DEVICE FOR ENDOVASCULAR PROSTHESIS DELIVERY Russian patent published in 2017 - IPC A61F2/95 

FIELD: medicine.

SUBSTANCE: device contains a tubular element with a distal area, proximal area and an area for connection to the endovascular prosthesis attached to the distal area. The distal area has a porous surface formed by a plurality of circumferential rings, adjacent pairs of which are connected to each other by at least one longitudinal spacer. The porous surface has a gradient of the circumferential width between the longitudinal spacers attached to the opposite sides of one circular ring, decreasing in the direction from the proximal area to the distal area. Each circular ring contains alternating vertices and recesses. At least one longitudinal spacer connects the first recess on the first circular ring with the second recess on the second circular ring, adjacent to the first circular ring. Each of the first circular ring and the second circular ring contains only two pairs of alternating vertices and recesses. The invention has a variable degree of tubular element flexibility from the proximal to the distal area.

EFFECT: increased efficiency.
