Abstract

Disclosed is an adjustable occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device is removably carried by a deployment catheter. The device may be enlarged or reduced to facilitate optimal placement or removal. Methods are also disclosed.

Claims

1. A method for implanting a device in the left atrial appendage, comprising:

providing an implantable device having a proximal end and a distal end, a threaded core, and a threaded aperture at the proximal end, the implantable device having a collapsed configuration and an expanded configuration;

expanding the implantable device in the left atrial appendage to a first position; and

repositioning the implantable device in the left atrial appendage by at least partially collapsing the implantable device by rotating said threaded core in a first direction in said threaded aperture to cause the threaded core to advance distally relative to the threaded aperture; and

re-expanding the implantable device to a second position within the left atrial appendage by rotation of said threaded core in a second direction opposite the first direction.

2. The method of claim 1, wherein the implantable device is delivered to the left atrial appendage using a deployment catheter.

3. The method of claim 1, wherein the implantable device is moveable between its collapsed configuration and its expanded configuration by causing relative movement between proximal and distal ends of the device.

4. A method for implanting a device in an opening of a patient, the device having a proximal end, a distal end, and a threaded aperture at the proximal end for use with a threaded core, the method comprising:

delivering a sheath having a proximal end and a distal end to a location near the opening;

advancing an implantable device through the sheath to the location, the device being outwardly biased to an expanded configuration and being held in a collapsed configuration by the threaded core while being advanced through the sheath;

moving the implantable device out of the distal end of the sheath and into the opening, the implantable device remaining held in the collapsed configuration while positioned in the opening; and

expanding the implantable device at least partially in the opening by rotation of said threaded core such that the threaded core moves proximally.

5. The method of claim 4, wherein the opening is an opening in the heart.

6. The method of claim 4, wherein the opening is a left atrial appendage.

7. The method of claim 4, wherein the device is collapsed by increasing the distance between the proximal and distal ends of the device.

8. The method of claim 4, wherein the device is collapsed by engaging the threaded core against a distal surface of the device while rotating said threaded core connected to a proximal end of the device.

9. The method of claim 4, wherein during the step of expanding the implantable device, the rotation of the threaded core expands the device by relieving stress on the device.

10. The method of claim 4, further comprising re-collapsing the device while the device is in the opening.

11. The method of claim 10, further comprising repositioning the device within the opening and re-expanding the device.

12. The method of claim 10, further comprising proximally retracting the re-collapsed device within the sheath.
