PURPOSE: An apparatus fixing stents inside of blood vessel to be grafted in organism on balloon catheter by constant twist, is provided which reduces expansion of stents due to balloon catheter by using variable method, and weakening by fixing method on stents. CONSTITUTION: An apparatus to fix stents on balloon comprises: a first clamping part(16) which is a recess to have proper size for receiving stents crimping sleeve(12); a second clamping part(18) which is a recess(7) to have proper size receiving crimping sleeve; the recess(6) of first clamping part and the recess(9) of second clamping part which limits vertical stents crimping sleeve channel(10) having variable sectional area diameter; the first clamping part(16) and the second clamping part which is proper to move to first position at first direction and to second position at second direction toward each other, to add pressure stents to crimping sleeve arranged in the vertical stents crimping sleeve channel(10) selectively; recess of clamping part(6, 9) which has proper size to let vertical stents crimping sleeve channel(10) and has sectional area diameter with the shape of round in the second position; stents crimping sleeve(12) arranged in the crimping sleeve channel, which has first end, second end, outer surface and inner surface, and limits vertical stents crimping bore; the inside diameter of vertical stents crimping which is variable sectional area diameter with the shape of round selectively and has proper size to receive balloon catheter with stents. |
