  • Patent number: 11484311
    Abstract: A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

  • Patent number: 9713468
    Abstract: A method of deploying a surgical fastener into a patient by introducing the fastener into a body of a patient while the fastener is in a first shape having a first loop with a back span and an original size and shape. The method then involves moving end segments of the fastener away from each other substantially along an entire length thereof while keeping the back span in substantially its original size and shape. The method then involves forming the fastener into a second loop having a width greater than a width of the first loop.

  • Patent number: 8945163
    Abstract: Methods and devices are provided for cutting and fastening tissue. In one embodiment, a surgical device can be used to at least partially transect a stomach by not cutting and/or not fastening a portion of tissue engaged in an end effector located at the device's distal end. A portion of the stomach can be engaged by the end effector, and the end effector can be actuated to cut and/or to apply one or more fasteners to tissue engaged in a distal portion of the end effector but not to cut and/or apply fasteners to tissue engaged in a proximal portion of the end effector. In a similar way, the surgical device can be used in any surgical procedure in which it is desired to cut and/or fasten a distal portion of tissue engaged by the end effector but not a proximal portion of tissue engaged by the end effector.

  • Publication number: 20120165793
    Abstract: Devices and related methods are provided for the controlled delivery of a therapeutic to a targeted location within a body. More particularly, methods and devices are provided for controlling the rate of passage of an orally administered pill through a body, as well as for controlling the delivery of a therapeutic within the pill at a specific location within the body. Various types of devices, generally referred to herein as “catchers,” are provided that can actively catch a pill as it passes through a body. The catcher can hold the pill at a specific location within the body until a predetermined event occurs, such as partial or complete administration of a therapeutic within the pill. The catcher can then release the pill upon command and/or upon the occurrence of the predetermined event to allow the pill to pass out of the body. In other embodiments, various types of pills are provided that can actively engage a catcher and remain engaged with the catcher until a predetermined event occurs.

  • Patent number: 7914511
    Abstract: An exemplary method of reducing the volume of a stomach comprises providing an adhesive applier and a biocompatible adhesive. The exemplary method further comprises introducing at least a portion of the adhesive applier into the stomach and dispensing the adhesive through the adhesive applier into the stomach. The adhesive may be applied between the submucosa and muscle layers of the stomach to reduce the volume of the stomach. The adhesive may alternatively be applied in layers onto the inner surface of the stomach. Alternatively, a non-expandable member may be introduced into the stomach, and an adhesive may be used to secure the non-expandable member to the stomach. Such uses may provide a treatment for morbid obesity. An adhesive may also be used to provide flow restriction, such as by injecting the adhesive between the submucosa and muscle layers of a cardia or rectum.
