  • Patent number: 9265502
    Abstract: A delivery assembly includes a ring sleeve that fits snugly over a main endoscope on the distal end of the endoscope. An extension tube projects distally away from the ring sleeve and may be made integrally with the sleeve. The extension tube is off-axis from the ring sleeve and endoscope. A tube-like inner carrier is reciprocatingly disposed inside the extension tube. One or more resilient tissue compression rings are placed in a stretched configuration on the inner carrier. To push the rings off the carrier, the carrier is pulled proximally within the extension tube and the compression ring is thus pulled into contact with the distal end of the extension tube. Continued pulling of the carrier causes the compression ring to be pushed off the assembly onto target tissue, at which point the ring is relaxed to assume a small configuration and clamp the target tissue.

    Abstract: A multiple band endoscopic ligation device comprises a single pull string and a plurality of beads positioned on said pull string and between each successive band. The device is configured to be coupled to the distal end of an endoscope and is used to deploy multiple elastic bands around target tissues to be ligated. The device includes a tapered cylindrical body about which a plurality of elastic bands are stretched and positioned. The pull string includes multiple sets of two beads fixed to the string wherein one bead is placed directly behind and in contact with the other. The string is wrapped around the device's body and under each band such that at least one pair of beads is positioned between the elastic bands and one pair of beads is positioned proximally to the most proximal band. As the string is pulled, the beads push the bands sequentially off the distal end of the device and around a tissue to be ligated.

  • Publication number: 20140081294
    Abstract: A ligating apparatus and method. One embodiment includes a barrel-shaped ligator attached to the penetrating end of a structure, such as an endoscope, and cord pulling assembly at the opposed end of the structure. In the case of use with an endoscope, a pullable cord is wound on the cord pulling assembly and then extends through a working channel in the endoscope to penetrate the ligator. The barrel-shaped ligator is coaxial with the penetrating end of the endoscope, and a practitioner can look through the operating end of the endoscope and see through the endoscope and ligator to observe flesh, for example, in front of the ligating end of the ligator. The ligator includes coaxial inner and outer barrels that rotate with respect to each other upon pulling of the cord by the cord pulling assembly. This relative rotation causes one barrel to move laterally with respect to the other barrel and eject a ligature from the ligating end of the ligator.
