Abstract: |
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 are permanently connected to the delivery wires. 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.

RELATED APPLICATIONS
The present application is a divisional application of of U.S. patent application Ser. No. 08/497,294 filed Jun. 30, 1995 now U.S. Pat. No. 5,851,206, which in turn is a continuation-in-part application of U.S. patent application Ser. No. 08/311,508 filed Sep. 23, 1994, now U.S. Pat. No. 5,540,680, and entitled "Improvements in an Endovascular Electrolytically Detachable Wire and Tip for the Formation of Thrombus in Arteries, Veins, Aneurysms, Vascular Malformations, and Arteriouvenous Fistulas", which was a continuation-in-part application of application Ser. No. 08/840,211, filed Feb. 24, 1992, and issued as U.S. Pat. No. 5,354,295, which in turn was a continuation-in-part application of application Ser. 07/492,717, filed Mar. 13, 1990 and issued as U.S. Pat. No. 5,122,136, all of which are incorporated herein by reference as if set forth in their entirety.

First Claim:
Show all 17 claims |
We claim:
1. An improvement in an endovascular device for use within a vascular system comprising:
- at least one elongate, flexible, fully insulated and substantially unsupported delivery wire having a first resistance; and
- at least one elongate, flexible, fully insulated, substantially unsupported, and longitudinally resilient heating coil having a second resistance coupled to said delivery wire, said first resistance being less than said second resistance, wherein said delivery wire and heating coil are both electrically insulated to permit endovascular disposition of said delivery wire and heating coil into said vascular system to deliver heat to blood within said vascular system at a predetermined location, substantially all of said heat being generated by electrical current flowing within said heating coil rather than within said delivery wire,
- whereby endovascular thermal treatment is provided within said vascular system.
