FILLED SHELL FOR SOFT ENDOPROSTHESIS WITH DIFFERENT CLUTCH SURFACES Russian patent published in 2018 - IPC A61F2/12 

FIELD: medicine.

SUBSTANCE: invention relates to medical prostheses. Thoracic endoprosthesis contains a shell having an outer surface, textured for contact with the tissues of the body, on which there is a first bond surface formed by a first cellular structure with open pores, and a second clutch surface formed by a second cellular structure with open pores. Second structure is different from the first one. First and second adhesion surfaces are arranged so as to stimulate, in varying degrees, the ingrowth or adhesion of the tissues at a suitable contact site between the body and the shell. First surface of the clutch, namely the surface on the back side and along the perimeter, has a shallow, matte texture, whereas the second surface of the clutch, namely the face, has a denser texture. Second surface of the clutch is at least one elongated engagement portion made in the form of a strip and with a more embossed texture, ruggedness or roughness than the remaining portions of the front side of the cladding.

EFFECT: technical result is to improve the texturing of the outer surface of the implants.
