ENDOPROSTHESIS AND DEVICE FOR ITS DELIVERY Russian patent published in 2017 - IPC A61F2/06 A61F2/07 A61F2/24 A61B17/12 

FIELD: medicine.

SUBSTANCE: endoprosthesis, in particular, a vascular or cardiac stent, comprises at least one body. At least partially, thrombogenic elements are located on the outer surface of at least one part of the endoprosthesis body. The endoprosthesis is provided with at least one selectively deactivated retention means holding the thrombogenic elements adjacent to the surface of said body portion. The delivery device comprises the aforementioned endoprosthesis and preferably at least one shell with an endoprosthesis inserted therein adapted to be compressed during delivery and release by relative displacement of the shell and the endoprosthesis. A method for implantation of the above endoprosthesis, particularly into an aneurysmal vascular region or a natural heart valve, includes endoprosthesis placement in the area to isolate the aneurysm from the bloodstream or in the area adjacent to the natural valve, as well as releasing of the thrombogenic elements of the endoprosthesis by placing them at a specific distance from the endoprosthesis surface in the aneurysm cavity.

EFFECT: prevention of the continuation of aneurysm growth and making it possible to use thrombogenic materials easily and without risk to the patient.
