Abstract

Methods, apparatus, and systems for repairing defective occlusions are provided. One embodiment includes an elongate body having a first lumen extending from a proximal end toward a distal end of the elongate body. An elongate structure, having a lumen extending from a proximal end toward a distal end of the elongate structure, is extendably and rotatably positioned at least partially within the first lumen of the elongate body. An energy emitting device is coupled to a portion of the elongate body proximal the distal end of the elongate body to emit focused ultrasound.

Claims

1. An occlusion device, comprising:

an elongate body having a first lumen and a wall, the first lumen extending from a proximal end toward a distal end of the elongate body and the wall extending from the distal end towards the proximal end to a ledge that extends away from the wall, the wall including a wall opening such that a second lumen extends from the wall opening completely through the elongate body, where the second lumen is transverse to the first lumen;

an elongate structure having a lumen, the elongate structure extendably and rotatably positioned at least partially within the first lumen of the elongate body to pass through the first lumen to the second lumen;

a tissue apposition member that is extendably positioned within the lumen of the elongate structure; and

an energy emitting device extendably coupled to a portion of the elongate body proximal to the distal end of the elongate body.

2. The apparatus of claim 1, where the elongate body includes a surface defining a channel extending longitudinally between the first lumen and the second lumen.

3. The apparatus of claim 2, where the elongate structure includes a flexible portion along which the elongate structure bends under a compression force to push the elongate structure away from the channel of the elongate body.

4. The occlusion device of claim 2, where the elongate body includes a third lumen extending from the proximal end and toward the ledge of the elongate body.

5. The occlusion device of claim 4, including a suction arm that extends away from the ledge when extended from the third lumen.

6. The occlusion device of claim 1, where the elongate body includes an extendable portion proximal to the distal end of the elongate body.

7. The occlusion device of claim 1, where the tissue apposition member includes an elongate body having a lumen extending from a proximal end toward a distal end, the distal end including a piercing structure, and a pulling member extendably positioned within the lumen of the tissue apposition member.

8. A system for apposing tissues of a defective occlusion, comprising:

a catheter including;

a first elongate body having a catheter lumen; and

an occlusion device extendably positioned within the catheter lumen of first the elongate body, the occlusion device having a first lumen and a wall, the first lumen extending from a proximal end toward a distal end of the occlusion device and the wall extending from the distal end towards the proximal end to a ledge that extends away from the wall, the wall including a wall opening such that a second lumen extends from the wall opening completely through the occlusion device, where the second lumen is transverse to the first lumen;

a tissue apposition member extendably positioned within a lumen of a second elongate body;

a targeting device configured to locate and guide focused ultrasound to a target including apposed tissues; and

an energy emitting device configured to emit focused ultrasound at a high intensity to the target.

9. The system of claim 8, where the targeting device includes a magnetic resonance imaging device.

10. The system of claim 8, where the targeting device includes an imaging ultrasound device.

11. The system of claim 8, where the targeting device includes a monitoring functionality configured to monitor physical changes to the target induced by the focused ultrasound.

12. The system of claim 8, where the energy emitting device is configured to emit the focused ultrasound to the target from outside a human body.

13. The system of claim 8, where the energy emitting device is configured to emit the focused ultrasound to the target from within a human body.

14. The system of claim 8, where the energy emitting device configured to emit the focused ultrasound includes the targeting device.

15. The system of claim 8, where the tissue apposition member includes a pulling member extendably positioned within a lumen of the tissue apposition member.

16. The system of claim 15, where the pulling member includes a predefined shape configured to manipulate tissues of the defective occlusion.
