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 replacement and/or repair of a native heart valve, comprising;
a catheter,
an artificial valve,
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 clip being deployable from the catheter to surround the artificial valve and to lock the chordae in position towards the artificial valve, and
wherein the clip is shaped as a helix.

2. A medical system according to claim 1 , wherein the helix comprises at least two turns.

3. A medical system according to claim 1 , wherein the helix comprises at least three turns.

4. A medical system according to claim 1 , wherein the artificial valve is expandable and/or collapsible.

5. A medical system according to claim 1 , wherein the clip is a separate piece and not integral with the artificial valve.

6. A medical system according to claim 1 , further comprising a steerable catheter for delivering the artificial valve.

7. A method of delivering an artificial valve for replacement of a native valve in a heart, the method comprises
positioning the artificial valve inside the native valve,
pulling a plurality of chordae and/or leaflets together towards the artificial valve for collecting and arranging the chordae to hold and/or stabilize said artificial valve in a desired position by
deploying a clip from a catheter to surround the artificial valve and to keep the chordae in position towards the artificial valve,
wherein the clip is shaped as a helix.

8. A method according to claim 7 , wherein the clip is rotated into position at the artificial valve.

9. A method according to claim 7 , comprising creating a space between the chordae and a ventricular wall of the heart by pulling the chordae towards the artificial valve.

10. A method according to claim 7 , comprising deploying the clip by pushing the clip out of the catheter and into position with a pusher.

11. A method according to claim 7 , wherein the native valve is a mitral valve.

12. A method according to claim 7 , wherein the native valve is an aortic valve.
