A deployment device for a prosthesis includes a driving assembly, including a driving tube and a driving pin. The deployment device also includes a driven assembly, including a driven tube and a driven pin. The driven pin and the driven tube may be further associated with the prosthesis. The driving tube, the driving pin, the driven tube and the driven pin may all be located coaxially, with the driving pin configured to translate through a cavity in the driving tube and the driven pin configured to translate through a cavity in the driven tube. This configuration allows for a two-stage implantation process for the prosthesis, as the driving tube and driving pin may move together in one stage and may move relative to one another in a second stage.

A surgical port assembly for use with surgical instruments includes a body including an exterior surface and an interior space defined by an interior surface of the body. The surgical port assembly includes a control interface including a plurality of drive members coupled to the body and controllable to apply a force to a different portion of a shaft of an surgical instrument, when the shaft is disposed within the inferior space, to move a distal portion of the surgical instrument to a desired position within a body cavity.

A medical instrument includes a unitary jaw structure having: a connector portion, a first jaw portion flexibly integral with the connector portion, a first arm portion integral with the first jaw portion, and an actuator portion flexibly integral with the first arm portion for causing rotating motion of the first jaw portion upon linear motion of the actuator portion. The medical instrument includes a unitary wrist structure having: a first connector portion having a lower stop surface, a compact flexure integral with the first connector portion, and a second connector portion integral with the compact flexure with the second connector portion having an upper stop surface integral with the compact flexure below the lower stop surface and forming an angle with the lower stop surface.
