    摘要： The present invention relates to an occluder (100), comprising a meshed occlusion body (1) provided with a cavity (103), and a proximal hub (2), as well as a locking member (10) and a stopping member (13) both of which are located in the cavity (103). The distal end of the locking member (10) is connected to the distal end of the occlusion body (1). The stopping member (13) is disposed at the proximal end of the locking member (10). The proximal occluder head (2) is provided with a locking hole (15) in communication with the cavity (103). The radial size of the stopping member (13) is slightly larger than the diameter of the locking hole (15). The radial size of the locking member (10) is smaller than the diameter of the locking hole (15), and at least one of the proximal occluder head (2) and the stopping member (13) is an elastic member. An occlusion device comprises the occluder (100), a hollow delivery mechanism (200) and a traction member (4). The distal end of the traction member (4) is detachably connected to the proximal end of the locking member (10) of the occluder (100) after extending through the distal end of the delivery mechanism (200). The occlusion device has a simple locking structure, and simplifies the manufacturing process and the locking operation.

    摘要： Apparatus and methods for closing an access hole in a heart. The apparatus may include a heart plug that may include an absorbent mass that applies pressure to myocardial tissue in the access hole by absorption of fluid. The mass may have a length selected to match a length of the hole or to exceed the length of the hole by a predetermined amount. The mass may have an unexpanded state. The mass may have an expanded state. The expanded state may be a state in which the plug is partially saturated or saturated with a fluid. The mass may have an unexpanded state diameter that is selected for both rapid occlusion of the hole and sliding clearance within a delivery catheter having an outside diameter sized for traversal of the hole. The mass may include a matrix. The matrix may define interstitial space for absorption of the fluid.

    摘要： A left atrial appendage occluder (100) comprises an elastic closure disc (11) connected to a fixing structure (111) which is located on one side of the closure disc. The fixing structure (111) comprises a central end portion connecting with the closure disc and a plurality of interconnected and curved struts (121), wherein at least one anchoring tip (131) is provided near the end of at least one strut (121) with the anchoring tip (131) directed toward the closure disc (11). 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 deployment device. 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： The present invention provides a device for occluding an anatomical aperture, such as an atrial septal defect (ASD) or a patent foramen ovale (PFO). The occluder includes two sides connected by a central tube. In some embodiments, the occluder is formed from filaments that are joined together to define a substantially cylindrical form with openings defining struts. Upon the application of force, the struts deform into loops. The loops may be of various shapes, sizes, and configurations, and, in at least some embodiments, the loops have rounded peripheries. The occluder further includes a catch system that maintains its deployed state in vivo. When the occluder is deployed in vivo, the two sides are disposed on opposite sides of the septal tissue surrounding the aperture and the catch system in engaged so that the occluder closes the aperture.

    摘要： The present invention provides devices and methods for closing a physical anomaly comprising two overlapping layers of tissue, such as a patent foramen ovale ("PFO"). A PFO is comprised of two overlapping layers of malformed interatrial septa, the septum primum and the septum secundum, that form a tunnel between the right atrium and the left atrium. The closure device includes two wings connected to a central arm. The device is delivered through the PFO tunnel in a substantially linear configuration such that the central arm is seated within the PFO tunnel, the first wing extends into the right atrium, and the second wing extends into the left atrium. Once implanted, the closure device is reconfigured such that the arm is seated within the PFO tunnel, the first wing folds against the septum secundum, and the second wing folds against the septum primum, thereby sealing the defect.
