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.

Abstract: A power supply assembly for converting input power into desired output power comprises a plurality of printed circuit boards each having oppositely facing front and back major surfaces. The back major surfaces of the first and second circuit boards are substantially devoid of the electrical components. The power supply assembly further includes a heat sink disposed adjacent to the first and the second circuit boards, an electrically conducting spline member, which is disposed between the first and second circuit boards, being attached to the heat sink, and a plurality of connectors electrically connecting the first and second circuit boards.
