Abstract
Disclosed herein are embodiments of a method of treating a tissue of the heart, for example and without limitation, a tissue of the left atrial appendage, including twisting at least a portion of a tissue of the left atrial appendage to constrict an ostium of the left atrial appendage, and ablating at least a portion of the tissue of the heart, which can include a tissue of the left atrial appendage, the ostium of the left atrial appendage, and/or at least a portion of a tissue adjacent to the ostium of the left atrial appendage.
Claims32
A method of treating a tissue of the heart, comprising:
- twisting at least a portion of a tissue of a heart to constrict an ostium of the left atrial appendage;
- and
- ablating at least a portion of the left atrial appendage, at least a portion of the ostium of the left atrial appendage, and/or at least a portion of a tissue adjacent to the ostium of the left atrial appendage.
A method of treating a tissue of the heart, comprising:
- advancing an implant into the left atrial appendage and/or an ostium of the left atrial appendage;
- moving at least a portion of an outer surface of a first portion of the implant and/or one or more tissue anchors on or adjacent to the outer surface of the first portion of the implant against an inner wall surface of the left atrial appendage and/or against a surface of the ostium of the left atrial appendage;
- rotating the first portion of the implant from a first position to a second position to twist the left atrial appendage and cause an ostium of the left atrial appendage to constrict inwardly toward a portion of the implant;
- advancing a second treatment device toward the ostium of the left atrial appendage;
- and
- at least substantially electrically isolating a tissue of the left atrial appendage, a tissue of the ostium of the left atrial appendage, and/or a tissue adjacent to the ostium of the left atrial appendage.

A device for treating a tissue of the heart, comprising:
- an implant comprising a contact member configured to engage an inside tissue surface of the left atrial appendage and configured to rotate at least in a first direction from a first position to at least a second position to twist at least the left atrial appendage and constrict an ostium of the left atrial appendage;
- and
- a second treatment device configured to ablate a tissue that has been twisted by the implant.
