摘要： The present invention relates to a Left atrial appendage occluder comprising an elastic closure disc. The left atrial appendage occluder also comprises an elastic fixing frame connected with the closure disc and located on one side of the closure disc. The fixing frame comprises a central end connected with the closure disc and a plurality of interconnected and bent struts, wherein at least one anchor is set near the end of at least one strut with the anchor pointing toward the closure disc. The left atrial appendage occluder has a stable structure, a good positioning and sealing effect on the cavity wall in the left atrial appendage, and it is easy to position repeatedly; it can also be recycled before separating from a conveyor. When in surgical operation, the left atrial appendage occluder can select the position area based on the actual shape and size of the patient's left atrial appendage, so the surgical risk is lowered.

摘要： A medical device, including a fixing part, and having a compressed state and a deployed state after self-expansion, where the fixing part is provided with at least one anchoring member configured to be clamped in a gap on body tissue after the medical device is implanted into the body tissue, so as to anchor the medical device in the body. The medical device prevents damage to human tissue by providing anchoring members that are clamped in the gap in the human tissue rather than piercing through the human tissue after the medical device is implanted into the human body, thereby further preventing wound damage from enlarging due to movement of the human tissue. Normal operation of the medical device is achieved while ensuring good anchoring ability.

摘要： A left atrial appendage (LAA) occluder and an occluding system are provided. The LAA occluder includes a sealing portion and an ablation portion arranged in the sealing portion, as well as a hollow proximal connector at a proximal end of the sealing portion. The ablation portion is connected to the proximal connector. The ablation portion is used to freeze an LAA after being injected with cryogen so as to form an annular isolation band on an inner wall of the LAA for blocking the conduction of electrical signals between the LAA and a left atrium.

摘要： A left atrial appendage occluder (200) comprises a sealing part (220), a fixing part (210) disposed at one side of the sealing part (220), and a connection part (230) for connecting the sealing part (220) and the fixing part (210). The radial deformation capacity of the sealing part (220) is greater than the radial deformation capacity of the fixing part (210), and/or, the axial deformation capacity of the sealing part (220) is greater than the axial deformation capacity of the fixing part (210). In the left atrial appendage occluder (200), the radial or axial deformation capacity of the sealing part (220) is configured to be greater than the radial or axial deformation capacity of the fixing part (210), thereby avoiding the situation in which the sealing part (220) is not optimally fitted with the opening of the left atrial appendage (10) when the fixing part (210) is placed inside of the left atrial appendage (10), which in turn enhances the occlusion effect. Additionally, the sealing part (220) has great deformation capacity which reduces the risks of the sealing part (220) causing abrasion to the opening of the left atrial appendage, or even damaging the opening of the left atrial appendage. The fixing part (210) not only avoids the risks, but also fixes the occluder in the left atrial appendage (10) more effectively, and prevents the occluder (200) from being disengaged from the left atrial appendage.

摘要： A coated stent (100,200,300,400), comprises a coated unit (110,210,310,410), and an exposed unit (120,220,320,420) which is a ring-shaped structure and which is provided on the periphery (113,213,313) of an end portion (112,212,312) of the coated unit (110,210,310,410); the exposed unit (120,220,320,420) comprises an inward-tilting wave body (122,222,322,422), the inward-tilting wave body (122,222,322,422) comprising at least a first wave crest (122a,222a,322a) and a first wave rod (122c) connected to the first wave crest (122a,222a,322a); the position of the first wave crest (122a.222a,322a) is farther away from the coated unit (110,210,310,410) than other positions on the inward-tilting wave body (122,222,322,422); the first wave rod (122c) is planar, and from the first wave crest (122a,222a,322a) to an end of the exposed unit (120,220,320,420) near the coated unit (110,210,310,410), the radial distance from the inward-tilting wave body (122,222,322,422) to the central axis (102,202,302,402) of the coated unit (110,210,310,410) gradually increases. When the coated stent (100,200,300,400) is implanted into an arterial vessel (10), the inward-tilting wave body (122,222,322,422) forms a certain avoidance space due to the tilt to adapt to the curvature of a large curved side (11) of the arterial vessel (10), and prevents the inward-tilting wave body (122,222,322,422) from directly piercing a branch vessel (20).

摘要： A luminal stent (100) is provided, including a tubular main body (11) and a semi-releasing device (20) connected to the tubular main body (11). The tubular main body (11) includes a binding area (112) and a non-binding area (111) distributed in a circumferential direction. The semi-releasing device (20) includes a limiting rod (21) located outside the tubular main body (11), and binding lines (22) and limiting fasteners (23) arranged on the tubular main body (11). The binding lines (22) are arranged in the binding area (112). The binding lines (22) each include a fixed end (22a), a binding portion (22b) and a locking portion (22c) which are connected to one another. The fixed ends (22a) are fixedly connected to the tubular main body (11). Both the locking portions (22c) and the limiting fasteners (23) are detachably connected to the limiting rod (21). When both the locking portions (22c) and the limiting fasteners (23) are connected to the limiting rod (21), the binding lines (22) circumferentially constrain the binding area (112). By uniformly compressing a part of a circumferential area of the luminal stent (100), the luminal stent (100) can be in a semi-released state, thereby adjusting and positioning the luminal stent (100), and improving the accuracy of the axial and circumferential positioning of the luminal stent (100).
