Abstract

Methods and apparatuses for positioning a radiation source in vivo relative to radio-opaque markers on a catheter that delineate a therapeutic treatment length so that a therapeutic dose of radiation is delivered along the therapeutic treatment length.

Claims

1. A radioactive source comprising:

a distal end;

a proximal end;

at least a first marker, a second marker, and a third marker located between said distal end and said proximal end, said first marker and said second marker being spaced apart so as to define the therapeutic dose region of the source; and

said third marker being located at said distal end.

2. A radioactive source comprising:

a distal end;

a proximal end;

at least a first marker, a second marker, and a third marker located between said distal end and said proximal end, said first marker and said second marker being spaced apart so as to define the therapeutic dose region of the source; and

said third marker being located at said proximal end.
