Abstract

The invention relates to a catheter device for treating a blockage of a vessel, with the catheter device featuring a treatment catheter for treating the vessel blockage which is embodied as an integrated unit with front-mounted stent.

Claims

1. A catheter device for treating a blockage of a vessel of a patient, comprising:

a treatment catheter;

a stent that is mounted in a tip of the treatment catheter,

wherein the tip-mounted stent and the treatment catheter are configured as an integrated unit,

wherein the treatment catheter consists of an integrated image monitoring system,

wherein the image monitoring system comprises an Optical Coherence Tomography (OCT) catheter and an Intravascular Ultrasound (IVUS) catheter,

wherein an image sensor of the OCT catheter is arranged in front of or behind an image sensor of the IVUS catheter in a longitudinal direction of the catheter device,

wherein the catheter device further comprises;

a transparent exit area arranged on a catheter shell of the treatment catheter or a drive shaft of the OCT or IVUS catheter for passing through an ultrasound wave of the IVUS catheter or a light of the OCT catheter,

a hollow flexible drive shaft is provided in an inner area of the catheter shell within which a signal line of the OCT or the IVUS catheter is routed, and

wherein the stent is arranged on an expandable balloon located in the tip of the treatment catheter that unfolds the stent, or

wherein the stent is at least partly self-unfolding.

2. The catheter device as claimed in claim 1,

wherein a material of the stent comprises metal or bioabsorbable material,

wherein the metal is selected from the group consisting of:

a stainless steel, a nitinol, and a memory-metal alloy, and

wherein the bioabsorbable material is selected from the group consisting of;

a biological material, a magnesium material, a bio-engineering material, and a plastic.

3. The catheter device as claimed in claim 1,

wherein the stent comprises a coating,

wherein the coating is a nano coating or a drug agent coating, and

wherein the drug agent coating is selected from the group consisting of:

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

4. The catheter device as claimed in claim 1,

wherein:

the treatment catheter is a chronic total occlusion catheter for treating a complete vessel blockage, and

the chronic total occlusion catheter is a pincer-type catheter.

5. The catheter device as claimed in claim 1,

wherein the Optical Coherence Tomography or the intravascular ultrasound catheter or the drive shaft is ratable.

6. The catheter device as claimed in claim 5,

wherein an image sensor of the Optical Coherence Tomography or the Intravascular Ultrasound catheter is arranged in front of or behind a treatment unit of the treatment catheter,

wherein the treatment unit comprises an opening for passing through the drive shaft or the signal line or the image sensor of the Optical Coherence Tomography or the Intravascular Ultrasound catheter, and

wherein the treatment unit is selected from the group consisting of:

a pincer, a coil, and a laser lens.

7. The catheter device as claimed in claim 1, wherein a three-dimensional image of the vessel is captured by rotating and simultaneously pulling or pushing the Optical Coherence Tomography or the Intravascular Ultrasound catheter.

8. The catheter device as claimed in claim 1,

wherein the treatment catheter comprises a position sensor system,

wherein the position sensor system is an electromagnetic system or an ultrasound-based system comprising a position sensor, and

wherein the position sensor is arranged in an area of a tip of the catheter device.

9. The catheter device as claimed in claim 1, wherein the catheter device is:

mechanically or magnetically automatically navigated,

automatically introduced into the vessel or removed from the vessel, and

coated by a coating for screening a magnetic interference or for improving a guidance of the catheter device in the vessel.

10. The catheter device as claimed in claim 1, further comprising:

a movement sensor for detecting a movement of the patient, and

a physiological sensor located at a tip of the catheter device for detecting a physiological status of the patient.

11. The catheter device as claimed in claim 1, further comprising a lumen for injecting a contrast medium or a flushing fluid into the vessel.

12. The catheter device as claimed in claim 1, wherein the image sensor of the Optical Coherence Tomography catheter and the image sensor of the Intravascular Ultrasound catheter rotate within a catheter shell of the treatment catheter without rotating the catheter shell of the treatment catheter.
