Abstract

A method for repairing a diseased or damaged section of an aorta (i) introduces an intraluminal directing device from a remote access site to a location within a prosthesis at a target site in an aorta where the diseased or damaged section exists, the intraluminal directing device including a deflectable distal region; (ii) establishes a path to a desired fastening site on the prosthesis by manipulating the intraluminal directing device within the prosthesis to orient the distal region with respect to the desired fastening site; (iii) introduces from an intraluminal fastener applier, that is introduced along the path established in (ii), at least one tissue-piercing fastener into tissue at the desired fastening site to anchor the prosthesis; (iv) establishes a path to a different desired fastening site on the prosthesis by manipulating the intraluminal directing device within the prosthesis to orient the distal region with respect to the different desired fastening site; (v) introduces from an intraluminal fastener applier, that is introduced through the path established in (iv), at least one tissue-piercing fastener into tissue at the different desired fastening site to further anchor the prosthesis; and (vi) repeats (iv) and (v) until a desired plurality of tissue-piercing fasteners are introduced into tissue to anchor the prosthesis.

Claims

1. A method for repairing a diseased or damaged section of an aorta comprising:

(i) introducing an intraluminal directing device from a remote access site to a location within a prosthesis at a target site in an aorta where the diseased or damaged section exists, the intraluminal directing device including a deflectable distal region;

(ii) establishing a path to a desired fastening site on the prosthesis by manipulating the intraluminal directing device within the prosthesis to orient the distal region with respect to the desired fastening site;

(iii) introducing from an intraluminal fastener applier, that is introduced along the path established in (ii), at least one tissue-piercing fastener into tissue at the desired fastening site to anchor the prosthesis;

(iv) establishing a path to a different desired fastening site on the prosthesis by manipulating the intraluminal directing device within the prosthesis to orient the distal region with respect to the different desired fastening site;

(v) introducing from an intraluminal fastener applier, that is introduced through the path established in (iv), at least one tissue-piercing fastener into tissue at the different desired fastening site to further anchor the prosthesis; and

(vi) repeating (iv) and (v) until a desired plurality of tissue-piercing fasteners are introduced into tissue to anchor the prosthesis.

2. A method according to claim 1

wherein the prosthesis includes at least one self-expanding scaffold, and

wherein (i) comprises releasing the prosthesis from constraint to permit the at least one scaffold of the prosthesis to self-expand at the target site.

3. A method according to claim 1

wherein the prosthesis includes at least one malleable scaffold, and

wherein (i) comprises applying a radially expansive force within the prosthesis to cause expansion of the at least one scaffold.

4. A method according to claim 1

wherein at least one of the tissue-piercing fasteners comprises a helical tissue-piercing fastener.

5. A method according to claim 1

wherein at least one of the tissue-piercing fasteners comprises a fastener that pierces tissue in response to rotation;

and

wherein (iii) and/or (v) includes rotating the fastener with a rotary driver.

6. A method according to claim 1

wherein the desired plurality of tissue-piercing fasteners are introduced in a circumferentially spaced-apart pattern to anchor the prosthesis.

7. A method according to claim 1

wherein (ii) includes rotating the intraluminal directing device and/or deflecting the distal region.

8. A method according to claim 1

wherein the intraluminal directing device includes a passage, and

wherein (iii) and (v) includes introducing an intraluminal fastener applier to the desired fastening site through the passage.

9. A method according to claim 8

wherein the passage comprises an interior lumen.
