  • Publication number: 20190175173
    Abstract: A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

  • Patent number: 10314565
    Abstract: Surgical devices and methods are described. The surgical devices can generally include a housing having one or more actuators such as a closure actuator. An elongate shaft can extend distally from the housing and an end effector can be selectively coupled to a distal end of the shaft. The surgical device can include various features that prevent a user from actuating the device when the end effector is not properly coupled to the shaft. More specifically, the housing can include a locking member that can be pivoted or otherwise move relative the housing to cause various internal features of the housing to move to a ready-to-load position. With the locking member and actuator so positioned, an end effector can be loaded onto the shaft and the locking member can be moved from the ready-to-load position to the ready-to-actuate position, thus allowing the closure actuator to be in a ready-to-actuate position.

  • Patent number: 10299785
    Abstract: Surgical access devices having wound closure features incorporated as part of the device are provided. The devices allow suture to be inserted directly into the device and operated to close an opening through which the device is disposed as or shortly after the device is removed from the surgical site. Further, the wound closure features allow for various orientations of wound closure to be achieved by adjusting an angle at which the suture enters tissue surrounding the opening to be closed. Some of the wound closure features provided for include openings formed in both the housing and cannula of the surgical access device, multiple openings formed in one or both the housing and cannula, locations of the openings being adjustable or otherwise movable, and various flexible seals. Other features, as well as methods of closing an opening through which the surgical access device was disposed, are also provided.

  • Publication number: 20190156950
    Abstract: Various systems and methods for predicting metabolic and bariatric surgery outcomes are provided. The systems and methods can also provide predictions for non-surgical metabolic and bariatric treatments. In general, a user can receive predictive outcomes of multiple bariatric procedures that could be performed on a patient. In one embodiment, a user can electronically access a metabolic and bariatric surgery outcome prediction system, e.g., using one or more web pages. The system can provide predictive outcomes of one or more different bariatric surgeries for the patient based on data gathered from the user and on historical data regarding outcomes of the different bariatric surgeries. The system can additionally provide predictive outcomes for not having any treatment and/or a comparison of the predictive outcomes of the one or more different bariatric surgeries to the predictive outcomes for not having any treatment.
