1. A tunneling device for creating a path for a catheter or graft, comprising:
- a substantially rigid rod;
an energy emitting part at a distal 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;
wherein 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.

Abstract
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.

23. A tunneling device for creating a path for a catheter or graft, comprising:
-
first and second metallic rods which are (i) attached at a proximal connection point and at a distal connection point, (ii) separated by insulating material except at the connection points, and (iii) insulated on an external surface thereof except at a distal end of said first and second rods;
a catheter holding part at a proximal end of the rod;
an energy source connected to the rod; and
a control section for activating the energy source to transmit energy to the rod, so as to cause the distal end of the rod to emit cutting and/or cauterizing energy;
wherein the connected rods are adapted to be guided through body tissue while the energy source is active so as to facilitate movement and control of the guided connected rods.
