摘要:
An aortic valve cutter of the present disclosure has a flexible housing with a central lumen for receiving a guide wire. A high-speed rotating wire is disposed within the housing near an edge of the housing. A trough cut into a side of the housing exposes a portion of the rotating wire such that the rotating wire can be used as a cutter. Two pusher wires are disposed on an opposite side of the housing from the rotating wire. Troughs cut into the side of the housing form openings from which the pusher wires can extend. The pusher wires are staggered with respect to one another in the longitudinal direction. When the pusher wires are advanced, they extend outwardly from the troughs and can be used to stabilize the cutter at the aortic valve and push the cutting wire against the valve on the opposite side.
