Claim 9:
10. A method of application for a left atrial appendage (LAA) occluder, applied to the LAA occluder according to claim 1, and comprising:
detecting an LAA anatomy of a patient, wherein
in a case where an implantation position of the plugging portion is apart from an LAA opening, and an obvious residual cavity near the LAA opening is not sealed, the method of application comprises the following steps:
step 1: sequentially connecting the plugging portion, the connecting portion and the covering portion, providing an end of the covering portion away from the connecting portion on a tip of the pushing device, stretching the covering portion and the plugging portion to transform into a linear shape, and allowing the pushing device to push the LAA occluder to a human body through a delivery sheath;
step 2: pushing, at the implantation position, the plugging portion out of the delivery sheath, wherein the first support mesh of the plugging portion away from the connecting portion expands gradually to form a small plane for pre-targeting; a remaining part of the first support mesh expands sequentially, such that the plugging portion gradually attaches to LAA tissues; and the anchoring members expand at the same time to grasp the LAA tissues; and
step 3: sequentially pushing the connecting portion and the covering portion out of the delivery sheath, wherein the covering portion expands to cover the LAA opening.
