Abstract

The present invention relates to methods of using medical cutting tools for treating aortic septal dissections.

Claims

1. A medical cutting tool comprising:

a catheter having at least one self-expanding displacement element attached to said delivery catheter;

at least one moveable wire having at least one cutting edge incorporated with said catheter, said moveable cutting wire being actuated with an elongate member; and

a housing for said moveable cutting wire attached to said catheter.

2. The medical cutting tool of claim 1 further comprising at least one displacement element having two ends and at least one moveable collar attached to one end of said at least one displacement element;

and

wherein one end of said displacement element is attached to said catheter.

3. The medical cutting tool of claim 2 further comprising a flexible atraumatic end portion.

4. The medical cutting tool of claim 1 further comprising a housing configured to contain a guidewire.

5. A medical cutting tool comprising:

an elongate electrical conductor having a hook-shaped end;

electrical insulation placed on at least a portion of said hook-shaped end such that a portion of said hook-shaped electrical conductor does not have electrical insulation thereon; and

a delivery catheter for said elongate electrical conductor.

6. The medical cutting tool of claim 5 further comprising a radio frequency generator connected to said elongate electrical conductor.

7. The medical cutting tool of claim 5 further comprising at least one displacement element attached to said catheter and said elongate electrical conductor.

8. The medical cutting tool of claim 7 wherein said at least one displacement element is self-expanding.
