A balloon catheter for photodynamic therapy (optional)

摘要

The invention relates to medical engineering, in particular to a balloon catheter and can be used in the treatment of malignant neoplasms by photodynamic therapy (PDT).; The technical problem is to increase the effectiveness of treatment by providing a uniform distribution of the laser beam irradiated in the body cavity in all directions.; The stated technical problem is solved in that, according to the proposed utility model, the balloon catheter for photodynamic therapy includes bladder connected thereto tube of transparent material with a tee, inside which is coupled to a source of radiation the fiber optic light pipe, the distal end of the fiber optic lightguide placed end portion of the catheter tube, the inner cavity of which is filled further immersed environment, the distal end of the fiber optic light guide is provided with a lens, bottle rib formed cylindrical or conical, or spherical shape, the bladder wall formed with a variable thickness.; The technical result consists in providing uniform illumination of the surrounding tissue of the body cavity irradiated due to the uniform distribution of the laser beam in all directions.
