USING A CATHETER TO CREATE AN ISOLATED AREA IN THE HOLLOW ORGAN OF A MAMMAL FOR TREATING DAMAGE TO THE WALL OF THE JEONUM OR ILEUM (OPTIONS) Russian patent published in 2023 - IPC A61M25/10 

FIELD: medicine.

SUBSTANCE: group of inventions relates to the use of a catheter for creating an isolated area in a hollow organ of a mammal for the treatment of damage to the wall of the jejunum or ileum. In accordance with the first option, for the treatment of damage to the wall of the jejunum or ileum, a catheter is used, designed to create an isolated area in the hollow organ of a mammal and containing an elongated body configured to be installed in the lumen of the hollow organ of a mammal and equipped with two balloons configured to inflate ensuring the possibility of creating an isolated space of a hollow organ between them. In the elongated body, a functional channel passes with a functional hole made in the elongated body between the cylinders. The functional channel provides the possibility of creating a negative pressure in the isolated space with the possibility of taking a fluid or gaseous medium from it through the functional hole or the possibility of supplying a medical fluid or gaseous medium to the isolated space through the functional hole. In the elongated body, another channel passes, provided at opposite ends, respectively, with inlet and outlet openings made in the elongated body outside its part limited by the cylinders. In accordance with the second option, for the treatment of damage to the wall of the jejunum or ileum, a catheter is used, designed to create an isolated area in the hollow organ of a mammal, in which, in addition to the above, the elongated body is equipped with a mesh or sheath made permeable to a fluid and/or gaseous medium, and the mesh or sheath at least partially encloses the portion of the catheter defined by the balloons to cover the functional opening and is attached to or encloses the balloons such that their inflation allows the mesh or sheath to be stretched. In accordance with the third option, for the treatment of damage to the wall of the jejunum or ileum, a catheter is used, designed to create an isolated area in the hollow organ of a mammal, in which, in addition to the first option described above, a functional opening is located between two annular enclosing projections with which the body of the catheter is equipped between the balloons.

EFFECT: in the first, second and third variants of the invention, the catheter used to create an isolated area in the hollow organ of a mammal provides a technical result consisting in preventing or eliminating the possibility of the formation of congestive and/or inflammatory processes in the hollow organ in the form of the abdominal esophagus, jejunum, ileum, caecum or colon due, in particular, to the accumulation in this hollow organ of mucus and other biological contents specific to said hollow organ outside one of the inflated insulating cylinders.
