ATRIAL APPENDAGE LIGATION

摘要

This disclosure relates to devices and methods for manipulating, such as with a suction based traction device, a target anatomic structure inside the body and delivering an ligation device around the anatomic structure. In particular examples, the target structure can be an atrial appendage, and the devices and methods are for atrial appendage ligation.

主权项

1. A device for ligating the left atrial appendage, comprising:
a delivery catheter configured to be directed into the pericardial space adjacent the left atrial appendage; a traction device extending through the delivery catheter that non-traumatically grasps an outer surface the left atrial appendage using suction and applies traction to the left atrial appendage, the traction device comprising two or more independent suckers that attach to surfaces of the left atrial appendage using suction; and a delivery device that delivers a ligation device to the left atrial appendage while the traction is applied by the traction device.
