Claim 10:
11. The method of application according to claim 10, wherein
in a case where an implantation position of the plugging portion is close to the LAA opening, and the plugging portion basically seals the LAA opening without the residual cavity, the method of application comprises the following steps:
step 1: connecting the plugging portion to the pushing device through the first gathering member, stretching the covering portion to transform into a linear shape, and allowing the pushing device to push the LAA occluder to a human body through the delivery sheath;
step 2: gradually 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: operating the pushing device, such that the pushing device is separated from the plugging portion, and the plugging portion is used individually to seal the LAA opening.
