Abstract

A protective sleeve for a balloon catheter includes an insertion aid for a guide wire. The insertion aid is integrated in the protective sleeve at a distal end of the protective sleeve. In addition, a balloon catheter includes a protective sleeve which at least partially surrounds a balloon. An insertion aid for a guide wire is integrated in the distal end of the protective sleeve.

Claims

1. A balloon catheter comprising a balloon and a protective sleeve which at least partially surrounds the balloon, the balloon catheter further comprising an insertion aid for a guide wire, the insertion aid being integrated in a distal end of the protective sleeve.

2. The balloon catheter as claimed in claim 1, comprising an opening for insertion of the guide wire into an interior of the balloon catheter, the opening provided distally on the insertion aid.

3. The balloon catheter as claimed in claim 1, wherein the insertion aid has a duct-like or tubular design, and wherein the insertion aid widens like a funnel in a direction of the opening provided at the distal end.

4. The balloon catheter as claimed in claim 1, wherein a recess is configured at a distal end of the insertion aid, the recess forming a trough or an open duct.

5. The balloon catheter as claimed in claim 4, wherein the recess has a cross-sectional surface area in a shape of a segment of a circle, or has a V-shaped cross-sectional surface area.

6. The balloon catheter as claimed in claim 4, wherein a cross-sectional surface area of the recess increases toward the distal end of the insertion aid.

7. The balloon catheter as claimed in claim 4, wherein a cross-sectional surface area of the recess is flush, at its proximal end, with the opening in the insertion aid.

8. The balloon catheter as claimed in claim 4, wherein the recess is coded in order to improve discernibility of the recess to the eye.

9. The balloon catheter as claimed in claim 8, wherein the coding is provided on an inner face of the recess.

10. The balloon catheter as claimed in claim 1, wherein the protective sleeve has, proximally adjacent to the insertion aid, at least one area that is flattened in relation to a shape of a remainder of the protective sleeve.

11. The balloon catheter as claimed in claim 1, wherein the insertion aid widens proximally like a funnel, in order to receive and secure the catheter in the insertion aid.

12. The balloon catheter as claimed in claim 1, wherein the protective sleeve comprises a section for facilitating removal of the protective sleeve.

13. The balloon catheter as claimed in claim 12, wherein the section is in the form of at least one predetermined breaking point, at least one perforation and/or at least one incision in the protective sleeve.

14. The balloon catheter as claimed in claim 12, wherein the section comprises at least one handle for removal of the protective sleeve.

19. The balloon catheter of claim 1 further comprising a stent, wherein the protective sleeve at least partially surrounds the stent.

15. A protective sleeve for a balloon catheter comprising a balloon, the protective sleeve configured to at least partially surround the balloon, wherein an insertion aid for a guide wire is integrated in the protective sleeve.

20. The protective sleeve of claim 15, wherein the protective sleeve is configured to at least partially surround a stent on the balloon catheter.

16. (canceled)

17. A method for inserting a guide wire into an interior of a balloon catheter, the method comprising the steps of:

providing a balloon catheter, the balloon catheter having a protective sleeve which at least partially surrounds the balloon, wherein an insertion aid is integrated in a distal end of the protective sleeve; and

inserting the guide wire distally into the protective sleeve.

18. The method as claimed in claim 17, wherein a recess is configured at a distal end of the insertion aid, or is integrally formed on the insertion aid, the recess forming a trough or an open duct.
