1. A carotid shunt device, comprising:
- a tube having a first end, a second end, a first lumen, a second lumen and a third lumen, wherein said first and second lumens are tipped at said first and second ends to stop fluid communication of said first and second lumens beyond said first and second ends;
a first balloon disposed proximate said first end, said balloon being bonded to the exterior of said tube and being in fluid communication with said first lumen;
a second balloon disposed proximate said second end, said second balloon being bonded to the exterior of said tube and being in fluid communication with said first lumen, wherein said first lumen is in fluid communication with an inflation source; and
an illumination member comprising an elongate light transmitting core adapted to transmit light from a light source input to an illumination output, said illumination output being disposed on a side thereof, a cladding substantially surrounding said core and being adapted to confine said light substantially therewithin, said core being coupled to the light source to permit injection of illuminating light into said core, said core being at least partly exposed at said illumination output, to permit said illuminating light to escape laterally from said core, wherein said illumination output is at an end of said light transmission member, wherein said light transmitting core extends a predetermined distance beyond said cladding at said illumination output, and wherein said illumination output is disposed proximate said first balloon, between said first balloon and said second balloon.

Abstract
A lighted catheter device employing an optical fiber having a core and a cladding, the cladding providing internal reflection, the fiber being substantially without the cladding at an end portion to permit light to escape laterally thereat, for illumination in a catheter device. A lighted carotid shunt, a lighted occluder incorporating the fiber and lateral illumination method are described.

8. A method of providing lateral illumination in a carotid shunt device, comprising the steps of:
-
providing an illumination member comprising an elongate light transmitting core adapted to transmit light from a light source input to an illumination output, said illumination output being disposed on a side thereof, a cladding substantially surrounding said core and being adapted to confine said light substantially therewithin, said core being coupled to the light source to permit injection of illuminating light into said core, said core being at least partly exposed at said illumination output, to permit said illuminating light to escape laterally from said core; inserting said illumination output into a lumen of a carotid shunt device; inserting said carotid shunt device in a carotid artery of a patient; and positioning said illumination output in said lumen at a selected location in said device so that said illumination output is disposed to illuminate laterally a selected portion of said carotid artery. - View Dependent Claims (9)

10. A method of providing lateral illumination in an occluder device, comprising the steps of:
-
providing an illumination member comprising an elongate light transmitting core adapted to transmit light from a light source input to an illumination output, said illumination output being disposed on a side thereof, a cladding substantially surrounding said core and being adapted to confine said light substantially therewithin, said core being exposed at said light source input to permit injection of illuminating light into said core, said core being at least partly exposed at said illumination output, to permit said illuminating light to escape laterally from said core; inserting said illumination output into a lumen of an occluder device; inserting said occluder device in a vessel of a patient; and positioning said illumination output in said lumen at a selected location in said device so that said illumination output is disposed to illuminate laterally a selected portion of said vessel. - View Dependent Claims (11)
