Abstract
A left atrial appendage (LAA) occluder and an LAA occlusion system are disclosed. The LAA occluder enables an increased surgical success rate by allowing repeated good positioning, retrieval and release of the occluder and avoiding the problem of entanglement of the occluding stent during surgery. The LAA occluder includes an occluding stent, a proximal securing member a distal securing member. The occluding stent includes an occlusion structure and a traction structure. The delivery device includes a hollow push tube and a control shaft. The distal securing member can be driven by the control shaft to move toward the proximal securing member until a first distal end of the occlusion structure is in a collapsed configuration, where the distal securing member is blocked from further movement, avoiding the problem of entanglement arising from inward rolling of the occluding stent in the vent of human error.
