## Abstract

A system for treating aortic dissection includes a sinotubular junction magnetic array having a first plurality of magnetic elements, a counter-magnetic array having a second plurality of magnetic elements, and an ascending aortic stent graft comprising a third plurality of magnetic elements. A method for treating aortic dissection includes the steps of positioning a sinotubular junction magnetic array at the sinotubular junction, advancing counter magnetic constructs from the femoral vein and positioning them in the right atrium, expanding the sinotubular junction ring at a target position, advancing the counter magnetic array to form an at least partial circumferential seal, and advancing and positioning an ascending magnetic graft within an interior of the sinotubular junction magnetic array. A system for treating aortic dissection, a fixation device for anchoring an ascending aortic stent graft, and a transcatheter device for treating aortic dissection are also described.

## Claims

### Claim 1

A method for treating aortic dissection comprising:
providing a system comprising:
a sinotubular junction magnetic array configured into the shape of a ring having a first plurality of magnetic elements,
a counter-magnetic array having a second plurality of magnetic elements, and
an ascending aortic stent graft comprising a third plurality of magnetic elements;
positioning the sinotubular junction magnetic array at a sinotubular junction;
advancing counter magnetic constructs from the femoral vein and positioning them in the right atrium adjacent to the sinotubular junction;
expanding the sinotubular junction magnetic array at a target position using magnetic forces;
advancing the counter magnetic array as one of the counter magnetic constructs used to form an at least partial circumferential seal; and
advancing and positioning the ascending aortic stent graft within an interior of the sinotubular junction magnetic array.

### Claim 2 (depends on 1)

The method of claim 1, wherein the poles of the first plurality of magnetic elements are configured to correspond with the poles of the second plurality of magnetic elements.

### Claim 3 (depends on 1)

The method of claim 1, wherein the ascending aortic stent graft comprises a plurality of extension wings.

### Claim 4 (depends on 3)

The method of claim 3, wherein the plurality of extension wings comprises three extension wings equally spaced apart.

### Claim 5 (depends on 1)

The method of claim 1, wherein the sinotubular junction magnetic array comprises a lumen.

### Claim 6 (depends on 1)

The method of claim 1, wherein the ascending aortic stent graft comprises a plurality of extension wings.

### Claim 7 (depends on 6)

The method of claim 6, wherein the plurality of extension wings comprises three wings equally spaced apart.
