FIELD: medicine.SUBSTANCE: group of inventions refers to medicine. An apparatus comprises: a flexible wave guide with a long axis, a proximal end optically connected with an emitter, a distal end placed in a blood vessel and comprising an emitting surface producing from the emitter towards the long axis of the wave guide on a surrounding vascular wall region extending within the angular range; there are also provided enclosing assemblies comprising the emitters and generating a gas interface to refract the laser light towards the long axis of the wave guide. A version of the enclosing assembly is a lid rigidly attached to the wave guide, sealed and transparent to the laser light. The method for endoluminal therapy of a blood vessel involves: introducing the wave guide; transmitting the laser light through the wave guide; emitting the laser light simultaneously towards the surrounding vascular wall region extending within the angular range approximately of 360°.EFFECT: using the given group of inventions enables extending the range of techniques and improving the safety and efficacy of the endoluminal laser ablation.23 cl, 11 dwg |
