    • A tool for treating a target vessel may include a longitudinally elongated anvil, a channel defined substantially longitudinally in the anvil, and a knife rotatable from a stowed position substantially completely within the channel to an active position in which at least part of the knife extends upward out of the channel, whereby rotation of the knife from the stowed position to the active position incises the target vessel from the inside out. A method of treating a target vessel having a wall may include providing a longitudinally elongated anvil, a channel defined substantially longitudinally in the anvil, and a knife rotatable into and out of the channel; rotating the knife from a stowed position substantially completely within the channel to an active position in which at least part of the knife extends upward out of the channel, wherein the rotating causes the knife to penetrate through the wall of the target vessel; translating the knife along the anvil to create an incision having a length; and rotating the knife from the active position to a withdrawal position substantially completely within the channel, wherein the rotating is in the same direction as the rotating the knife from the stowed position to the active position.
