	First Claim: Show all 19 claims			We claim: 1. An endovascular device for use within a vascular system comprising: at least one delivery wire having a first resistance; and at least one detachable 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 for the purpose of delivering heat to a fluid within said vascular system at a predetermined location, substantially all of said heat being generated by electrical current flowing flowing within said heating coil rather than within said delivery wire, whereby endovascular thermal treatment is provided within said vascular system.
