1. A stent positioning system, comprising:

  • an inflatable balloon for expanding a stent, said balloon, in its collapsed state, fitting into and being adapted to carry said stent in its pre-expanded condition;

    stent locator means slidably accommodated in a guide catheter and adapted to change its shape prior to making contact with the interior wall surface of a major blood vessel in the ostial region of a smaller blood vessel branching off from said major vessel and prior to the expansion of said stent, and mechanical means for changing the shape of said stent locator means;

    wherein the change of shape enables said locator means to abut said interior wall surface, thereby ensuring correct apposition between the stent and the ostium of said smaller blood vessel.
