PROBLEM TO BE SOLVED: To provide a percutaneous intravascular blood vessel formation device which is appropriately arranged to capture embolus particles that are discharged in blood flow when carrying out blood vessel formation treatment.SOLUTION: A percutaneous intravascular blood vessel formation device 10 includes an embolic filter 20 mounted on the axis of a catheter 12 at a position closer to a tip end side than a blood vessel formation balloon 18. The filter is downstream of a blocked portion, the embolic filter is normally folded to the axis of the catheter, and the introduction and retreat of the device into/from an operation region is made easy. When the blood vessel formation balloon is appropriately arranged, a means that is operatively associated with the embolic filter actuates, makes the filter rise, and arranges a filter mesh to cover the lumen of the blood vessel. |
