Abstract

The invention relates to a catheter system comprising a totally implantable reservoir for a treating agent, and at least one catheter connected thereto. The reservoir is designed to have a variable volume so that it can be positioned in the tissue by a small cannula needle when its volume is small and can be brought to the required internal volume in situ.

Claims

1. A catheter system comprising a reservoir and at least one catheter attached thereto for applying treating agents, wherein the reservoir is of a variable volume and consists of an extensible and hardenable plastic material.

2. A catheter system according to claim 1, wherein said reservoir is elongated.

3. A catheter system according to claim 1, wherein the wall of said reservoir consists of a material that can be repeatedly punctured.

4. A catheter system according to claim 1, wherein said reservoir is elongated.

5. A catheter system according to claim 1, wherein the wall of said reservoir consists of a material that can be repeatedly punctured.

6. A catheter system comprising:

a reservoir;

at least one catheter attached thereto for applying treating agents, the reservoir being of variable volume; and

a balloon catheter shaped so as to be fittable inside said reservoir.

7. A catheter system according to claim 6, wherein said reservoir is elongated.

8. A catheter system according to claim 6, wherein the wall of said reservoir consists of a material that can be repeatedly punctured.

9. A catheter system comprising:

a reservoir;

at least one catheter attached thereto for applying treating agents, the reservoir being of variable volume;

an extensible metal body arranged within said reservoir; and

a balloon catheter shaped so as to be fittable inside said reservoir and said extensible metal body.

10. A catheter system according to claim 9, wherein said reservoir is elongated.

11. A catheter system according to claim 9, wherein the wall of said reservoir consists of a material that can be repeatedly punctured.
