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

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 and pulling the plurality of chordae towards the device.

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 . A device for collecting and arranging chordae and/or leaflets to hold and/or stabilize an artificial valve in a desired position, said device comprising:
a unit for grasping a plurality of chordae and/or leaflets and pulling the plurality of chordae towards the device.

4 . The device of claim 3 , wherein said unit for grasping a plurality of chordae comprises
a hook and/or a ring and/or a fluid-filled balloon.

5 . The device of claim 3 , 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.

6 . The device of claim 5 , wherein said unit for grasping a plurality of chordae and/or leaflets comprises a plurality of hooks, said hooks being equidistantly distributed exteriorly along said artificial valve.

7 . The device of claim 3 , wherein said chordae and/or said leaflets are collected and arranged towards said artificial valve by rotation of said artificial valve.

8 . The device of claim 3 , wherein said artificial valve is secured to said chordae and said native valve by rotation of said artificial valve.

9 . The device of claim 7 , wherein said rotation of said artificial valve is actuated by rotating a catheter.

10 . The device of claim 3 , further comprising a clip.

11 . The device of claim 10 , wherein said chordae and/or said leaflets are kept in position towards said artificial valve with said clip.

12 . The device of claim 10 , wherein said clip is shaped as a helix.

13 . Use of the medical system of claim 1 for short-term replacement of a native valve and/or for temporary use during beating heart surgery.

14 . Use of the device of claim 3 for short-term replacement of a native valve and/or for temporary use during beating heart surgery.

15 . Use of the device of claim 3 during life saving intervention, intervention in acute leaflet and/or chordate rupture.

16 . 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 and pulling the plurality of chordae towards the device.

17 . The method of claim 16 , 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.

18 . The method of claim 16 , wherein said plurality of chordae and/or leaflets are pulled together by rotation of said artificial valve.

19 . The method of claim 17 , wherein said rotation of said artificial valve is actuated by rotating a catheter.

20 . The method of claim 16 , wherein said artificial valve is collapsible for delivery and/or expandable upon delivery.

21 . The method of claim 16 , wherein said catheter enters from the left ventricle and goes at least partly into the left atrium for delivery of said artificial valve.

22 . The method of claim 16 , wherein said catheter enters from the groin and goes via aorta at least partly into the ascending aorta for delivery of said valve.

23 . The method of claim 16 , further comprising:
inserting an annuloplasty device; and positioning said annuloplasty device.

24 . The method of claim 23 , wherein inserting of an annuloplasty device is performed after said artificial valve is positioned.

25 . The method of claim 23 , further comprising:
removing said artificial valve.

26 . The method of claim 25 , wherein said artificial valve is removed after said inserting and positioning of said annuloplasty device.

27 . The method of claim 16 , further comprising:
creating an additional space between at least two chordae and a ventricular wall of the heart by said pulling a plurality of chordae together.

28 . The method of claim 27 , further comprising:
advancing an annuloplasty device into position through said additional space.

29 . The method of claim 16 , wherein said catheter is a two-axis steerable catheter.

30 . The method of claim 16 , further comprising: deploying said clip by pushing it out of said catheter and into position with a pusher.
