| 摘要 |
A tunneling device is provided which includes a substantially rigid rod, an energy emitting part at a distal end of the rod, a catheter holding part at a proximal end of the rod, an energy source connected to the energy emitting part, and a control section for activating the energy source to transmit energy to the energy emitting part, so as to cause the energy emitting part to emit cutting and/or cauterizing energy. The substantially rigid rod is adapted to be guided through body tissue while the energy source is active so as to facilitate movement and control of the guided rod.
