Abstract

The present invention relates to a system for introduction of an agent into a blood vessel (G), wherein the system (1) comprises a wire (10) having a proximal end (114, 121) and a distal end (112) as well as lumen (115) extending between these ends, wherein the system is characterized in that a matrix (13) for release of the agent is provided within the lumen (115), wherein the matrix (13) extends over at least part of the length of the wire (10). Thereby an oxygenation system for cerebral vessels can be provided.

Claims

1. System for introduction of an agent into a blood vessel (G), wherein the system (1) comprises a wire (10) having a proximal end (114, 121), a distal end (112) and a lumen (115) extending between these ends, wherein a matrix (13) for release of the agent is provided within the lumen (115), and further wherein the matrix (13) extends over at least part of the length of the wire (10).

2. System according to claim 1, wherein the matrix (13) is arranged in the area of the distal end (114, 121) of the wire (10).

3. System according to claim 1, wherein the matrix (13) extends over the entire length of the wire (10).

4. System according to claim 1, wherein the outer diameter of the wire (10) decreases towards the distal end (114, 121) of the wire (10).

5. System according to claim 1, wherein the wire (10) has a release region (12, 1131) at its distal end, and further wherein in the wire wall at least one release opening (1131) is provided.

6. System according to claim 5, wherein the release area is formed by a spiral (12).

7. System according to claim 1, wherein the matrix (13) consists of a porous plastic.

8. System according to claim 1, wherein the system comprises a connecting device.

9. System according to claim 1, wherein the matrix (13) consists of ePTFE.

10. System according to claim 8, wherein the connecting device is detachably attached at the area of the proximal end (112) of the wire (10) and serves for introduction of the agent into the lumen (115).
