Thiyagarajan Chelladurai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9814517
    Abstract: A surgical instrument includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position. A trigger assembly is movable between an un-actuated position and an actuated position. An energizable member is selectively movable relative to the jaw members between a first storage position and a first deployed position. At least a portion of the energizable member extends distally from the jaw members in the first deployed position. A selector is operably associated with the trigger assembly and the energizable member. The selector is transitionable between a first state, wherein the energizable member is decoupled from the trigger assembly, and a second state, wherein the energizable member is coupled to the trigger assembly such that movement of the trigger assembly from the un-actuated position to the actuated position effects movement of the energizable member from the storage position to the deployed position.

  • Patent number: 9814516
    Abstract: A surgical instrument includes a housing, a shaft, an end effector assembly disposed at the distal end of the shaft, a deployable assembly movable relative to the end effector assembly between a storage position and a deployed position, and a selector assembly. The selector assembly includes a selector member extending from the housing. The selector member is translatable relative to the housing between a first position and a second position. In the second position of the selector member, the selector member is rotatable relative to the housing for transitioning the selector assembly between a first state, wherein the selector member is decoupled relative to the deployable assembly, and a second state, wherein the selector member is coupled to the deployable assembly such that movement of the selector member from the second position to the first position effects movement of the deployable assembly from the storage position to the deployed position.
