  • Patent number: 11957350
    Abstract: A device includes an elongated hollow member having an open distal end for receiving tissue therein and at least one exterior groove for loading at least one ligation band thereon. The device also includes a band deployment sleeve slidable over the exterior of the hollow member and configured to move from a radially expanded position to a radially contracted position in which, when the band deployment sleeve slides longitudinally over the hollow member, the distal portion engages the at least one ligation band. A closing sleeve slidable over the exterior of the band deployment sleeve is configured to constrain the distal portion from the radially expanded position into the radially contracted position. Retracting the closing sleeve proximally over the distal portion of the band deployment sleeve releases the distal portion from the radially contracted position into the radially expanded position.

  • Patent number: 11957408
    Abstract: A medical device that includes a handle, a sheath extending from the handle, and a tool within the sheath and movable relative to the sheath. The handle includes an inner body and an outer body disposed over the inner body. The outer body is movable relative to the inner body. The handle includes a first actuator secured to the tool. The first actuator has an actuated state permitting movement of the tool relative to the sheath in response to moving the outer body relative to the inner body. The handle includes a second actuator secured to the sheath. The second actuator has an actuated state permitting movement of the sheath relative to the tool in response to moving the second actuator relative to the outer body. An unactuated state of the first actuator and an unactuated state of the second actuator prevents movement of the tool relative to the sheath.
