Abstract

The appliance comprises radioactive radiation means formed by a coiled filament of radioactive material a proximal part of which is formed by a coiled filament having a pitch larger than that of the coiled filament. Coiled filament is for meshing with thread formed at the distal end of a guidewire.

Claims

1. A medical device comprising a radioactive coil and an elongate member having a distal portion, wherein the radioactive coil is at least partially threaded about the distal portion of the elongate member.

2. The device of claim 1 wherein the coil is at least partially removably threaded about the distal portion of the elongate member.

3. The medical device of claim 1 wherein the elongate member is a guidewire.

4. The medical device of claim 1 wherein the radioactive coil includes 90 Yttrium.

5. The medical device of claim 4 wherein the radioactive coil is covered by Titanium.

6. A medical device comprising an elongate member having a distal portion and a discrete radiation source, wherein the elongate member distal portion and the radiation source are adapted for removable attachment to one another.

7. The medical device of claim 6 wherein the discrete radiation source is a coil.

8. The medical device of claim 6 wherein the elongate member is a guidewire.

9. The medical device of claim 6 wherein the radiation source includes 90 Yttrium.

10. The guidewire of claim 9 wherein the radiation source is covered by Titanium.
