DEVICE FOR ENDOLUMINAL TREATMENT OF BLOOD VESSEL Russian patent published in 2015 - IPC A61B18/24 A61N5/67 

FIELD: medicine.

SUBSTANCE: device for the endoluminal treatment of a blood vessel comprises a flexible wave guide with a light guide tube. The wave guide has an elongated axis, a proximal end with a connector for optical connection to a laser light source, a distal end placed in the blood vessel and comprising an emitting surface for the emission of light from the light source sideways in relation to the elongated axis of the wave guide onto a surrounding vascular wall segment extending within the angular range. The device is provided with a secondary laser light source, a reflected light reception detector, a laser light transparent cone-shaped primary diffuser (1) with laser light deflection and a secondary diffuser (3) extending the laser light coverage area. The primary diffuser (1) is mounted at an optical output of the wave guide between the emitting surface of the wave guide and a sapphire safety cap (2). The secondary diffuser (3) is mounted between the safety cap (2) and the primary diffuser (1). The device also comprises a detachable sterilised protective sheath (4). The protective sheath (4) is made from heat-shrinkage polytetrafluoroethylene, configured as a tube with an ultrasound contrast insert and mounted on the wave guide over the safety cap (2).

EFFECT: using the invention is expected to improve the quality of blood vessel coagulation, eliminating light guide burning and reducing its friction on the blood vessel.
