Abstract

The invention relates to a device for performing a cutting-balloon intervention that includes a cutting-balloon catheter with an expandable balloon having axially arranged knives, with the cutting-balloon catheter having a pre-mounted stent.

Claims

1-20. -20. (canceled)

21. A device for performing a cutting-balloon intervention on a patient, comprising:

a cutting-balloon catheter with an expandable balloon comprising an axially arranged knive; and

a stent that is pre-mounted to the cutting-balloon catheter.

22. The device as claimed in claim 21, wherein the stent is located in a vicinity of a tip of the cutting-balloon catheter.

23. The device as claimed in claim 21, wherein the cutting-balloon catheter comprises a second expandable balloon on which the stent is positioned or secured.

24. The device as claimed in claim 21, wherein the stent is at least partially self-opening out.

25. The device as claimed in claim 21,

wherein a material of the stent is at least partially a metal, and

wherein the metal is selected from a group consisting of:

high grade steel, nitinol, and shape memory alloy.

26. The device as claimed in claim 21,

wherein a material of the stent is at least partially a bioresorbable material, and

wherein the in bioresorbable material is selected from the group consisting of:

biologic material, magnesium, bio-engineering material, and plastic.

27. The device as claimed in claim 21,

wherein the stent comprises a coating for guiding the cutting-balloon catheter, and

wherein the coating is a nano coating or an active component coating.

28. The device as claimed in claim 21,

wherein the cutting-balloon catheter comprises an integrated unit for image monitoring, and

wherein the integrated unit for image monitoring comprises an OCT sensor or an IVUS sensor.

29. The device as claimed in claim 21,

wherein the cutting-balloon catheter comprises a position sensor system, and

wherein the position sensor system is an electromagnetic sensor system.

30. The device as claimed in claim 21, wherein the cutting-balloon catheter comprises a device for pushing or pulling the cutting-balloon catheter.

31. The device as claimed in claim 21, wherein a physiological sensor is arranged on a tip of the cutting-balloon catheter.

32. The device as claimed in claim 21, wherein the cutting-balloon catheter comprises a coating for screening or reducing a frictional resistance in a vessel of the patient.

33. The device as claimed in claim 21,

wherein the cutting-balloon catheter comprises a separate lumen for injecting a contrast medium, and

wherein the contrast medium is an ultrasound contrast medium.

34. An x-ray apparatus for performing a cutting-balloon intervention on a patient, comprising:

a cutting-balloon catheter with an expandable balloon comprising an axially arranged knive; and

a stent that is pre-mounted to the cutting-balloon catheter.

35. The x-ray apparatus as claimed in claim 34, further comprising an image correcting unit that corrects an image artifact due to the stent.

36. The x-ray apparatus as claimed in claim 34, further comprising a sensor selected from the group consisting of:

an IVUS sensor, an OCT sensor, a position sensor, an ECG sensor, and combinations thereof.

37. The x-ray apparatus as claimed in claim 36, wherein image data recorded by the x-ray apparatus and by the sensors are read out in a time sequence.

38. The x-ray apparatus as claimed in claim 36, wherein an x-ray image data recorded by the x-ray apparatus is combined or overlaid with an image data recoded by the IVUS sensor or the OCT sensor.

39. A method for performing a cutting-balloon intervention on a patient, comprising:

arranging a cutting-balloon catheter with an expandable balloon comprising an axially arranged knive; and

pre-mounting a stent to the cutting-balloon catheter.

40. The method as claimed in claim 39, wherein the stent comprises an active component selected from the group consisting of:

Sirolimus, Paclitaxel, Everolimus, Rapamycin, and FK 506.
