Patent ID: 10052069

Abstract:
The invention relates to medicine, in particular, to vascular and endovascular surgery, and can be used for assessment of the condition of an isolated space of an aneurysmal sac after implantation of a stent-graft by measuring pressure inside the sac, and for administration of drugs to an aneurysm in a blood vessel as far as necessary. The device for measurement pressure in an isolated space of an aneurysmal sac and for administration of drugs to an aneurysm in a blood vessel is made in the form of a hollow tube. The tube has side apertures and is adapted to change a shape when introduced into an aneurysm, and to fill the entire interior space of the aneurysm at its circumference. The tube is also adapted to be connected to a pressure-measuring sensor through a detachable hollow tube to measure pressure between the vessel wall and the wall of a stent-graft implanted to the blood vessel, and to administer drugs through said detachable hollow rube. The tube is made of a viscoelasticity resorbable material and coiled in a spiral form. The invention allows addressing a plurality of problems: cost saving on production of the device, facilitation of an invasion process, measurement of pressure, administration of drugs, improvement of direct and late results by ensuring thrombosing of an aneurysmal sac.
