Abstract
A device for occluding an atrial appendage includes a catheter-deliverable epicardial implant that is detachably secured to a delivery device. The implant includes an inflatable cuff that is positionable about the atrial appendage to an extent that, when adjustably inflated, the cuff physiologically occludes the atrial appendage. Such occlusion addresses health risks associated with atrial fibrillation and cardiac rhythm disorder.
Claims20
An epicardial implant, comprising:
- a positioning device defining an open interior, wherein the positioning device is configured to be detachably coupled with an implant delivery device such that the positioning device may be detached from the implant delivery device after the epicardial implant is in place about the atrial appendage;
- and
- at least one expandable cuff coupled with the positioning device;
- wherein the positioning device is configured to selectively move the expandable cuff toward and away from an atrial appendage to position the expandable cuff in a desired position relative to the atrial appendage;
- wherein the at least one expandable cuff is expandable into at least a portion of the open interior of the positioning device following placement of the expandable cuff into the desired position;
- and
- wherein the at least one expandable cuff is configured to physically occlude a base of the atrial appendage when expanded.

An epicardial implant, comprising:
- a positioning device defining an open interior between a first prong and a second prong, wherein the first prong and the second prong are movable between an open position and a closed position, wherein the positioning device is configured to be releasably coupled with an implant delivery device;
- at least one expandable cuff that is expandable into at least a portion of the open interior of the positioning device, wherein the at least one expandable cuff is configured to physically occlude a base of an atrial appendage when expanded;
- and
- a one-way valve that is configured to allow fluid to enter an interior of the at least one expandable cuff to expand the at least one expandable cuff.
1 more element
A method for treating an atrial appendage, the method comprising:
- providing an epicardial implant, the epicardial implant comprising:
- a positioning device defining an open interior;
- and
- at least one expandable cuff that is expandable into at least a portion of the open interior of the positioning device;
- positioning the epicardial implant around an external surface of the atrial appendage such that a base of the atrial appendage is disposed in the open interior of the positioning device;
- and
- expanding the at least one expandable cuff into the open interior of the positioning device to an extent sufficient to physically occlude the atrial appendage at the base.
