摘要：
A left atrial appendage (LAA) occluder includes a sealing portion and a fixing portion connected to the sealing portion, and one or more sealed seed sources encapsulated with radioactive particles. The sealed seed sources are arranged on the sealing portion and/or the fixing portion (20) and configured for forming an annular isolation band on an inner wall of an LAA after the radioactive particles are released. The annular isolation band is configured for blocking the electrical signal conduction between the LAA and a left atrium. In the LAA occluder, the annular isolation band is formed on the inner wall of the LAA by the release of the radioactive particles in the sealed seed sources arranged on the sealing portion and/or the fixing portion.
