Abstract

The invention relates to a process for administering a medication in a blood vessel using a balloon catheter with a balloon which has at least one flank. An inflow direction of the medication is established (i.e., takes place) at an angle α from 0° to 89°, the angle α being formed from the flow direction of the blood in the blood vessel and the flank of the balloon.

Claims

1. Process for administering a medication in a blood vessel using a balloon catheter with a balloon which has at least one flank, comprising:

establishing an inflow direction P of medication at an angle α

from 0 °

to 89°

, the angle α

being formed from a flow direction Q of blood in the blood vessel and the flank of the balloon.

2. Process for administration of a medication as claimed in claim 1, wherein the angle α

can be adjusted depending on an application and/or type of medication.

3. Process as claimed in claim 2, wherein the catheter arrangement is configured specifically for a substance to be administered.

4. Process as claimed in claim 1, wherein an overall cross section of perforations are made such that the balloons 4 can be unfolded and inflated in a dumbbell shape.

5. Catheter arrangement for administering a medication in a blood vessel comprising:

a balloon catheter with a balloon which has at least one flank; and

an additional lumen with an open end located between a distal end of the balloon and a proximal end of the adjacent balloon, and which points into the treatment space.

6. Catheter arrangement as claimed in claim 5, comprising:

perforations located both on the proximal end and on the distal end of the catheter arrangement.

7. Catheter arrangement as claimed in claim 5, wherein the least one flank of the balloon has perforations for administering a medication.

8. Catheter arrangement as claimed in claim 5, wherein the flank and the flow direction Q of the blood form an angle α

, the angle being 0°

to 89°

.
