METHOD AND CATHETER DEVICE, EQUIPPED WITH INFLATABLE BALLOON, FOR DYNAMIC REGULATION OF VENOUS RETURN

摘要

FIELD: medicine.;SUBSTANCE: group of inventions relates to medicine, namely to cardiology and cardiac surgery, and can be used in the treatment of patients with congestive heart failure. Claimed is a catheter device for the dynamic regulation of the venous return, including a bidirectional catheter, which has a proximal end, an inflatable balloon, which is installed on the catheter. The said balloon is made of a flexible material, extending to increase the balloon volume. The catheter has an external surface, which includes slots, directed parallel to its longitudinal axis, and a distal screw, fixing the catheter on the inferior vena cava wall. Also claimed is a method of installing the catheter device, which includes the introduction of the bidirectional catheter with the inflatable balloon through the subclavicular vein. The catheter is fixed on the cava vena wall by means of the distal screw. The balloon is fixed near the vena cava outlet with its further pumping with physiological solution or glucose solution.;EFFECT: group of inventions provides the mechanical regulation of an increased venous return flow in the patients with simultaneous simplicity of the catheter device application.;9 cl, 4 dwg, 2 ex
