FIELD: medicine.
SUBSTANCE: invention refers to medicine, particularly to vascular and endovascular surgery, and can be used to assess the state of an isolated aneurismal sac after a stent graft implantation by measuring a pressure inside the sac, as well as for introducing drugs into the blood vessel aneurism as it may be required. The device for pressure measurement in the isolated cavity of the aneurismal sac and for drug introduction into the blood vessel aneurism is configured as a hollow tube. The tube has side holes and is configured to reshape when inserted into the aneurism, to fill its inner space circumferentially, to attach by a two-piece hollow tube to a pressure sensor to measure a pressure between the vascular wall and the wall of the stent graft implanted into the blood vessel, as well as to introduce drugs by means of the above two-piece hollow tube. The tube is made of a viscoelastic absorbable material and spiral-shaped.
EFFECT: invention enables solving a set of challenges: saving the manufacturing expenses, simplifying the course of the surgical intervention, measuring the pressure, introducing the drugs, improving the immediate and remote results by ensured thrombosing of the aneurismal sac.
