staple leg, and a crown connecting the first and second staple legs and having a midpoint. Each of the plurality of staples comprises an open staple configuration and a closed staple configuration where a first portion of the first staple leg and a second portion of the second staple leg are bent relative to the crown such that the first portion of the first staple leg and the second portion of the second staple leg cross the midpoint of the crown.

Abstract: A method for filtering a precipitatable constituent from an extraction solution through a filter apparatus includes pre-cooling at least a portion of the filter apparatus to a reduced temperature that is effective to precipitate the constituent from the extraction solution. At least the cooled portion of the filter apparatus may be thermally conductive to act as a heat sink for the extraction solution being passed through the filter apparatus. The reduced temperature facilitates removal of the precipitatable constituent from the extraction solution.

Abstract: An end effector for a medical device includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket and a second staple pocket, each defined by the anvil face. The first staple pocket includes a first surface having a first depth, and the second staple pocket includes a second surface having a second depth. The cartridge has a first staple having a first height in an open configuration, a first driver, a second staple having a second height in an open configuration, and a second driver. A first staple formation distance is defined by a first distance between the first driver and the first surface of the first staple pocket when the anvil and the cartridge are in a closed position. The first staple formation distance differs from a second staple formation distance.
