Abstract
Disclosed are methods and devices for endocardial left atrial appendage management (LAAM) by inversion and excision. The methods may comprise inserting an inverter apparatus into an interior cavity of the left atrial appendage (LAA) of a subject and inverting the LAA, closing the base portion of the inverted LAA with the one or more closure devices, separating the inverted LAA from the left atrium with a separation apparatus positioned at the base portion of the inverted LAA adjacent to the one or more closure devices, and removing the separated LAA from the subject.
Claims15
A method for left atrial appendage management comprising:
- inserting an inverter apparatus into an interior cavity of the left atrial appendage of a subject;
- engaging the inverter apparatus with an interior wall of the left atrial appendage;
- inverting the left atrial appendage by pulling the inverter apparatus into the left atrium until the left atrial appendage is substantially inverted;
- positioning one or more closure devices around a base portion of the inverted left atrial appendage;
- closing the base portion of the inverted left atrial appendage with the one or more closure devices;
- positioning a size reduction apparatus having an integrated cutting device around the inverted left atrial appendage in the left atrium;
- separating the inverted left atrial appendage from the left atrium at the base portion of the inverted left atrial appendage adjacent to the one or more closure devices with the integrated cutting device;
- and
- removing the separated left atrial appendage from the subject.
