Abstract

Disclosed is a medical system for short time replacement and repair of a native valve, which comprises an artificial valve (502); and a device for collecting and arranging chordae and/or leaflets to hold and/or stabilize the artificial valve in a desired position, the device comprising: a unit for grasping a plurality of chordae and/or leaflets. The system and/or device allows for fast and easy replacement of a native valve, fast and easy positioning of a temporary artificial valve, and more time for medical personnel to make decisions, prepare and/or perform surgery/medical intervention.

First claim

The invention claimed is:

1. A medical system for short time replacement and repair of a native valve, comprising:
an artificial valve; and
a device for collecting and arranging chordae to hold and/or stabilize said artificial valve in a desired position, said device comprising:
a unit for grasping a plurality of chordae and/or leaflets, wherein said unit is a fluid-fillable balloon, whereby in use, said plurality of chordae is pulled towards the artificial valve by inflation of said unit, creating a temporary space between the chordae and the ventricular wall of the heart.

2. The system of claim 1 , further comprising:
a steerable catheter for delivering said artificial valve; and/or
an annuloplasty device; and/or
a location valve expander; and/or
a clip for locking said chordae in positions towards said artificial valve.

3. The device of claim 1 , wherein said artificial valve is collapsible for delivery and/or expandable upon delivery, and wherein said device is attached to or integrated with said artificial valve.

4. The device of claim 1 , further comprising a clip.

5. The device of claim 4 , wherein said chordae and/or said leaflets are kept in position towards said artificial valve with said clip.

6. The device of claim 4 , wherein said clip is shaped as a helix.

7. A method of delivering an artificial valve for short time replacement of a native valve, such as a mitral valve or an aortic valve, in a heart, said method comprising:
positioning said artificial valve inside said native valve;
pulling a plurality of chordae and/or leaflets together and towards said artificial valve by use of a device for collecting and arranging chordae to hold and/or stabilize said artificial valve in a desired position, said device comprising:
a unit for grasping a plurality of chordae and/or leaflets, wherein said unit is a fluid-fillable balloon, whereby the method comprises:
pulling said plurality of chordae towards the artificial valve by inflation of said unit, creating a temporary space between the chordae and the ventricular wall of the heart.

8. The method of claim 7 , further comprising: deploying a clip to surround said artificial valve and/or to keep said chordae and/or leaflets in position towards said artificial valve.

9. The method of claim 8 further comprising: deploying said clip by pushing it out of a catheter and into position with a pusher.

10. The method of claim 7 , wherein said artificial valve is collapsible for delivery and/or expandable upon delivery.

11. The method of claim 7 , wherein said catheter enters from the left ventricle and goes at least partly into the left atrium for delivery of said artificial valve.

12. The method of claim 11 , wherein said catheter is a two-axis steerable catheter.

13. The method of claim 7 , wherein a catheter enters from the groin and goes via aorta at least partly into the ascending aorta for delivery of said valve.

14. The method of claim 7 , further comprising:
inserting an annuloplasty device; and
positioning said annuloplasty device.

15. The method of claim 14 , wherein inserting of an annuloplasty device is performed after said artificial valve is positioned.

16. The method of claim 14 , further comprising:
removing said artificial valve.

17. The method of claim 16 , wherein said artificial valve is removed after said inserting and positioning of said annuloplasty device.

18. The method of claim 7 , further comprising:
advancing an annuloplasty device into position through said temporary space.
