ENDOVASCULAR BIFURCATION IMPLANTED PROSTHETIC APPLIANCE Russian patent published in 2008 - IPC A61F2/82 

FIELD: medicine.

SUBSTANCE: endovascular bifurcation implanted prosthetic appliance can be used in X-ray-endovascular surgery for restoration of changed parts of clearings of blood vessels, for example, of aneurysm of thoracic part of aorta or abdominal aneurysm. Prosthetic appliance has main case provided with bifurcation in distal part and two legs form of extended polytetrafluoroethylene and strengthened from outside by self-widened metal stenter made of zigzag-curved wire, which form cylindrical surfaces. Prosthetic appliance is made integral and it is provided with envelope of extended polytetrafluoroethylene, which covers metal stenter by two guiding branches - shorter and longer ones, as well as fixing threads for shorter and longer branches. Shorter branch has ring at its proximal end to let longer branch go. There is thread-extender onto distal end. Shorter and longer branches are attached to prosthetic appliance by fixing threads for shorter and longer branches correspondingly by means of loop-shaped easily loosing seam. Fixing thread for longer branch has one its end attached to distal end of leg and it reaches proximal end of main case. Fixing thread of shorter branch is attached close to distal end of leg and it attaches shorter branch until point of bifurcation. Branches are connected higher than point of bifurcation of main case.

EFFECT: prevention of replacement of prosthetic appliance due to complications; simplicity and high comfort of implantation operation.
