Abstract
An endovascular treatment method for causing closure of a blood vessel is provided. The method includes inserting into a blood vessel an optical fiber having a core through which a laser light travels and a spacer sleeve arranged around a distal portion of the core. A distal end of the core defines an enlarged light emitting face, which advantageously provides substantially lower power density while providing the same amount of total energy during a treatment session. After the insertion, laser light is applied through the light emitting face while the inserted optical fiber and spacer sleeve are longitudinally moved. The spacer sleeve positions the light emitting face away from an inner wall of the blood vessel and application of the laser light causes closure of the blood vessel.
