  • Publication number: 20190307542
    Abstract: A mesh deployment device having separate mesh deployment and actuation units is provided. A mesh deployment device includes an actuation unit and a mesh deployment unit configured to be releasably secured to the actuation unit. When the mesh deployment unit is secured to the actuation unit, a first actuation of the actuation unit moves the mesh deployment unit from an expanded condition to a collapsed condition and a second actuation of the actuation unit moves the mesh deployment unit from the collapsed condition to the expanded condition. The mesh deployment device may further include a mesh releasably secured to the mesh deployment unit. A third actuation of the actuation unit may release the mesh from the mesh deployment unit. Also provided is a kit including multiple mesh deployment units.

  • Publication number: 20190053929
    Abstract: A gastric tube for use in a bariatric surgical procedure includes an elongate tube and a movable component supported on an outer surface of the elongate tube. The elongate tube has a non-circular cross section along at least a portion of a length of the elongate tube. The movable component is movable between an unexpanded configuration and an expanded configuration. In the unexpanded configuration, the movable component is disposed in abutting engagement with the outer surface of the elongate tube. In the expanded configuration, the movable component bows outwardly from the outer surface of the elongate tube.

  • Patent number: 10105135
    Abstract: A surgical fastener applier is disclosed and includes a handle portion, a tubular member extending from the handle portion and defining a longitudinal axis, a drive member rotatably supported in the tubular member and in the handle portion, and a plurality of fasteners. The drive member is configured to rotate while in a deflected condition with respect to the longitudinal axis. The drive member includes a proximal portion, a central portion, and a distal portion, the central portion being relatively more flexible configuration as compared to at least one of the proximal portion and the distal portion. The plurality of fasteners is disposed within the tubular member and is configured to engage a portion of the drive member such that rotational motion of the drive member causes distal advancement of at least one fastener of the plurality of fasteners through the tubular member.

  • Publication number: 20180070947
    Abstract: The present disclosure relates to an insertion device including a shaft with a head supported on a distal end thereof. The shaft includes a proximal end with an engagement member that is configured to frictionally engage a distal end of a surgical fastening apparatus such that an interference fit is created therebetween to facilitate selective detachment of the insertion device from the surgical fastening apparatus. The head has an atraumatic configuration, and is dimensioned to be received in a body orifice.

  • Publication number: 20170360472
    Abstract: An optical obturator apparatus includes an obturator sleeve defining a longitudinal axis and having a longitudinal bore for receiving surgical instrumentation and a transparent window mounted to the obturator sleeve and being dimensioned and configured to pass through tissue. The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation.
