  • Publication number: 20190247083
    Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, an articulation drive assembly, and a locking feature. The shaft extends distally from the body assembly. The waveguide comprises a flexible portion. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis of the shaft. The articulation drive assembly comprises an actuator. The actuator is movable relative to the body assembly to drive articulation of the articulation section. The locking feature is in communication with the actuator. The locking feature is movable between an unlocked state and a locked state. The locking feature is configured to permit movement of the actuator relative to the body assembly in the unlocked state. The locking feature is configured to prevent movement of the actuator relative to the body assembly in the locked state.

  • Patent number: 10376265
    Abstract: Devices are used to modify a metabolic pathway of a digestive system by creating a pathway within the intestinal tract through an anastomosis between a proximal location within the intestinal tract and a distal location within the intestinal tract. An anastomosis compression assembly includes a first portion and a second portion, each including two or more segments securely fixed together by a pair of degradable joining members, and each further including interlocking mechanisms. The first portion and second portion are configured to be coupled together from different locations within the intestinal tract by the application of force. Once aligned, the first and second portions are securely attached to one another by engaging their respective interlocking mechanisms. After completion of the anastomosis procedure, the degradable links degrade and separate the anastomosis compression assembly into smaller fragments for ease of passage through the patient's intestinal tract.
