First Claim
Patent Images
1. A method of delivering a device to a left atrial appendage comprising:
- forming an opening in a chest of a patient suitable for surgical heart procedures;
advancing an implantable device through the opening and into a left atrium; and
passing the implantable device through the left atrium and positioning the implantable device at the left atrial appendage.

Abstract
A method of delivering and deploying the device for containing the emboli during a surgical procedure proximate to the heart. Access is gained to the heart and the left atrium such that a distal end of the delivery sheath can be located near the left atrial appendage. A distal end of a delivery catheter can be loaded with the device in a collapsed position and passed through the delivery sheath thereby delivering the device within the left atrial appendage. The device is expanded to contain emboli in the left atrium appendage.

10. A method of delivering a device to a left atrial appendage comprising:
-
forming an aperture in the outer wall of a left atrium of a heart;
advancing a delivery sheath through the aperture and into the left atrium;
positioning a distal end of the delivery sheath proximate to an orifice of the left atrial appendage while the delivery sheath extends through the left atrium and the aperture;
advancing a device through the delivery sheath and out of the distal end; and
implanting the device at the left atrial appendage. - View Dependent Claims (11, 12, 13)

14. A method of delivering a device to a left atrial appendage comprising:
-
providing a delivery sheath having a lumen and a distal end;
providing a transition catheter having a tip configured to reduce injury to a patient;
advancing the delivery sheath and transition catheter along the right atrium and through a transseptal hole and into the left atrium until a distal end of the delivery sheath is proximate to an orifice of a left atrial appendage;
removing the transition catheter from the delivery sheath;
distally advancing a device through the delivery sheath; and
implanting the device at the left atrial appendage while the distal end of the delivery sheath is disposed within the left atrial appendage. - View Dependent Claims (15, 16)

17. A method of delivering a device to a left atrial appendage comprising:
-
providing a left atrium access path through a pulmonary vein to a left atrial appendage;
advancing a delivery sheath along the left atrium access path until the delivery sheath is located proximate to the left atrial appendage;
advancing an implant through the delivery sheath until the implant passes out of a distal end of the delivery sheath; and
implanting the device at the left atrial appendage. - View Dependent Claims (18, 19)

20. A system for delivering a device to the left atrial appendage, the system comprising:
-
an implant sized and configured to prevent passage of embolic material from a left atrial appendage;
a delivery sheath defining a lumen and a distal end;
a transition catheter having an atraumatic tip and configured to slide through the lumen of the delivery sheath, the transition catheter being adapted to extend from the distal end of the delivery sheath when the distal end is proximate to the left atrial appendage; and
a delivery catheter removably coupled to the implant, the delivery catheter and implant being configured to pass through the lumen of the delivery sheath to the left atrial appendage. - View Dependent Claims (21, 22)
