摘要 |
A thrombus is generated in an aneurysm, arteriovenous malformation or fistula by means of a catheter having an insulated heating coil coupled to an insulated delivery wire. In one embodiment, two delivery wires are coupled to heating coils to provide a closed circuit. The heating coils may be in the form of a double helix or a single helix in combination with a straight heating coil. The heating coils may be permanently connected to the delivery wires or may be electrolytically or mechanically detached therefrom. Alternatively, a single insulated heating coil may be attached to a single insulated delivery wire with a uninsulated coil attached to the tip of the insulated heating coil. The electrical circuit is then made through the heating coil and non-insulated electrode coil into the vascular system and to a body electrode. A catheter may also be used for heating blood within the vascular system which is directly flowed into a tumoral mass for the purposes of thermal treatment of cancer. <IMAGE> <IMAGE> |
