  • Patent number: 10639184
    Abstract: A gastric calibration tube includes a flexible elongate member, a pushing member, and a balloon member. The flexible elongate member has a proximal end portion, a distal end portion, and an outer surface that extends between the proximal and distal end portions. The outer surface defines a side opening. The flexible elongate member defines a lumen that is in communication with the side opening. The pushing member has a proximal portion and a distal portion. The distal portion is advanceable through the lumen of the flexible elongate member and out of the side opening of the flexible elongate member. The balloon member is secured to one or both of the flexible elongate member and the pushing member. The balloon member is inflatable to fix the gastric calibration tube within a patient's stomach.

  • Publication number: 20190167307
    Abstract: A surgical instrument includes a stationary shaft defining a conduit and a movable shaft slidably disposed therein. A surgical tool extends distally from the movable shaft and a cup extends distally from the stationary shaft. The cup includes a body defining one or more channels, an annular rim disposed at the distal end portion thereof and defining a plurality of apertures each in fluid communication with one of the channels, and a cap disposed at the proximal end portion of the body and defining a lumen fluidly coupling the one or more channels with the conduit. A central aperture of the cap slidably receives the surgical tool and/or the movable shaft as the movable shaft slides from a retracted position, wherein the surgical tool is disposed proximally of the distal end portion of the cup, and an extended position, wherein the surgical tool extends through and distally from the cup.

  • Patent number: 10182933
    Abstract: A gastric tube for use in a bariatric surgical procedure includes an elongate tube and an anchor. The elongate tube has a proximal end portion and a distal end portion and defines a lumen along a length thereof. The proximal end portion defines an opening in communication with the lumen. The elongate tube includes a blunt tip, a light source, and an outer surface. The blunt tip is formed on the distal end portion and is at least partially transparent. The light source is in communication with the blunt tip for illuminating at least the blunt tip. The outer surface extends between the proximal and distal end portions and defines a side opening in communication with the lumen.
