Stent positioning system
First Claim
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.

Abstract
There is provided a stent positioning system, including an inflatable balloon (22) for expanding a stent, the balloon, in its collapsed state, fitting into and being adapted to carry the 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 the major vessel and prior to the expansion of the stent, and mechanical means for changing the shape of the stent locator means; wherein the change of shape enables the locator means (14) to abut the interior wall surface, thereby ensuring correct apposition between the stent and the ostium of the smaller blood vessel.
