<P>PROBLEM TO BE SOLVED: To provide a biological organ dilator implement for inhibiting a movement and a release of a stent mounted on a balloon enough, and having less damage of the balloon during mounting the stent. <P>SOLUTION: A biological organ dilator implement 1 has a balloon catheter 2 and a stent 10 mounted on a balloon 3. A plurality of stents are arranged to the axial direction, and adjacent annular bodies 11 are connected with joint sections 12, 13. The joint section 12 connects between the annular body 11a being odd-numbered from the tip end of the stent 10 and the even-numbered annular body 11b, and it has a first morphological sloping recessed section 22 inside having an inner surface sloping to the rear end of the stent. The joint section 13 connecting between the even-numbered annular body 11b and the odd-numbered annular body 11a has a second morphological sloping recessed section 23 inside having an inner surface sloping opposite to the first morphological sloping recessed section 22. One part of the balloon 3 intrudes in the first and second morphological sloping recessed sections. <P>COPYRIGHT: (C)2011,JPO&INPIT |
