Abstract:
A catheter for disposing radioactive material at a selected position in a blood vessel over a guidewire, said catheter comprising:a flexible tubular body having a radiation lumen;a port formed at a proximal end of said radiation lumen for receiving a radiation source;a sealed distal end formed on said radiation lumen to retain radioactive material within said radiation lumen; anda guidewire channel formed on a distal portion of said tubular body for receiving a guidewire, said guidewire channel having a distal end and a proximal end;wherein said proximal end of said radiation lumen extends proximally beyond said proximal end of said guidewire channel by a length sufficient to allow said port on said radiation lumen to be manipulated in a non-sterile field of an operating room, while said proximal end of said guidewire channel remains in a sterile field.
